I have a 74 2 bolt main chevy 350 out of a impala. I have torn it down for a rebuild. I have a 79/80 2brl aluminum intake and 883 heads that will get ported to match. I will probably stay with stock valve springs and not turn anything into a roller. I do a little racing and that is what this engion will be for. Fuel econ is not something I will be interested in. I am trying to find a cam that will work with the carb/intake/heads, but still be in the power range of 1200-5800. Personally I want a good low to upper torque along with good mid to upper HP. I was looking at several cams that tend run generally around that rpm range and the lifts run between 442 and 480 ish. I run probably around 12 times for roughly 10-25 mins each time. I am looking for something that will stay as cool as possible, probably stay around the 9:1-10:1 comp range. Any help in this decission making process would be greatly apreciated. Mainly looking to bounce some ideas off of people.
