i have a 96 s-1 blazer with a 4.3 converted to carb. it has a big 4brl, and it floods out, it needs a 2 barrel. whats too big whats too small. tis nto a race truck, just a good lil runner. what size is a good carb for a 4.3 use thanx...
Dude, 600 is WAY to big for a V-6. I'm running a 450HP 355 and using a 770. I would call up Holley or Edelbrock and ask them. I'm getting ready to possibly do the same thing with my old 4.3 that came from my blazer. We really fucked up the harness jerking the motor out and I think it'll be easier to just convert it to carb
