Default Springtime is coming.

Time to get ready for another year, I'm excited. looking forward to fine tuning the engine on the 77 C-3, I'm getting closer on the quadrajet. A 1984 GMC pickup non electric 350 carburator 800 cfm on a BB 402. It should work.

I have an option of using an older ProComp injection system that worked well on a 84 Firebird 383 chevy. I would pefer using a Q-jet If I could, I have 3 good ones and one for parts. they are easy to work on. I installed a AF meter last year trying to get the jets and rods in range. The exhaust smelt rich but when I checked the plugs the porcelain they were white, didn't make sence. I would like to get the AF ratio between 13 and 14 would be good, I should be there soon.
