I have a 69 340, .030 over, 10 to 1 comp, stock x heads, running elderbrock rpm air gap and cam is going to be a Comp nostalgia plus 20-674-4 ADV. DURATION 292/299 VALVE LIFT .508/.508. My question is i have a holley 650 DP is that enough for my car? Or should i go 750? Just Rejet to bigger jets?

-Not drag racing just a street car, if anything might autocross or something

Shesaid has told me to go bigger but looking for some other .02 cents

Your 340 is close to mine, Isky 505 cam, stock 340 heads with a little work, 2.02/1.60, I also have a 4-speed, 4.10 gears. I have a M1 intake with a 1" Super Sucker carb spacer, I run a 650 DP and it works great! I have messed with the jets a little from time to time, I run it on the street and it does see track duty, works nice when driven hard I have always wanted to try a bigger carb but I don't think I need to.
