Sorry for another build question but I have been out if the engine scene for about 2 decades. I currently have a 72 with a 454 in it. Looking for a good suggestion of aluminum heads, roller cam and pistons to get me to 500hp. Need to be able to run pump gas, (I also have E85 available) and looking for a big lope cam. I am using a 5 speed Doug Nash tranny currently. Want something good without breaking the bank. I was looking at this 496 kit, any comments on this one?

You'll get more than 500 hp with this set up.

L88Plus

ProComp???
Do a little bit of research - most consider it to be low-end Chinese junk.
If you're going to go with a cast crank, use Scat. They also make a rod that they call "Procomp", just an unfortunate name. It's the best bang for the buck and you won't have to worry about cam or block clearance.

I would suggest looking for a top end kit good for a 454 but still capable for a future 496. You can easily get 500hp from your 454, and be able to do a 496 if/when you want more power.

labhound

Good suggestion, Edlebrock has a top end kit that claims 540 hp, it's available through Summitt Racing for a little over $2k.

I would check with Chris Straub to see what he can come up with and compare the cost to the Edlebrock. Other good sources are Eric Weingartner who just built me a BBC 477, and Mark Jones at Vortechpro performance.

The Edlebrock top end with a custom roller cam, would be a good middle of the road option. Good luck with your build!

i agree on the crank the scat is probably a safer bet . i am more enthusiastic about a forged crank tough.
I've used pro comp stuff with good results but a crank is a different animal, even with testing you could get an defect that could get expensive.
there are good heads available and most will get you to your target, 500 h.p will be easier than falling down stairs. and a custom ground cam is always a good idea.

Got a link?

You can make 500HP with a 468 and good set of AFR265, hyd roller with a soild pump gas build using your crank, a set of 6.385" rods and a set of flat tops for a pump gas build.

No, You will gain 0 HP. Might gain 30 with the 496 upgrade. Crank, rods and pistons get you nothing unless you bump compression. Need heads, cam, intake exhaust, correctly matched to gain power. Intakes on the Edlebrock top end kits likely won't fit under the hood.

In addition to the stroker kit I will be going with a good set of aluminum heads, roller cam, etc. Right now my 454 is just bored .030 over, cast iron heads (ported & polished, stainless valves, pretty decent cam (not sure the lift), etc. It makes pretty good power, need to put it on a dyno. I want to go ahead and go to a roller motor.

If your going 496 (4.310 bore) go internally balanced and forged. You only get one shot, well worth the $600, already balanced. There is NO replacement for good heads. You will need a neutral balanced flywheel. I got one for $30 plus shipping, you will need to sandblast it. This combo will be close to 600 HP and rumble, yet pull real hard from 2000 to 6000 RPM. Great match for your 5 speed manual.
Check hood clearance vs current intake. Might have to use this one but it will cost you some power.

Fast, cheap, durable. Pick 2

I would leave the stroke alone and increase bore for a 468. That is not the popular thing to do, but why get rid of a 4" forged crankshaft? Mr Straub's suggestions make a lot of sense, IMO.

63mako

The thing is he suggested new 6.385 rods, new forged pistons. On top of that it will need bearings and rings, crank will need to be turned or polished. That crank has been through 2 builds. this will be the third. Time for a new balancer after 40+ years. How much will those parts and labor cost? When you change pistons and rods does the 454 externally balanced weight at flywheel and balancer still balance it correctly? And he still has a 4"stroke externally balanced. Add up the above and compare to $1585, all new parts throughout, bigger stroke internally balanced. You more than anyone gets this Jerry.

Lots of options, thats for sure! Right now I am running an Eldlebrock Torker II intake with a Holly, L88 hood and no clearance issues.

RickyBerg

I have a 454 (no overbore) with Chevys stock forged crank and 7/16 rods.
All balanced and well put together.

The camshaft is the Comp Cams Xtrem Energy 11-432-8
http://www.summitracing.com/int/parts/cca-11-432-8

Pistons are the Icon Premium Forged IC782
http://www.summitracing.com/int/parts/uem-ic782-std

Heads are AFR 315, ordered direct from AFR to get them assembled with their softest springs to fit the camshaft.
http://www.summitracing.com/int/parts/afr-2000

The intake is a Holley Strip Dominator and the carb is a 4150 Holley 780DP.

2-1/8 Hooker Supercomp hedders.

This setup gives me fairly strong and drive-able engine that pulls just fine from 2700rpm and up to 5900rpm and 547hp that fits under a stock L88 hood.

I am not saying this is the way for you but it may give you some perspective to going big CUI.

To reach 500+ HP and still have a lot of torque is no problem even without over boring and/or stroking the engine.

63mako

Lots of options!

StraubTech

The Nash tranny is going to take the torque and 496 is going to produce. I would stick to a 4 stroke combo and either use the crank you have or get a new one. At 500HP your not going to hurt a GM crank.

flyinrazrback

Anyone use Patriot heads? Decent price for a set.
