Was wondering if this would be an alright choice and still be a DD. Car 84 z28 l69 H.O. Current mods: Holley 670 street avenger, Hedman LT's, full 3 inch exhaust, performer rpm intake. Should have the #416 casting heads. I was looking at these cams. http://www.summitracing.com/parts/CCA-CL12-210-2/ or http://www.summitracing.com/parts/CCA-CL12-242-2/ Wasn't sure if these would pull to much vacuum for a DD and typical stuff like that.

I have the second cam with shorty's, 600 holley, and the rest is the same. It drives fine and plenty of vaccum. I have a 2400 holeshot nitrous torque convertor and could use one a little bit bigger with my 3.23 gears. Kinda lazy off the line but likes nitrous.

Oh, and its in my 305 car also.

The lift clearance was ok I'm assuming without having to rework the heads. Also, have you made any passes 1/8th or 1/4th with that setup, or dynoed it?

Yeah there were no clearance issues. I did have aftermarket springs that had came with my Summit TPI cam set. I have a few threads about my setup.

Nice Thank you for the info. I Don't mind the being lazy off the line. I have a T-5 and I'm not looking to grenade it. lol. I'm sure my 3.73's will help out also. I now have higher hopes for my little 305. I was shooting for 13's but if I can get into the 12's with a 150 shot at the strip I'd be a happy camper.

Yeah with a T-5 and 3.73's it should be better off the line.
