The part numbers are 65171 for the 1 7/8s or 65172 for the 2" long tubes anyone have them or have installed them.

2" primaries? You sure thats not for a big block? Thats too big to fit onto a small block head.

JERRYWHO

The Headers are for a small block. I have ran 2 to 2 1/8 step headers with 4 inch collectors on small blocks before. Stahl makes 2" headers for our cars but I don't like how one pipe on each side runs out the fender and around the frame to the collector.

uhhh, thats a mini motor for RC car. LMAO

Craig Moates

Those are valid numbers. I had the same question, seems like it'd be tough to fit in there. But that's what is called out. They're like $500+, but for 2" primaries, that's sick and cool.

I talked to the Hedman guys, they weren't that friendly or helpful. They just said "Nah, won't work". Didn't really jive with their offerings and listings, but I just got tired of fighting to get some info from them, figured I could get some better info here.

i am not sure those tight 2inchers shorties would be any better than a good set of 1 3/4 long tubes like hookers

unless your making like over 500hp or so, you can benefit from bigger tubes but how many do that?

Craig Moates

Well I'm looking to make 600+ on the motor. 441ci 12.5:1

Hedman makes "Hustler" 1 3/4, 1 7/8 and 2" primary long tubes for our chassis, but they require a mini starter and a remote oil filter. Living in CA, I would also have to install AIR fittings and get them referee'd for smog. I'm considering it, but it seems like a lot of hassle and expense, and for the planned hot street engine, I don't think it will make that much difference. Just thought I'd throw it out there.

Me too ;^).

Like these...Heddman Hustlers with 1 7/8" primaries 3.5" collectors. Mini starter for sure but you can get by without a oil filter reloctor kit. Just have to use the short filter.

Edit:
For what it's worth the adapter you have to run to fit big tube to the sbc needs to be completely ground out by the installer. The adapter comes with little 3/4" or so hole in the location needed, but you must manually grind them to fit the gasket.

double post im stupid

Boomin Boy

i dont think you'll need 2 inch primaries until you're around 1000 HP IMO

paul_huryk

If you look at those headers posted, the bolt holes are not in the proper SBC places - you will need adapters (or heads with the correct bolt pattern).

phoenix305

hey paul_huryk how is your 350 a LG4? just curious.

paul_huryk

Very easily - I swapped the 305 out for a 350 while still using the factory LG4 carb, distributor, and computer.

phoenix305

nice just curious, and its that fast with all those stock engine components?

I believe pauls pass in the sig was made with the use of nitrous.

Stahl headers? Besides relocating the brake lines, steering shaft, AC removal, etc etc. - Do you realize how much you have to chop up the front end of the car to get those on right? Not your simple slide in place and bolt up...

I've seen them on a blown SBC IROC some time ago. I commented on his home built headers. After telling me about what he had to go through to get them to fit the car, he stated he would NOT do it again.

paul_huryk

Its a stock bottom end out of a 1990 L98 Vette with ported heads, 219/219 Accel cam, Performer RPM intake, and a 3-1/2" exhaust system. The pass in my sig was on nitrous about 5 years ago - its a lot faster now. I ran 12.5 at 113mph on the motor in 2003. The car will get booted from Englishtown with the nitrous now - need a rollcage.

Marc 85Z28

iTrader: (3)

LG4 carb + distributor + computer+ completely different engine = LG4?

I have a Corvette 350 block, with Corvette wheels and brakes. Does that make my car a Vette?

Rabbitt

dude.. must we all find everything to pick at each other for? jesus

He was using the stock LG4 intake and firing components.. Not an LG4, but its saying that the LG4 intake and firing components are just fine to go that fast, thats all

Its about displacement and rpm more than just horsepower. Look at big block headers.

Boomin Boy

its still a small block so im assuming its under 454 cubes and spinning at less than 8000 rpm..still too big IMO

Craig Moates

Ah well, I talked with everyone and their brother. Aything over 1-3/4" is out for the Firebird. Apparently for the 82-92 Camaro, there's a little more clearance along the body rails than the Firebird. Who would have thought?

So, I guess it's Hooker 2210's for me and my SBC 441...

unknown_host

iTrader: (1)

I would agree with you if it was a n/a motor, but i am assuming from his sig he is going to still be running a 200 shot on this motor.

Its not going to make or break his motor, I Just know people who have seen gains making less than 1000 horsepower by going to a larger header.

There is a general consensus on this forum that no motor should EVER need more than 1 3/4" headers and single 3" exhaust. I have been trying to break that for a while now.

Sounds like you have some badass cars, what does the malibu run out of curiosity?

441...big cube small blocks are awesome...4" stroke and 4.185" bore? Sounds killer, anywhere we can see progress pics?

Craig Moates

4.125" stroke, 4.125" bore, 6.125" rods. Yes, I'll be taking some pics soon as it goes together...

