Convert 4.3L Chevy V6 to carb?
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? |

http://www.edelbrock.com/automotive_..._v6_perf.shtml Carburetor: http://www.edelbrock.com/automotive_...erformer.shtml or http://www.holley.com/types/Street_P...raditional.asp 390 or 465CFM Distributor: http://store.summitracing.com/partde...5&autoview=sku This should get you running. Whatever carb you use, you will need to do some tuning, so I would recommend the Holley, but it is personal preference. The large changes in elevation can't be compensated for by a carb, so you may want to look in to one of the quick change jet kits for the Holley, which will let you swap jets without removing the fuel bowl.

Re: Convert 4.3L Chevy V6 to carb?
Thanks for the links Chris! So do you think that anyone with this
setup, driving up a mountain for a weekend ski trip (for example), would have to stop along the way and swap the jets? I guess I have seen a lot of older vehicles in the pull-outs going up the mountain. c wrote: > This should get you running.

Re: Convert 4.3L Chevy V6 to carb?
Isn't there an issue with Holley carbs and incline or off camber stalls?
