None of the above. The forged pistons are good for your build, but if I were going for 500 hp I'd go with a quality forged crank, rods and pistons. They may not make a kit that has everything you want, so don't be afraid to order separate parts.

Stay away from Eagle brand parts.

I'm doing a mild build on my 95. Maybe 330 flywheel hp, but I'm using a Callies dragon slayer forged crank, scat forged rods, and forged pistons.

^^^^^^^^EXACTLY^^^^^^^^ my thoughts!

Definately the Callies Dragonslayer crank.....but I'd also go with a Callies Rotating Assembly since you have an unlimited budget.....CALL THEM.....I'm pretty sure they'll ship to your location:

Rotating Assemblies - Callies Performance Products

Then......for heads cam (since your budget is "unlimited") I'd recommend:

An Advanced Induction 190cc Head/cam set (call them, too!

Advanced Induction - LSX Heads & Cam Kits

Make sure that you have your engine spec's and the spec's from your rotating assembly when you call Advanced Induction. They will spec your heads/cam to your set-up for max performance.

Information they will need......

Block deck height;
Piston Specs....flat-top or dished....cc reliefs;
Rod length (I recommend 6" rods)
Desired static compresion ratio.


Good Luck :LS1LT1flag: !!!!

Also, the trickflow 430 kit will only yield 430 CRANK horsepower. For the same cost, actually less, you can have 430 WHEEL horsepower from advanced induction or Lloyd Elliot porting your stock heads and grinding you a custom cam. You should put the brakes on this project and do some homework, reading ALOT more about the LT platform.

Eagle cast cranks break with as little as 400hp, and the Scats are not much better. If you are goign to replace the factory crank, you MUST go forged. The stock cast crank can survive over 700 horsepower.

 

My budget is unlimited I want about 500HP crank, so if somebody can write detail specification of parts I need to buy, that will be great

My idea was that with Trick Flow 430HP kit, Edelbrock Intake manifold http://www.summitracing.com/parts/edl-7109 , 58mm TB, CAI, Custom headers and complete exhaust, no cats, 383 stroker (or maybe 396 stroker) I can achieve 500HP crank.

I know for Le and Ai, but I am from Europe so it is a little complicated to do that from here

The best way for me is just to buy new parts and put them together at my place.

 

I just read this article: LT1 Cylinder Head Comparison - GM High-Tech Performance Magazine

If I understood it, AFR heads which they used are AFR 1031

http://www.summitracing.com/parts/afr-1031/

Cam is 280XFI, but I can't decide which one of these, I think first one?

http://www.summitracing.com/parts/cca-08-467-8/
http://www.summitracing.com/parts/cca-12-467-8/

Also, these heads require stock LT1 inlet manifold (Not compatible with self-aligning rocker arms., designed for use with Generation II LT1 intake manifolds only.) , so Edelbrock LT4 IM is not in the game, if I understood it correctly.

Can I use this rocker arms with this combo?
http://www.summitracing.com/parts/tfs-31400513

Regarding gasket set, which kit I can use because I don't see on Summitracing that there is set for 383 ci, so can I use set from Trick Flow 430HP top end kit?
http://www.summitracing.com/parts/tfs-31400911/

Also, pushrods I can't buy at the same time, first I need to measure length, OK?

So, if I am right about these parts above , which stroker kit do you recommend?

Thanks a lot in advance.

 

Oh yeah.....don't base your purchases off the magazines articles. Generally, the parts they 'test' come from the sponsors of the magazines and the 'winning' parts may not necessarily be the best parts available.

Use magazine articles as a general education tool, but always do more research before making actual purchases.

If you're budget is unlimited then why not go SC or turbo? That will get you over 500. Or go with a Golen engines? They make a 396 good for 550 hp which should get you about 500 rwhp. They already did all the work and all you got to do is install it.

 

If you're budget is unlimited then why not go SC or turbo.......

He's in Serbia.

Regardless as to his budget, he may not have the proper tech support over there.

Or.....maybe he just don't like forced induction.

KW

 

You are right, I need some combination just to buy and complete everything here in Serbia. So I am not interested in LE and AI and off course, don't want to throw money without a reason. 500HP crank is enough for me and I like NA engines, so SC or Turbo is not a option.

I asked about some combinations a few posts before, so does somebody have comments regarding that? If I can get about 500HP with these AFR heads and other parts they mentioned in test, that's good enough for me.

Also, what I need to consider regarding 383 stroker kit in case I decide to buy these AFR heads combo from magazine test?

