HP potential for a 9.2:1 360???

I have the same combo. dyno numbers were at 423hp. 4 valve relief speed pros, stock rods and crank, 63cc ede heads, comp xe284 cam, ede air gap intake, 750 holley street hp.
Very nice.... I dont want him to have that much HP. Id feel awful if the low budget 360 was rite up there with my not so cheap 340. LOL!! JK
