If you want a take no prisoners car 350w ported 305 heads . I have a slightly different Isky cam in mind but you must use long tube corvette headers, free flow exhaust (open headers) and a 3500+stall or the power will not be realized.
Isky cam #201534. Install on a 100 to 102 intake C/L. needs 10.5:1 cr. (flat tops)
rough idle, locked timing 3500+stall hits hard from 3500 up.
I have a even bigger Isky that is used with a 5000 stall race converter, single plane or tunnel ram 10.5:1+++ and 4.56's
It does not take wounded prisoners. 7500+rpm
