I was just curious as to what you guys were running in your 383's that make tons of power. I am in the process of building a 383 with the goal of getting into the 500/500 club. I had origionaly thought that I would need a 4340 forged H-beam rods and a light weight piston like the JE/SRP type but after discussing it wiht the machine shop i think I might be over building. I would like the freedom to shoot it with a little nitrous 150-200 shot in the future if I get the bug. My question is do i really need all that expensive 4340 stuff or could I get away with a scat 9000 cast and a decent set of rods and a nice forged piston? I was quoted a price of $4500 for the short block with a moroso oil pan and pump, timing chain and Neil chance 3000 stall converter and a msd distributer. It really is a good deal but i was told i could cut the price in half if i went with cheaper stuff. What should I do?

Check out Beck Racing Engines , their STREET KILLER 383 does 548 horses using the following
SRP/JE FORGED PISTONS
BRE 6" 4340 H-BEAM 3-D CONNECTING RODS
SCAT LARGE RADIUS CRANKSHAFT

Their prices are pretty good, you should call them and have them price you an engine out. Their 355 Street Killer does 508 horses using the same above.

I think a good aftermarket cast crank and I beam rods are fine for 500 HP. Much more than that and I'd look at forged parts.

An ocassional shot of N2O might be OK on a cast crank, but you know how N20 users are --- gee 100 HP sure was fun, I think I'll try spraying 300 . . . LOL. My point is if you are serious about spraying it maybe it would be better to go with a forged crank and some strong rods.

PS. IMO most engine failures are due to a valve train problem (dropped valve, etc) or a machine/assembly error (spun bearings - wrong clearance, etc) or a piston failure. So these are probably the most important areas to spend your cash on. The forged parts are mostly "peace of mind".

I agree 100% with Eric. A nitrous setup is easy to get greedy with, but if you do, go with the forged internals. I work for LPE, and we have built 100s of 383 combinations with the LT1s, LT4, LS1s, L98s and the old style blocks, and cast cranks are adequate for the 500hp range. I just built my personal 383 with some Brodix track 1s and it made 517/495, and it is realitively tight yet. I am going to chassis dyno it as soon as I get it in the car, get some miles on it, and chassis dyno it again (probably next spring) to see where I am at to see what I will gain after a good break in. I can give you some specs if you are interested.
