im have a 94 z28 with stock heads with every bolt on you can do what cam will be the most helpful? dont wanna port my heads i just sold a set of ported heads just want a little more pep

 

CC XE 502 (XE 218/224), it's proven to throw about 340ish HP/TQ at the ground on a bolt on stock headed 1.6 rocker car.

 

If you want a little bigger, go with the XE 224/230 with 1.6 RR. Works great with stock heads. Go to www.cmotorsports.com for info on cams.

 

Have you seen the 224/230 put 343/343 corrected to the ground though?? Plus it's powerband is going to necessitate a higher rev to hit the peak than the 218/224.

 

I have not had mine on the dyno, but I can guarante that mine will. I have raced mu buddies '95 vette that was dynoed at 356 rwhp and beat him pretty bad. My car feels great and pulls hard.

All I was saying, is that the 224/230 is going to give you more hp.

 

Not necessarily on a stock headed car.

I did a search and found the following:

jkipp84's sig: XE 224/230, 2400, 3.73's, Bolt-on's, lots of BMR. Dyno: 326/318 SAE

There's this thread.

Then there's 94formulabz, read his post on the second page of this thread. He made 343/343 SAE, 351/351 STD at the wheels.

I know that's only two examples, but I didn't feel like searching everywhere for more.

Either cam is going to be fine, but bigger isn't always necessarily better.

 

Keep in mind I have an A4. If it was an M6, that number would've been in the 340's.

Either one of these works great with stock heads.

 

Didn't take that into account. Thanks for the heads up.
