Is this the cc503 cam and do I have a concern with use with the 96 vented opti spark? I read today that there is a cam difference with the vented opti spark in the pin length and maybe another hole or other difference on the forward end.

Comp Cam #07-503-8
Specs: LT1 (xr276hr-12)
ADV 276 281
DVR@.50 224 230
LIFT .503 .510

 

yep thats it, and you should be fine with the length, but give thunder racing a call theyll help you out

good luck man!

 

Thanks, thought so but wanted a second opinion.

 

Always make sure the dowel pin is the correct length.

 

The pin should be 0.615-0.620" long.
