Shifty... and others, tell me what you think
I am considering buying the whole setup... all I will need is a fuel pump and 350 injectors to complete the swap...
$2900 shipped including bored manifold, 50mm TB with Ultimate TBI mods, chip, injector spacer, etc.
I wouldn't mind a new motor & doubling my HP for less than $3k... it's a direct swap too

Shipping: When using the ebay shipping calculator, please be sure to enter business/commercial if picking up at a truck terminal - your quote will be high if going to a residence.
Drop in replacement 350/5.7L motor for your 1987-95 TBI Truck, Suburban, Tahoe, TPI/TBI Camaro, Firebird, Caprice, Hot Rod & more. This motor will give you more pulling power, more horsepower, and get better gas mileage than your stock TBI motor – all while running on low octane pump gas.
Best of all – We can include a high flow TBI intake kit + ECM PROM consisting of bored throttle body, adjustable fuel pressure regulator, performance intake manifold, gaskets, and custom programmed PROM setup for this motor – so you can get the full 313hp/387ft/lb. Don't be fooled by other "computer compatible" TBI 300hp motors being sold on ebay - you will need a custom PROM and high flow intake kit to get that HP and to my knowledge, no other seller offers this.
12 month, 12000 mile written warranty is available – email for details.
We use only premium USA made components and over 99% new parts to get you this “better and stronger than factory” motor. If you are looking for a cheap replacement TBI motor – this engine is not for you. We equip these with the lastest GM 880 4-bolt main roller blocks, GM 450hp powder metal rods (same type used in the LS1/LT4), roller cam setup, new valve train including new GM valves, performance springs and retainers, performance balancer and more. We have dynoed a copy of this motor at 313hp/387ftlbs on pump gas (same heads, cam, porting, intake kit, PROM, etc). However, the motor being sold here has never been run since remanufacture
Comes complete as shown in the first photo – this photo is the actual motor you will receive
Have Questions: Email Horsepowerguy@sbcglobal.net, or 512-791-5725
Motor will be completely sealed up with valve covers, oil pan, and all openings taped over.
Details are:
Late model ported TBI Heads – performance built NEW valves, springs, retainers + more
GM castings – thermally cleaned, maniflux checked for cracks & flatness & painted w/ high temp engine paint
New .500” lift GM springs, hardened keepers, & new GM light weight retainers
New GM heavy duty1-piece valves 1.94/1.50 – these are the valves GM switched to in the early 90’s in the LT1 & Vortec motors
New positive valve stem seals – these won’t leak at startup like your stock units and most other rebuilds
Intake and exhaust ports are cut and reworked to increase flow (no other TBI motor will this kind of power without this)
performance valve job, bowl blended, Intake ports cut to remove major restrictions
4-bolt main performance Short Block 355cu-in – (good to 450hp):
GM 880 roller casting 4-bolt block w/ 1-piece rear seal, roller cam setup – thermailly cleaned, deck & mains checked, painted

Car: currently thirdgenless!!!
I read through it and didn't see it but find out what the casting numbers on the heads are and get some specs on the cam.
If it's the swirl port heads and the peanut cam, they gotta go!

The engine mentioned above has ported swirl ports on it and a cam to this spec.
Roller Cam setup : Performace ground roller cam: 209/210 in/ex duration at .050”, .459/.459” lift in/ex, 115LSA
Seems to back up my claim on the swirl ports. Engine dyno says about 315 FWHP and just short of 390 ft/lbs. With good prom tuning, adequate injectors, and the intake kit they give you, I could EASILY see that coming out of this engine. That is very similar to what I obtained with a LT1 cam, 1.6:1 rockers, and ported 193s on a 9.5:1 355 based off RWHP#s.
They claim according to the dyno chart 350 ft/lbs from 2,000-4,500 which was verified IMO, by my own 355.
The LT1 roller cam is slightly smaller(more lift that this one w/ 1.6:1s) and my heads surely had a little more time into them and probably flowed a little better.

