Anyone have personal experience with ethier the
Isky z35 254/525/108 cam. Or comp cams 306S
260/555/110 cam?

Ethier for me would be in a 440
I have personal experience with the 306 s
In a 454 chevy 290 cfm iron heads 11.0 cr
Made 560-585hp on dyno. 72 camaro screamed to
7000 and was 10 sec ride for all intensive
Purposes.

I like the isky for me due to it's a "557" with
Tight lash and 108
