Im getting my enigine rebuilt for graduation.
My question is:
1. How much for a rebuilt for NOS
2. Price to install Cam and 1.6RR
3. Heads Port & Poilish W/ Valve Job
4. Engine Bored
5. And intake ported and gasket matched
6. Possibly some throttle body work
Im just getting some info from you guys then decided on what to do first. I think i should do the cam, RR, Bore first. Then later on this summer get the heads done with intake. I want to do this because i rather have a V6 because its different.

Why not try the easy way.
Ask for a 3.4 long block outta the yard.
I paid $800 for a40K motor.
Your neck of the woods, it'll be better prices!

Karl,
if the boy wants to rebuild his 3.1, let him rebuild his 3.1! anywhoot. I'm not sure on prices for a rebuild, i had a new 2.8L/3.0L after the bore over dropped into my 85 bird, it's a pretty decent ride. Most times i do believe that boring the motor over will be included in the rebuild, just so everything is matched properly, as far instilation of the performance parts it shouldn't cost that much, being that the motor will be disassembled anyway, most likely they won't charge much for labor. When i had my tranny rebuilt about a month ago, the guy through in a Vette servo, and shift kit with no extra charge for labor because he was going to have to do it anyway. So, my advice, is just buy the parts, and ask the guy to install them.


p.s.
are u graduating from high school are college, i just graduated from high school yesterday, now on to the fascinating world of college

Most machine shops will charge anywhere from 8 to 10 for each hole.The piston size shouldn't affect the price of a rebuild kit.Well...in most places anyway.
As for the cam install and rockers...that would be mostly up to you.If you have someone rebuild the engine for you it would be included in the cost.
Just to give ya an idea....when I/we rebuilt my engine,here is what it cost me...

• clean engine block---$30
• install cam bearings-$15
• press rods on .030 pistons--$20
• bore block---$60
• clean/install valve seals on heads--$20/
  $25
• rebuild kit---$380.The actual cost was like $650 but fortunatly for me a friend worked there at the time.I got it at his cost.
• $300 to have someone pull the engine,disassemble,rebuild and install engine.
• coolent,oil,plugs,cap/rotor,upper and lower radiator hoses,trans cooler,shift kit and roller tip rockers---$259

Total of $1089.After everytnig was done it was clost to $1200.

I didn't include things like new hose clamps,paint for the engine,the $40 I wasted on that ****ty stainless steel hose dress up crap,heater control valve,coolent sensor(on head),coolent sensor(on intake)and degreaser for the engine bay and frame.


You should do the porting and polishing yourself or have a friend do it for ya.I don't know of any machine shops who would do that.Besides a speed shop.Then your gona pay big bucks.

Kevin, thanks for the prices!! On that $30 block cleaning price, was that a hot tank job, or did they also magnaflux the block?

What was in that rebuild kit if the actual cost was $650?? Was it the normal rod & main bearings, pistons, rings, timing chain, & freeze plug kit? I was told to buy my rebuild kit from the place that does the machine work, because they'd "care more" about their machine work... but I'm not spending $650. (I have no machine shop friends, hehe)

Naw,that was just a hot tank cleaning.Atleast I don't think they did a magnaflux on the block
The kit was complete save for the rods and crank.

• all gaskets
• all bearings-.010 over except cam bearings
• pistons/rings-.030 over
• oil pump assembly
• cam/lifters
• freeze plugs
• timing set

I feel like I'm forgetting something.

I still can't figure out why it would cost so much.You'd think since it has smaller and less parts then a v8 it would be somewhat cheaper Maybe it's a NAPA thing?

I found at http://www.Northernautoparts.com have the kits for far less then $650.$314 Is what they have listed now.That's where I got the Accel ignition module,roller tip rockers,shift kit and the trany cooler.They have some really good prices.And decent delivery.

