Re: 1971 350 question

I used to run a 270 advertised duration cam in my 79 C10 with stock heads and pistons. I have no idea what the .050 duration was now. I could not get any traction with that truck. It would just spin tires (no posi). Ricers would easily smoke me at red lights. I threatened to put some big mud tires on it to see if those would spin so easily. I didn't get the chance because it floated the valves and bent one. Sometimes a 270 cam can still be mild and torquey.

Those Edelbrock performer cams are about 220 @ .050 and I think those are very mild. I never disagree with Geezer but he seems to like cams a little milder than me.
