Timing

More initial timing should help. BTW, how do you like that Lunati 703 cam? I planned on using the same cam in a 340 build. 65'
I really like the Lunati cam a lot! I wish I would have put it in the first time. The car has much better street manners. I have power brakes and A/C and both work just fine. The Comp cam wasn't happy when the A/C was on at an idle. I was on the fence about using the 702 or 703 but I'm glad I went with the 703.
