I have not done a compression test yet, but I expect it's up there. Reringed 5.9, edelbrock/MP heads with 58cc chambers, 212/220 @.050 cam. Idles with 18" HG.
Yeah that combo should make reasonable torque.
However, alloy heads will suck a lotta heat out of the chambers at low to mid rpms, So when swapping to alloys for a streeter, the Scr needs to be bumped up at least a half a point; say from 9.2 to 9.7, just to compensate for the heat loss. I found mine needed a full point from 9 to 10, and then needed more compensation for the bigger cam I chose. And then I found out that alloys run pretty good at 10.5 to 11.5 depending on the resulting pressure. Mine still burn 87E10 at 180psi. And you ain't seen torque until you get to 180 psi,lol.
Once you get her wound up, there is less time to get rid of the heat, and that is when the alloy heads start to shine.
I painted my Eddies in an effort to keep the heat in.
