Hi! Anyone has a 351 cj engine like mine? I would like to ask what main jet and secondary jet size do you use? I am also interested in the power valve size and the secondary spring color. I have a 600 Holley vac sec carb. The engine is near stock. Headers, Performer intake, Pertronix ignitor.
The stock jets and powervalve the 600 came with should be pretty close. Unless you're at a higher elevation. The jets are 66's, the Powervalve is a 6.5
