When I said straight up on the 375 cam, I meant installed right out of the box, no degreeing. He later had the cam degreed and moved it to 4 degrees advanced. That produced so much low end that the car kept blowing the tires off. Cure was to retard the cam back to where it had been originally. For the record, the 375 cam was a TRW/Federal Mogul/Sealed Power (whichever name they were using at the time) replacement part, not a GM original.

I race a pure Stock zl1 camaro, the exhaust manifolds are the limiting factor in the Cam. Run a 114 straight up, you need to kill low end to get it to leave without blowing the tires off.

Look no further than the L88 Cam. The ZL1 has to much duration for the manifolds.

Btw, I went 6/10ths faster by going to an automatic

Cam Choice..
 

I was waiting for Eric to jump in...follow his advice :cool2:

Well all of this sounds like I need to go with what I have found by looking around on this site and several others. 396/375 cam installed on an intake centerline of 114 degrees which is 6 degrees retarded from as ground by maker. But one above says "straight up" just like the factory ground it. One thing for sure with the 10.3:1 compression and ZL-1 cam, I have not been blowing the tires off. I guess there is just no information on the ZL-1 cam because it is just that bad for a car with stock manifolds. I will also raise the compression ratio to be more in line with a ZL-1. Thanks for all of the help!