Here's a picture of the 2" Heddman Hustlers that I have. Sorry as I have yet to install them yet though "still gathering cash & parts"

The folks from Heddman say that you will have fitament problems with stock pieces. I have a tubular K Member & will be using a mini starter. They have a steep price tag as well, a dab over $750.



Hope this helps, Bruce

Interesting collectors on those...

70GTO

IHI is correct ("as normal") as the supplied steel adapter plates leave a lot to be desired & will need a lot of grinding to match the exhaust port pattern of your heads. I tossed them and made a set of them from 3/8" flat aluminun "lighter & easier to work.

Oh yea, the $750 price included the Jet hot coating.

Bruce

IHI

iTrader: (1)

LMAO, whats that supposed to mean?? Spend enough money and screw enough stuff up eventually you learn things

70GTO

I purchased the headers thru Jet Hot & I ordered them with the collectors since i'm gonna be running the car quite a bit on the street.

70GTO

Definantly a complement , As you have answered a many of my questions in my never ending quest to finish my money pit of a project :hail: :hail:

Sell it, best advise ever!!

70GTO

unknown_host, I agreewith ya.

When I built the engine in my signature I refered to a recipe from The Best of Hot Rod magazine "How to build Big Inch Chevy Small Blocks". They had dyno results & to make a long story short, the large cube small blocks made more HP & torque with the larger 2" tube headers. Also the enging they were testing was N/A


IHI, "Sell it, best advise ever!!",

Great advice, but I'm hooked & it's a lot of fun " I Think"!!!

I was getting some powder coating done, and was looking through the sample book the powder coater has. It listed a "super high temprature" powder coating, that is either satin black, or a finish that looks a lot like the ceramic coating. Anybody ever used high-temp powder coating on their headers before?

IHI

iTrader: (1)

I have'nt seen any high temp powder coated headers, but I can attest the the fact Jet-Hot is simply amazing to say the least. We race with a couple from MN that had the headers for their 66 stang done by Jet-Hot, literally 2-3minutes after they're back in the pits you can grab the headers.

I was going to send mine out before installing the motor, but figured with all the headaches these 3rd gens throw at us, I better run them first and let the dents, dings from fitting take place before I spend $277 (quoated from J/H) to have then coated. Glad I did, Hooker Super comps + wheelies = A-arms slamming into the headers and denting the pipes badly.

But with our extreme under hood temps as they are even stock, coupled with the fact of poor air circulation by factory design, the thermal coatings is a great investment.

70GTO, sell it!! Take up yard work or something, these cars are like drugs as they consume you and take over your life!! Least with yard work you can get your money back outta the place when you sell....try saying that about a project car LOL!!

Trevor86TA

I had high temp (1600*) powder put on my Hooker 2210s and I don't think it was worth it. The paint got somewhat scratched on install and burned off on a few hot spots in the 4-5 hours it ran this year. It didn't turn out as well as I thought it would. I should have just ceramic coated them. I'll try and post pics if I can borrow a camera.

Just bought a set. I think I am going to run Flowmaster Topten 3.5" mufflers off the headers and just turn them down. I don't know how gret my ground clearance is going to be...
Anybody have toptens?

wow im dumb

Those will never work with your car!!!

I'll help bail you out. Tell you what, I'll cover the cost of what you had to pay just cause I'm a nice guy...

Those do look sweet...

Its JUNK.. I do ceramic,thermal and powder coating. The Hi temp powder is JUNK.

Craig Moates

Digging up this thread...

I went ahead with some 2210's on that 441. With some dyno-shop 1-7/8", the motor made 680 at the crank. With the 2210's and a dual 3"->3-1/2" in the car, it made 440 at the wheels. Getting rid of the Y-pipe and running open headers on the 2210's, it got up to 530hp at the wheels. That's too much loss, and I'm looking now to step up the header sizing.

Anyone have some insight into fitment issues? I've got an 87 T/A, tubular K-member, mini-starter, remote-mounted oil filter, Dart Iron Eagle spread-rail block, T-56.

I'm really leaning toward some 1-7/8"->2" stepped Hedman Husler headers, part # 65172. Any thoughts are certainly welcomed.

And, of course, if anyone has something along those lines, I'd love to hear about it.

And, if anyone needs some coated 2210's with Y-pipe, bullet, and Borla system out back, you know where to find me. What's restrictive for me could be wide-open for another ;^).

Rabbitt

yah, you are losing a good 30-50hp at the rear wheels (not sure on the loss of power with the T-56).. Have you thought of having custom headers made? i mean, with how much you put into the motor, it would be worth it and you could have whatever O.D. size you want.

CaptPicardsZ28

How much for those headers without the y-pipe?

TRAXION

Wow. Simply wow. 90 WHEEL horsepower loss due to the full exhaust.

Heck, it doesn't look like even a 4" Mufflex system is big enough for your motor. However it would be a step in the right direction. Two 3" pipes in and a 4" out at the wye.

By the way Jerrywho who started this post wound up making his own 1 7/8" headers. The man has a lot of skills and never ceases to amaze me. Allen
