What block to use for 383 build up?
Should i use a 93-97 LT1 block or an older SBC block for my procharged 383 build? Are there really any differences or advantages/disadvantages? I'm using reverse cooling converted SBC heads and a Vic Jr single plane. I'm still not certain on a EMU(will probably use the stock pcm since its cost effective and I won't be spinning past 6800rpm) and ignition yet, I'd like to get away from the opti and its "problems" if possible. Also what does the machine work on a 383 cost if I supply all the parts or even install everything myself?

As far as the block itself, the castings are essentially the same as far as strength, etc. But if you plan to use the OEM ECU, it's easier to use the LT1 block and keep the Opti. The Opti isn't so bad, you just have to replace them once in a while.
