If the heads flow in the 240-250 cfm range, and with over .600" lift solid roller camshaft, and ported intake, with the 10.5:1 compression, the good ring package, etc., should be in the 1.4-1.42 hp/ci range. My little 303Y with similar preparation, head flow, .600" lift solid lifter engine made 390tq/463hp with 10.45:1 compression. No reason the 352 can't do the same. JMO, but it should be a good chance to see what a blueprint can do with a forgotten engine. Joe-JDC
