A great old school radical cam is the Isky Z-60 grind.

Go with a comp xtreme energy cam similar size or a comp magnum cam. You will get a little lopey idle but still get good vacuum. If all else fails get the comp thumpr flat tappet cam but the previous ones will give you better horsepower and torque. It will give you a nice choppy idle and not be too much problems. If you go with anything bigger expect some carb tunning headaches.

Use a Comp 280 mag. It's tried and true, and it has a rumpety idle while still being streetable.

You could do it the cheap way,put a manual choke on it and pull it out a ways and it will sound choppy then push it in when you want it to run decent.

I guess with a manual trans, good gear and a light car I've never been afraid of to radical. The only cam that sounds better than a Z 60 is an L-88. JMO
