The carb, cam and compresion are good. The intake should be changed out for a decent dual plane. You'll gain alot of torque and run better/faster with it.
Even a factory iron 4bbl intake is good seeing that the cam is small.
Ok so the Edlebrock streetperformer single plan is out.....I have a new Edlebrock performer dual plan here is that any good for what I want to do ???
Again I only have the 600 Vac Holley for now but will upgrade soon I was thinking that I would start with changing the 63 jet to 67 & see if that helps yesterdays test run the car seemed to lack top end just wouldn't rev up quickly...
Also what timing would you recommend I setit at 10 BTDC at the moment & it seems to start & run fine no run on or pinging.
