..... use the 460, there is no substitute for cubic inches. Plus will the 352 run on todays pump gas??? I don't know the compression but it might not. Plus the 460 is rated at gross H.P. while the 352 is net H.P. If you convert the 460's net to gross it'll probably have more HP & for sure more TQ. Someone mentioned that you could wake up the 352 with a little work? If you want to REALLY want to wake something up put a little work into the 460!!! Thats a BIG motor. It probably just needs better heads/cam..... just my opinion, Bill.....
