i am trying to do this on stock heads. Mainly because i am doing the head work myself as well as tune so those will be free labor

Like stated, 3 grand isnt even enough for the top-end of a 500rwhp build.

I scrounged, bought some stuff used, and searched forums before I bought anything and still broke 10 grand just on the engine so far. I do not expect over 500rwhp through that setup, and that is with a budget more then 3 times larger.

Now, if you want to spray, then you can start making a list .

what cost so much ?? the cam,springs,studs,gaskets?

The reason people are saying it is so expensive is becasue they are budgeting heads to meet your goal. I know that you plan on doing all of your own head work to get 500 HP but if you look at things "realistically" there are vendors on this website that have countless hours in research and development. They also have equipment such as flow benches, CNC machines, and dynos at their disposal not to mention a large number of followers who share the same passion for LT1 perfomance. There is not one company who can sell you a set of their top of the line heads and guarantee 500 ponies NA. That being said, and I am not trying to be a dick, I do not feel anyone can make that kind of power out of a set of home ported heads.

I thought I posted a link But Larry makes 457 with a mild HR cam and ported stockers on a stalled A4 with a S60 rear end. With a serious SR cam and more head work I think he could get damn close.
But like said 3k will not even come close

I am not saying that it can not be done by any means, I am just skeptical that it can be done on home ported heads. Who ported Larry's heads? I doubt it was someone's first or even 100th kick at the can at porting LT1 heads. Now I don't know how well the OP can port headsor how much experience he has. He may be a shadetree guru and if that is the case and he meets or even comes relatively close to his goal at the flywheel I will gladly eat my words.

i have all the machines to get it done at school and dyno as well I know complete heads are expensive but with that out of the way wht kinda money wuld i be lookin at ? Thanks for the response guys i am open to suggestions but no juice

Yeah Im not sure the OP can do it, but I think it could be done(we know nothing about the OP).
Larry had a local guy do his heads and I think runs LSx valves or something with a mild LE HR cam

Z28reggie

thanks for the vote of confindence lol well i will have pros helping anyone know about the costs of the other stuff minus heads

Z28reggie

going to bed but if someone could give me a round about number i will be appericative (sp?)thanks again guys maybe will shoot for 400 wrhp but it would be nice to get more lol

500rwhp can and has been done with ported stock castings.

The budget to do so is WAY over $3000.

I think the OP needs to know Summit is NOT the endall source for parts, they are the walmart of parts houses, they have a LOT of what you need but sometimes you need something more specialized.

Ricks car does not even remotely fit the description or goal of the OP.

I still am firm that with a stock shortblock like the OP stated, and the rpm limit implied from stock cube/stock computer, there is no way you will see 500rwhp through a stalled auto on ported stockers...period.

A 7.2K rpm 383 with some of the best CNC'd stockers around a huge solid roller? Sure. A 6300rpm 350 and an off the shelf cam? No chance in hell.

i agree, using ricks car as an example of possible results is ridiculous

op 400 at the wheels with a H/C package and full bolt ons is attainable. you have to remember that LT1s arent high horsepower motors. its the way you set them up that makes them fast. you have to get the right components to work together to be fast

Wicked94Z

the reason you don't see a lot of "high" horsepower lt1s is mostly everyone builds their motor around the 7200 rpm pcm limit and stock style intake manifold. Thus you see a lot of small cammed builds peaking around 6300-6500. RPM is horsepower. In a race motor, a 300+ cfm CNC'd AFR, Dart or Brodix head is going to be paired with a tunnel ram, a 270 @ .050 solid roller with .800 lift and is going to make 700+ hp at 8000 rpm. Granted a 5500 stall, 4.56 gear and 30 inch tire goes along with it, but there's no reason to say LT1s aren't a high horsepower motor when there's plenty of small cube SBCs out there running 9s.

AFR 227's, competition ported
Single Plane
Fast XFI
BIG Solid Roller
1-7/8 headers
Motor balanced and put together RIGHT
Vacum scavenge pump in the crank case
12.5:1 Compression
and ALL the other supporting bolt ons

and you could probably do it through a locked converter.

You could also substitute said heads for some BAD *** 18 deg SBC heads and have them converted, might make your goal a little easier.

On a budget of 3k, ahhahahahahahahahahahahahahahahaha

Just a refresher to what YOU said.

I never implied a 6300rpm 350 would do the job, and said the OP needs to think outside the Summit box which implies his off the shelf cam choices need not be considered.

Over 500rwhp through a stalled auto NA on a stock computer is possible too. Again not with a stock shortblock, but IS possible and has been done a few times even with the GM intake.

The OP wanted 500rwhp through a stalled auto on a stock shortblock with ported stockers.

Not going to happen, and has nothing to do with Ricks car.

@ $3k..better bring like 3 times that..