BTW,I forgot to mention it cost me $75 to have the crank turned .010

I AGREE if ya really wanna spend it on machining & parts and and and
BUT.......
IF ya put out that much effort for prices,

Phoning around, or asking others for locations of a running 3.4 long block, that I've heard others getting for as low as under $500 (and I paid $800) and the results are just as positive, if not better. I sold the left over parts for a bit over $100. That helped cover the cost of the gasket set and the few odds and ends.

I'm saying, do the math.
Simple economics.

So far, seeing the above costs, rebuilding that smaller engine costs twice as much as what I paid for a larger, seasoned engine, that worked, as soon as I turned the key.

I'm trying to bring back to life my 2.8 in my S-10 Blazer. I'm using left over parts from the ruined 2.8 MPFI from the Firebird. I also need a trans. I'd rather spend the money on a trans, instead of the Cam ($50), lifters ($35), and timing chain ($35), that I heard I could get for less. For those prices, I get a trans rebuild kit (or towards a rebuild kit) or a working 700R4 tranny. That's my simple math.
When I do rebuild this engine, I'm getting a running 3.4 block, for about $800 or the more milage, lower priced ones.

I'll bet you could get a good running 3.1 for about $300 and slip that in, just to keep going.

A wrecking yard engine is a dime a dozen, compared to the machining costs of these V-6 engines.

What we are having fun with (a little V-6), working on, IS NOT a Corvette L-88, nor a Chevelle LS-6, or a Cuda HEMI, or even a Supercharged Studebaker Avanti R-3 (289 with a Paxton Supercharger, fastest production car, 1963-Bonneville Salt Flats)! Those engines are worth the machining costs and associated effort.

Ask anyone else, having done the 2.8 - 3.4 swap, if it was worth the effort compared to rebuilding the original block.

NEW 3.4 engines from GM parts counter go for about $1400-$1600 w/a 12,000 mile warranty.
I seem to recall some one, here, whose Dad works at a Chevy Dealership, happens to live in Maryland, that may BE ABLE toget you a deal.

zerogauge

hmmm. i sure hope you arent doing any of the work. you just might learn something.

the main size isnt an option...its a measurement that needs specified.
say your crank is 10 under then you need 10 over bearings.
if the mains are 30 under you get 30 over mains.

like your pistons...
you bore a cylinder over 30 you(which removes .030 from the cylinder wall)you need to get larger pistons. .030 over to make up for the removed area.

or thats how i understand it. feel free to correct me.

FAST RS

My mechaninc said he would reuild mine When it Went for 1600 with up to a 100,000 mile warreny for around 1600. It look slike i might be there soon too. I want to kep he origional block so later inlife if i still have my car an they are colectors items it will have matching numbrs.

TomP

I guess it is a NAPA thing... I saw rebuild kits in the PAW catalog for that kind of price. I'd actually buy two different kits, a piston kit and a bearing kit. I'd put in a Crane Compucam; so I wouldn't need the stock cam that comes in the "master" rebuild kit.

GM also makes that high-pressure spring to go into the 2.8 oil pump... altho I think I'd just get a high-pressure (or high-flow? Maybe a high flow'd be better..) pump as part of the kit instead of play with springs & shims & etc.

$75 to turn the crank.. ouch. I think Northern Auto sells a "rebuilt" 2.8 crank for only $50... of course that thing could be turned 0.30 under, who knows!

I think the absolute "least" I'd buy from the machine shop would be pistons & rings... they could fit the pistons/rings to the cylinders & press them on the rods. Then I could just do the rod & main bearings myself. I still need to buy a telescoping gauge & micrometer gauge to do that, though. Of course if it comes down to it, I'll just use Plastigage.

If you are PLANNING on running NOS - TELL EVERYONE, so your parts are specific to that NOS usage.
That detail makes a difference.
The best oil pumps are used in the S-10 2.8 blocks. Mine, after 211,500 miles, still puts out 40-80 PSI.

Well, a couple guys have told me to buy the kit from the machine shop. Reason is, the machine shop will care more about the engine work since they know they're making extra money off of me. Makes sense...

