cam selection
How much cam can I use with a CC carb 350? How much duration, LDA, LSA, lift without upsetting the computer? The cam grinders I have talked to have given some really minimal specs, I figured You guys real world experience would be of help. THANKS!

i think i'd listen to about any cam grinder before i would someone on here. they make cams everyday and ought to know what they doing. especially if you are getting the same or similar answer from several cam makers.

Would there be any way (without nitrous) to get in the 13 with a 350 in place of the 305 and still have the computer hooked up?

sure people do it every day. not too hard to make a sub 14 second 350 with the ecm controls. read the sigs on here. lot of people have their mods and ets in their sigs and you can get an idea what they have and what it takes.

Any cam for a ccc engine is going to be pretty tame. Honestly, I would just ditch the ccc in favor of fuel injection or a honest to godness Holley and put a real cam in it. Granted you will loose the electronic timing and mixture controls but the computer won't be able to support power levels much beyond stock anyway.

The factory does everything you're asking while maintaining emissions legal standards with the 350 HO conversion kit. They use a ZZ4 engine with the original factory carb (recalibrated with secondary hanger & rods), new ECM and PROM, and exhaust mods. They say they got the car into the 13's, and that without headers. If you have an auto transmission, you can use the kit.
The ZZ4 uses a roller cam. Although I'm planning on using that cam in a 305, we'll see if it can pass emissions. I'm betting it will, and it probably has more agressive specs than what you've been quoted by the cam grinders.

Check out Crane Cams Compucam. That's what I've got, and it ain't small.

Thanks for the inputs! I am not looking for anything more than mid to low 13's without a power adder. I plan on using edelbrock's TES headers, the flowmaster force 2 3" system that is on the car now, edelbrock performer intake and cam, and a good set of heads (possibly vortec cause of their bang for the buck), a new chip, 3.40ish gears, and if I can find one (or make one)a dual snorkle intake with my K&N. Think that would do it with a computer compatable cam?
