My 71 Demon

When we bought the car it came with two cranks, and an extra set of +.030 pistons. I took the block, heads, pistons etc up to the machine shop. We decided to go with a highly recommended shop up in Sanford Fl. for all the machine work as I would be doing all the build up. We called Comp Cams to get all the info we could for choosing a cam. We went back and forth about doing different types of cams but we decided on going with a pretty tall hyd roller cam. This was agonizing to be honest. With the all the options and experts telling us what was good and what wouldn't be street-able with power brakes blah blah blah. In the end we took a leap of faith and went with Comp Cams recommendation for what we want to do with the car. Cam P/N 20-811-9 with .538/.534 lift. Comp told us despite the life, the duration would keep our vacuum in the good.
