Boost Build Up/Higher RPM

Bore/stroke ratios:

305 - 1.07:1
383 - 1.05:1
350 - 1.15:1
377 - 1.18:1

aight, I was a little inaccurate on the price but it really wouldn't be a whole lot of a difference in price between a gen1 and genIII to build a turbo engine, the difference in price would be more than worth the technology you'd gain, mainly in the heads and valvetrain but also the oiling system and the EFI.
either way you've got to build a short block, get aftermarket heads(maybe not with the LSx? definitely for the genI)
I'm not saying you can't make power with a genI, just saying that the genIII is a LOT better platform to start with and the price isn't outrageously different anymore.

I just bought an '05 6.0L/4L80E with all the accessories, sensors, harness, fusebox and computer for $4k, it doesn't take that much work to get that thing to 500hp.

he's talking about getting a TPI 3rd gen which means aftermarket computer, already mentioned F.A.S.T., that along with a good efi intake is going to eat up a majority of the price margin. sure it may still be cheaper but not by much.

ahh, I see, how square the ratio is for high rpm. Clarrified but he didn't say anything about going TPI. He asked about going hydrolic or solid and TPIs are what started the rollers off at GM. I just figured he was talking about things in general. He can easily go with a carb set up and fo other efi I know for sure someone also makes a compressed air set up for turbo lag in drag racing applications.
