Hi Guys, I'm itching to get more power in my '04 Z71. Here are the different scenarios I'm considering. I'd love to hear your experiences doing any of them, or something different. The key issue is I live in California, and I want to be able to smog it without a headache.
1) Bore existing LM7 iron block to LS1 (3.898 in) spec, new pistons, LS6 heads, LS9-grind cam, Magnacharger TVS1900 Radix blower.
2) LQ4 or LQ9 long block, Maggie blower, shut the hood & call it a day
3) LQ4 or LQ9 short block, AFR CARB-legal heads, LS9 cam), Maggie blower
4) Gen IV LS3, Maggie blower
5) LSA Crate engine (If I can pull together enough money)
I know I'm going to have to beef up the 4L60 for it, but if I'm having the engine built outside the truck, might as well get a built 4L60, and put them in together.
Thanks in advance for your feedback and experiences.
