Default Build me a SB that can handle 900hp..

Well my main question is will i be able to use a stock block? or will i have to go r3? this will be a turbo motor and 900hp is on pump gas, more on race gas.

Which rods?eagle says good to 800hp + but whats +? 850? i have to hav pistons made anyways so thats not a problem.

Well i guess just rods and block is all i need to know, any other issues?

it will be a 4in stroker, but piston bore depends, on stock block, or r3, if R3 then iwill go to 4.18 which will be a 440.

It shouldn't be hard to make 900hp on pump gas, there are a handful of phords and chebys making over 1000hp on pump gas with smaller motors (ls1's and 351's)

I wouldn't mind keeping my roller cam 318 block and just making a 390, hell even a 318 with a forged crank, i have seen 302's at 900hp.

I already have my turbo (holset h2d) and my headers (truck stanless steel
headers) also going EFI with a megasquirt system. (already have)

This is going into my 73 scamp and i would like to see 9's, i really only need 750hp. but i want a short block that can handle 1000 incase i want to upgrade the chassis.

Thanks
Steve

900HP 302!?




Lots of money, that is all I can say, and, use a RB, I would think it would cost more to build a LA.

i don't want to go big block, plus if i can make a 440 la why go rb? the la is going to much lighter. I guess ill have to try to buy my dads r3 from him, along with the backhalf kit!

r-fish; Speak to Carrillo or other serious makers.

RF\Ahhhh, don't we all. Good luck in the search for all you need. Wish I could be of serious help. Haven't been there, but look very foward to what you do and achieve when you fire it all up.

Take tons
Thanks

Default why build

IMOP after the NHRA, IHRA season ends go to the back of National Dragster and buy a supercomp motor thats for sale most of them will be all set up with new rings and bearings and for the price of some of them you couldn't buy the pieces, machine work, labor etc for the same $$$ then sell for.

When PRo stock truck died a couple of years ago,Patterson Engines were sell the P5-R4 motors for less then $15,000.00, you, we all of us couldn't build it for that money, 980 HorsePower.

Just IMOP.

Do you plan on making your horsepower with lots of boost or lots of rpm? It will make a big difference in what you need and want for components.

Well i guess im going to buy my dads block and crank, R3 siemese bore and a forged 3.31 crank. now just rods.....

well i would think both rpms and boost but it should peak around 6500 or so and not fall off at till over 7000.

Should i still bore it to 4.18? i would think it could only help with 14psi.

If you really want to play with the "local gang", purchase a used, obsolete Nascar Truck or Busch engine. With good carbs, you can get 850+ without turbo boost. If you want to go further than that, then go to the turbo. You will need to have the roller cam reground to fit turbo specs and change pistons, but that is minor $$$ compared to the overall cost.

You will need to set up a dry sump system---they have no provision for wet sump.

If you purchase a used Nascar engine, make sure you buy it complete!

There is nothing nicer than a 10,000RPM street engine!

They are making LOTS of power from the LSx and even now the Gen3 hemi's.

Just wondering how this turned out.
He must have the newest technology built into his engine and have a wod of cash in his pocket from his business.
