What spec is it in a cam that would dictate how much vaccum the motor would have? I picked up a dial indicator today at work and I am gonna get the lift specs of my cam soon to find out what the hell I have. I don't have a degree wheel so I can't get everything but I am thinking of getting the performer plus cam when I install my GT40 heads. I don't have a roller block so I can't get the TF stage 1 I want.

 

bump

 

Overlap and events timing (intake/exhaust - opening/closing) + engine CID + heads used.......

 

^^^^ Money

 

How does money have anything to do with it? Yea I know it takes money to buy parts like Joel was listing but it has nothing to do with my question. I just need to drop these low compression 78 heads my motor came with and get hot on installing these GT40's I have siting in my gargae and buy that new cam.

 

I think he was saying that Joels response was 'On the money' = correct...
