Best 383 combo?
What would be the best combo for a 383? I was thinking a stock LS6 block, with the eagle crank, and forged rods/pistons. Would that be a good combo? I would run a fairly large shot of Nitrous(200-250) on it. Also, I would like it to either be very low 10s or high 9s on spray. What do I neeD?

not flaming your idea because it can be done, there are packages on the market to do it but I would buy and Iron block as opposed to aluminum for stroker motor. I would be affraid of destroying the block with too much hp/tq.

and, why LS6 block? why not LS2 block instead? cost more for LS2 block? or do you already have an LS6 block? then I guess I could see why. I will be curious to see what people come up with for possible combo's that could reach your goals.
but, I think you need to give some more specifics. what kind of car is this goin into? weight? Im goin to already assume it'll have a cage, built susp., yada yada.

I would keep the aluminum block. They are good till around 1000 hp then you have to worry about flexing. As for Eagle while the kits they sell are decent they do require a lot of machining for balancing. If you can afford some better components I would suggest getting them. You will also need to use ARP studs on the entire block. Make sure you get some decent rods with ARP bolts as well. As for pistons all of the major forged companies are decent. You will need the other supporting items such as a good flowing set of heads, exhaust, and intake. All in all I would be prepared to fork out around 7,000 - 10,000 dollars if you want the setup done properly.

The reason I was thinking of LS6 block was because I can buy them used for fairly cheap. I would also be selling the engine out of my 2001 Camaro Z28, so that would probably net like $2000 or so. The car has a lot of suspension components and a roll bar. The cage I would probably get later on once the engine is in place. Same with the nitrous.
Would going with the 408ci short block from TSP be a better idea? I was thinking either LS6 intake or waiting and then upgrading to a FAST 90/90 setup in the future. As for heads and cam, not sure on those. Probably either a 6.0L head or LS6 heads with a good nitrous cam.

408 is not a bad choice. The iron block is durable and it should take a lot of abuse. I would get the Fast 90 right off the bat especially if you want to spray the car. I think the cubes and the nitrous will easily tax the ls6 manifold and TB. As for head I do not know many people using 6L, but the LS6 is a great head when ported for big horsepower.

I have been tossing the idea around of having a 383 built from my existing engine block.
However, I'm wondering if it would be cheaper to go with something like TSP's 402 long block. I have not looked into this too much yet, still thinking about it. but I'm really not sure you can beat that price ($7400) for a stroker motor, a set of ported heads, and a cam.
have you looked into this route yet?
By the way, it would be going into a '97 vette.
