I had planned on building a 340 to run IHRA pure stock with my 1969 Barracuda street car. The Crandall track closed, so that plan went out the door. I had bought a custom cam from Bullet for that deal, it was something like 250 degrees at .050" on a 109 LSA as I recall. The old factory spec for the 340 cam was something around 336/348 duration at .000" lift, so that gave a lot of leeway in grinding a cam. Not much different from the regular stocker cams from what I know about them. I also have an old Lunati(c) cam and an ancient CD stocker cam from the 1970s that I was going to try. I liked the idea of Pure Stock since I didn't need to put a rollbar in an original 340 car.
