FIFTEE3 have you changed the getting at all? You running a stock cam?
Stock cam. Jets are as shipped from Tom.
I cant see any vac advance hooked to your carbs. What you using then? Also what fuel pump are you using?
My distributor is HEI mechanical and vac. Performs mush better without vac advance. Fuel pump is standard Chevy pump. Pumps about 4psi. Really don't want more than 3-4 for these carbs.
Try Joe H's tip. Sounds like a good one.
