Mechanical Cam
LOL, your kidding right? I say that because you gave not one detail about anything, so..............
Answer these questions so we (I) have an idea where we are going with this build.
Assuming the car is your screen name;
Whats is the;
Weight of the car
tranny used
rear alxe gears
intended use or what you want out of the car?
tire size
any other performance parts on the car/in a box for the car ready to go on?
Any work done to the motor like a recent rebuild, heads worked on, shift kit in tranny, etc....
With these answered, I'll have a good idea what you have and where you want to go with the car. Then and only about then can someone make a decent suggestion on what would be a good (Ball park) cam for you.
Now, whatcha got going on!!!!!!!
