I'm installing a 91 4.3 V6 into my 80 Luv 2wd. I'm changing the heads to the Vortec from an 01 truck. Will my stock roller cam and lifters work alright with these newer heads. I'm going with a carb setup and eliminating the TBI setup. What distributor will I need to run an HEI unit.
This I have a little experience with..
I run a 91 4.3 with 97 vortec heads. Edelbrock makes an Intake just for this. #2114
Cam is the one that matters... I think you're perfectly safe on stock cam. I'm running a compcams cam and never used stock with this combo so I can't be sure but none of that changed with the heads except where it meets the timing pulley or something like that.. compcams had something about it on their site if u want to confirm parts interchange.
Distributor is basically whatever year engine you have. I have used a couple various eBay HEI ones and all worked. Going to one without internal coil because the ones with a built in coil are bulky and I have a brand new MSD coil collecting dust.
Great looking truck too