Well it said they they use ported TBI heads. . . . . . not too bad of a deal for a bolt in deal. I think for the price if you willing to put together your own motor and do your own tuning you could come out better, alot better. Lets set a core price for a 350 or even a just a short block at $100 for some thing than can be rebuilt or mostly any way. Heads will go in to the trash or be resold, rod trash or resold, pistons and rings trash, and the oil pump and rod trash. Keep the oil pan and bolts the timing chain cover and bolts, valve covers and bolts, the crank and block. I was bord so I took a look at what summit offered any other mail order place will give the like results.
ARP head bolts Arp-134-3601 49.88
World S/R torquer heads 374.88 each
Oil pump kit Summit SES-3-60-08-022
Speed-Pro Hypernutectic pistons 17.99 each
Gasket set FEL-KS2600 39.95
Summit Rods 4030 SME-3-48-05-100 263.95
Clevite H-series Rods bearings 55.60
Clevite H-series Mains 51.95
Clevite Cam bearins 19.95
180 for what ever cam and lifter kit you want
Comp Cams Magnum pushrods 7372-1689.88
Comp Cams magnum Steel roller tip rockers 145.88
Cloyes Heavy duty Timing chain 15.88
thats 1738.71 leaving you 1161.29 for shipping, things I missed the prep work on the block and crank. Might be able to cram in some bigger injectors and a ELB and a 12 pack.
umm but that might be alittle over kill for just a 300 hp motor. . . .

The only problem I see is those S/R torquers are about the junkiest head you can buy for a small block. Spend another $100.00 a head and get a proven Dart Iron Eagle head. 180 CC works great for a street 350 with a mild cam.

Considering the price, is it worth it to buy the motor and drop it right in?
I really dont have time to build a motor, when I saw this it put a smile on my face!

i would say so, machine shop time and your time are worth money imo......
Then again i'm the same guy who does and will always build my own engine though because, i'm just cheap but, all in all it sounds like a good deal to me.
Though if i built it i'd use a different cam and heads....

Dart Iron Eagle
The New Vortec Bowtie head.
Typical Bathtube shape SBC head (unshrouds the valves but hurts quench and compression).
I think this guy has the tuning pretty much down, just noticed he is the same place that I bought my AFPR with Vacuum compensation from a while back.
Properly tuned with a full exhaust, a dual snorkel with a Truck lid and filter, and traction, I have a feeling this would be in the mid-low 13s.

Regardless of the heads, I would still be getting a drop-in replacement motor for my car that is doubling my stock HP, for $3000 shipped, you can't complain, right? Even down the line I could still swap heads if I wanted more power. I don't have time to build a motor because of my work schedule, I was looking into a crate motor, but if I was to buy one, my car would end up being carburated; I don't want that.
Performance wise, I am looking to do this motor swap, full exhaust, rebuild the transmission, get an aluminum driveshaft, and a 3.23 posi rear, all of this by the time the snow melts for good up here. Most of my time will be in the body shop because I have to get the car repainted by spring as well.

Hey Jim, do me a favor and edit your original post with pictures/little more descriptive and no eBay link? This thread will make no sense to anyone in about a week...

Jim: That seems like a nice street motor. Swirl port heads or not, 313 HP is 313 HP. I'm not a fan of swirl ports, but if those numbers are as advertised that will be a substantial improvement over stock! And at a later date, you can swap the heads when you're no longer happy with the outout. Man, the horse power bug never goes away!

I don't know if I would buy that motor. For $1500 you can get a new LO5 longblock. You could then port the heads yourself and run a carb intake with an adapter plate. Adding a roller cam of your choice will add another $300 or so (or less with used LT1 cam). You could then spend that extra cash on injectors, 350 ESC module, 350 knock sensor, and tuning equiptment that will be required to run that motor. I would follow Fast355's advice and model a motor after his. That combo should give you the results you desire for less money without leaving anything out (tuning, fuel, KS, and ESC, tuning, and more tuning) and be a lot of fun to drive.

I think he was just looking for something to drop in and go, even if it does cost a few extra bucks.
