so as you ready the title i have a holley 4160 double pumper 650 on my SBC 400.
it is balanced and has edelbrock aluminum heads and speed pro pistons running about 10.5:1.
dual plane performer rpm air gap intake. headers and 3.73 gears.
it has a crane mutha thumper cam in it.
it runs 12 inhg at idle and about 5-6 inhg in gear.
so i changed the power valve to a 3.5
should i do any jetting? my car always smells rich.
i am at 580 ft above sea level and really only drive it in the summer.
it has 67 jets in the front 73 in the back. same as stock.
holley tech info says that factory jets should be good from 0- 2000 ft average of 70 degrees.
any thoughts from those that are expert carb tuners? i have read everything that i can get my hands on for holley tuning.
appreciate the pointers.
