I'm breaking this truck all the way down currently and figuring out power train. Its has a gm goodwrench 350 with 350th trans. It sounds great but is a slug. I want this truck to be FAST. I want fuel injection as well. I see they make fuel injection conversions. Would this combo be worth building or should I just buy a crate motor/trans combo? LS swap? In the process off fixing body so LS swap would need to change trans crossmember and motor mounts. Better to do all that with body on frame. My current thinking is blueprint efi stroker with 700r4 trans. Need to plan a rear end as well. Any advice? LS is what Ive always wanted to do but I feel like it takes away from the nostalgia. Plus an LS would need electronic shift trans and I'm not too in tune with setting all this up.
