So far I like the Chevy 4.3L V6 over the Buick V6. I think parts will be easier to find and I can switch to a 350 easier. I don't want to mess with EFI though because I don't want any computers in my rig. I heard that Edelbrock (I think) makes a conversion kit with carb.
One worry though, after reading some posts on this newsgroup. Will this engine run okay with a carb, going from 2000ft elevation to
9000ft? Do they really need to be adjusted every 2000ft, or is that just for "top" performance. I've had my current 4-banger with carb at elevations from -100ft to 9000ft and it runs the same either way (like crap, j/k it actually runs pretty well).O-ya, I'll also have to change the distributor. I understand there is also a kit for this. I guess a lot of race cars use these 4.3L V6s, Vortecs, but change to carb and sawp dist. which removes the computer as well. Guess I can check with the hot rod shop, but does anyone have any links with details or parts for this swap?
