Timing Question

[429bbf]

350 chevy ,small cam,carb 17082213 my question is what should the initial timing be set at? i dont work on chevys.iwork on chevy carbs.the air cleaner says 4 degrees . this is a 1982 1 ton chevy van.the engine is brand new i just put it in.when i was setting the timing it seemed to like about 10-12 degrees ive got the idle screws out 3 turns and the apt about 4 . thanks in advance for some answers.

I would say that 10-12 degrees would be just fine. Make sure your total does not go over about 34-35. should be good for a truck/

Hey believe it or not, I am not really a GM guy but actually a MOPAR guy (Q-jets work great on MOPARS), but I do like Pontiacs cause I had a GTO at one time. I have also had a chevy pickup ('77 with a 350) and it liked the 10-12 degrees of initial. Really the low numerical timing was just  for emissions. But that's the way they were from the factory. I've got the 318 in the powerwagon set at 12 degrees FWIW. It is set up similar with the small cam iron manifolds iron intake and Qjet.

thanks for the help i picked up a couple of mopar q jets not sure what to do with them.im a ford guy that likes chevy carbs.

The Mopar Q-jets are really good units. Not set up lean at all like a lot of the chevy carbs. They work excellent on a chevy. I think the linkage is slightly different. Best part is they are somewhat easy to find on a mid eighties dodge van with a 360. This is because no one thinks about finding a Q-jet on a Mopar in the J-yard.
