A great combo for a heavy truck would be a iron block 346 with forged internals and the Radix....you could run some serious boost (safely) and the end result would be great linear power all through the powerband.

I love having options. Just a few years ago I would have been buying 2 new pistons and throwing it back together. I am feeling more strongly about the 346 than any of the combos.

I'm still a spoiled brat who tends to have a tantrum when I can't have what I want when I want it
I basically saw that I was about to build a motor like I want in the vette. I then stopped and tried to figure out how I was going to top the truck motor in the vette and that answered it for me. Invest the speed parts in the toy made for speed.
It's still going to have 50-75 more hp than the 4.8 due to the cubes and better heads (ported 817's).

317's are 6.0L heads.
I'd like more cubes, even though it would sacrifice boost, but I'm trying to get the most bang for my buck on the concervative side with what resources I have. I think the 346 will be plenty. A hell of a lot better than that damn 293!
