Why would you not look at doing a R5 motor send the crank out have it restroked 4.185 bore A P7 heads will out flow a max wedge head any day of the wk Larry Smith just did a set for me before he past away and they go over 425cfm with a 2.20 valve theses motors can still be brought right if you look around im sending a crank out now to restoked to 3.50 with a 4.220 bore gets it to almost 395 cu to have the crank restoked is 1000-1200 bucks Id talk to Eddie Middleton he just built a motor for a guy that races in the silver something its called and he whent 242 mph in a old cup car
