Looking good, Russ! What sort of boost numbers are you planning on running? Are you going to keep it low for longevity's sake? I think you'll be running anywhere from 800 to 1000 hp, depending. Did Blair mention where he thinks the limit should be for boost? I have no idea where the limit would be for an FE. For a stock block, the crank webbing would be the weak point. But for a BBM block I'm not sure if it would be the lower end or the clamping force on the heads, with only 4 studs per cylinder. You're in new FE territory, as far as I'm aware.
