I cant make up my mind.DO I rebuild the 350 and 700r4 I already have or do I try to find a low milage 6.0 and 4l80e combo or maybe the 5.3.The 350 would either get stroked to 383 and be built to around 425 hp or I would do a 355 with around 375 hp.I would have to buy some good heads either way.What do you guys think?

Get a 5.7/4l80e and bore it to 383. Totally worth it. A bit better mileage and much more power. Just my .02

Is your truck a weekend hot rod, or is it a do-everything truck ---

I'd rather have the late model FI stuff for either though, i think, but the small block rebuild would be cheaper in the short run for a Saturday night toy

Depends on your budget.

This truck will be a driver but mostly just in good weather.No matter what it must have plenty of power.I really would like around 450 hp.

Well, it's not tough these days to get any of those combos to 450hp.

6.0L will cost more for adaptation but have nice HP with EFI.

The October issue of Hot Rod has a Crate Motor shoot out in it, includes the 6.0L LS3 as well as older SBC and BBC motors from GMPP.