 

I'd follow KW Baraka"s advice about contacting Callies and getting one of their rotating assemblies. The only reason I went with scat rods is I am on a very limited budget. If I had unlimited budget like you, I would have gone all Callies rotating assembly and tried for 500 flywheel hp also.

 

The AI/LE route is no different than any trickflow or AFR head shipping issues, except you pay $250 core charge for new stock cores. I believe if you order AI or LE trickflows there is no core charge, pair that with a custom cam, forged rods, -5cc forged pistons, stock crank, get your compression between 11.5-12.5:1 and you'll be in the mid 400s to the tire. Save the $800-1000 on a crank if yours is salvageable and spend it on better top end parts.

 

OK guys,

I decided to buy AFR 1031 with 280XFI

http://www.summitracing.com/parts/afr-1031/

but I need your help. Which 280XFI cam is appropriate for 1993 LT1 Camaro engine?

Retro-fit: Designed for early non-roller blocks. Requires thrust button and wear plate.

08-467-8

Would've been better of going with AI...... :lookleave:

I hope.....at least.....you told AFR that you wanted 54cc combustion chambers on the heads.

KW

 

Thanks a lot, I will buy Edelbrock LT4 IM for these heads.

http://www.summitracing.com/parts/edl-7107/overview/make/chevrolet

Are these roller rocker arms good choice for this heads/cam combo?

http://www.summitracing.com/dom/parts/cca-1418-16

That's whats recommended on Comp Cams site for 08-467-8 cam.
http://www.compperformancegroupstor...oupstores.com/store/merchant.mvc?Store_Code=CC&Screen=PROD&Product_Code=1418-16

 

Get full roller rockers instead of roller tips. Ultra pro mags would be good, NSA with guide plates, hardened push rods, and 7/16 studs

 

You mean on something like this?
http://www.summitracing.com/dom/parts/cca-1632-16/overview/

What do you think about this 396 stroker kit?
http://www.summitracing.com/dom/parts/esp-12113030/overview/make/chevrolet

What do you think about this 396 kit and heads/cam combination?

 

If I were building with money no object, I'd go with a shaft rocker setup. Much more stable than any stud mounted rockers. Price is what keeps many people away.

 

I would too. But again.....there's that matter of having the proper tech support, him being in Serbia and all....

That's why he'd do better going with Advanced Induction or Lloyd Elliot.

At least if he went that route, he could have THEM install the shaft mounted rockers.

KW

 

I don't get why you'd buy $2000 non cnc afr heads, a kinda crappy $300 off the shelf cam, and a worthless $500 edelbrock intake to be lucky to make 400 at the tires when you can buy AI ported trickflows and reuse your stock manifold and get a custom cam for better street manners and make 450+ hp for less money.

 

That setup give 516HP,
LT1 Cylinder Head Comparison - GM High-Tech Performance Magazine

 

516 is 423rwhp with 18% drivetrain loss through an auto, pretty weak for such an expensive combo, the same could be done with an LE2 package or AI190 package or another shops equivalent head/custom cam package. The real limiter is that xfi280, it's not a big cam, has wide LSA, and slow ramp rates compared to what can be cut for you today. No doubt the 195 race cnc AFRs are a pretty good head, but that cam is NOT ideal for almost any setup. The AFRs wouldn't be bad if you reused your stock manifold, but having to drop $500 on an edelbrock manifold that has been proven to LOSE hp due to the small plenum volume makes the AFRs not worth it IMO.

 

..........The AFRs wouldn't be bad if you reused your stock manifold, but having to drop $500 on an edelbrock manifold that has been proven to LOSE hp due to the small plenum volume makes the AFRs not worth it IMO.

The AFR 195'S are LT4 heads. His stock intake manifold is a LT1.

When he bolts the heads and the intake, the ports will be misaligned (unless the heads can be milled to lower the ports)......there will be airflow obstruction.....and thus, power production will be limited.

Also.....in milling the heads, the combustion chamber size will be reduced. This will change the compression ratio by an undetermined amount, and who knows what the impact to THAT would be.....unless he has a machinist who can achieve about 54cc chambers after the work without ruining the heads.

Like I stated earlier.......he'll need a LT4 intake......OEM or the Edlebrock.

KW

 

OK, I can reuse my IM if it's better, that's not a problem

I have T56, so drivetrain loss is much lower than through an auto.

 

Yes that is true, but my point was your still giving up 50hp...