Lemme just ask a question since we're talkin about boreing.... If you bore the 2.8 over .030 then it becomes a 3.1 right? So, does that mean u cant bore a 3.1 block anymore?

Kevin S

When you bore a 2.8 .030 over you only gain about 3 cubic inches.That roughly makes it a 2.9

173 to a 176ci after a .030 bore.

It's not even worth the overbore if you don't need to, right? Say the cylinders will clean up with a 0.10 overbore... is the extra 0.20 worth it?

Red91Bird

When i did my 3.1L hp and ft/tq was the goal...

Nos is a trick monster how mush do you wanna run? i will assume under 90hp levels.

Cam install depends on the shop, most charge 50/hour. To do the cam your looking at about 5 to 7 hours work they will charge.

Cam prices are 59 to 159 depending on what ya wanna get.

Rockers run 200 to 359 depending on what you wanna get - NON roller rockes are alot cheaper.

Heads - generally you can get em done for about 300 to 450.00 Personally i would buy race preped heads form GM. They are ready to rock and about 350 a pop i think....

Engine boring runs about 15 to 20 per hole. DO NOT forget to get the block hot tanked, sonic checked, new freezeplugs and honed!!!!
Also get the oil valley painted - it aids if the oil return process.

Not sure on this one - i did it myself - very easy and fun. BE SURE to read up in it or you WILL destroy yer intake - or atleast the bottom piece.

TB - most fiero shops will rework you TB for 200 to 300 bucks. GREAT investment!!!


What i suggest is collecting the stuff FIRST... get it all lined up and then do it... infact get a old block and have it preped the week before you pull the old block. DO NOT piecemeal a engine together that you have to openup and close, open up and close... it will develope leaks - will never tune right and is a major PITA

Just my 2 cents

sorry for keep asking stupid questions. But are these it i found Pro Magnum 1.6RR 3/8 stud? I want the best to but in. I want it to be a sleeper. And I still have to find a 3.73 Posi rear. It will so much cheaper to find one then to make my posi but buying parts. And im looking into getting a full 3in exhaust also.

I plan to rebuild my 2.8... Iwould make sure you do the 30 over bore, my father says go 40 over, but it is up to you...

TomP

PimpRide92, it might not be cheaper to find the 3.73/posi axle.

I swapped a 3.73/posi/disc axle into my car last September (2000). The axle cost me $150 from the junkyard.

Then, I rebuilt the axle with: new axleshaft bearings (commonly mis-named "rear wheel bearings), axleshaft seals, painted with POR-15, diff fluid, posi additive, rear cover gasket. I rebuilt the axle's brakes (I rebuilt one caliper, the other was toast so I had to buy a pre-rebuilt one, had to make a steel brake line, new caliper mounting bolts & slides). Then, I installed the axle (free) and hooked up the brakes (J65 master cyl, J65 prop valve, new rear brake hoses, tons of brake fluid).

Final cost, with axle price & rebuild price: $600. For $600, I could've bought a 3.73 gearset for $200, a used posi for $75, and had someone install the two for $200. Of course, I got to brag about doing it myself, and got rear disc brakes out of the deal, but it's something to think about.

Oh, and that's a "close" part #, it'll probaby work, but our heads need rocker arms that use a 10mm stud. As you know, 3/8" is pretty damn close to 10mm.

But im also think of getting an older IROC also. Depends if i can find one for a good price. How long do you think they would take to rebuild it? With all the above engine mods?

It took me and my friend a weekend to pull a broken 2.8 and install a "good for a while" 2.8.

But for the rebuild, I'd say 1-2 weeks of working "after work/school". The machine shop takes up a lot of time, too.. don't forget to account for that. Plus you want to be careful... unless someone's an absolute pro, there's no way they could do an engine rebuild "the right way" (note: not just doing a re-ring or changing a bearing) in a weekend.
