Attn: Ede Need 4.3L build info.

I'm trying to build a 4.3 for a 91 full-size truck, that originally came with the 4.3. I want a real torque monster. I was wondering what parts you used (heads, cam, rockers, internals, etc.), and what your induction is. This is going to be a daily driver.
Thanks.

Your best bet is to post this in tech/general engine. I have one of those 4.3 full size trucks also but it got a beef injection. I still dont know where GM got off putting a 4.3 into a full size doesent make sence to me.
