318 with 675/318 or 974/360 heads Cam Recommendations

Get a 318 roller motor they have pistons .040 in the hole, send the cam to Oregon cams grind 1006 260/264 duration 480 lift port out the 302 heads and you got a fire cracker on the cheap! Also you can mill some 360 heads and stick them on the roller block compression would be decent. You can find them in the junk yards get a low mile fuel injected one less wear on cylinder walls. I took apart a 250000 roller motor and there let me tell you the thing had wayyyyy Less wear than my 72 318 with 200000k
