I'm wondering if it is worth the trouble.. I have a 408 that is fresh not assembled has steel crank and kb pistons ( not forged ). From previous experience it should come out around 9.5 comp with the heads I'm using .

This combination made about 450hp without the blower . I'm wondering if I can get past 500 with the little blower. I have it already with all the parts to install it . I'm going to put it in a 76 duster with a 904 9.5 converter 4:10's and rip around town in it and what I'm really looking for is some numbers on the mobile chassis dyno.

The cast pistons are a worry I can always add race gas for the dyno runs!
