360 magnum. 1 piston lower in cylinder??

OP, do you already have the EQ heads? If not, then look at the Aluminum Edelbrock Performers..... larger intake valves out of the box, and less likely to detonate with the AL. If you have the iron EQ's, then you are probably gonna want to select the cam to keep DCR below 8.0. Either way, you're gonna need to be careful on the tuning.... it certainly can be done.... I've run 10.3 on iron head with quench, but had to be careful on tuning the ignition timing. You don't just slap in any distributor and set the idle timing (initial timing) where you please and get away with it.
