Holley Jet size

Thanks for the response Gives me something to to start with. I'm no pro but will will start 1st checking the power valve . 15" vac. #8 valve.Then go from there with jetting. I am now definitely too lean with current carb. which 1st leads me to think I had a vac. leak. But don't think that's the case as 15 is about right with stock ( I think ) cam . If I had $$$ I should have upgraded cam (just replaced lifters). All I did was inspect measure for wear and re-used.Motor sounds sweet with 160 psi Comp. check.
