I'm looking to install a new camshaft in my 61 ranchero. Currently it has a comp cams 260h. (Don't remember exact specs). Reason for wanting to install a new cam is I recently acquired an aussie head and 3 sidedraft weber intake. The carbs will be replaced with efi throttle bodies from borla, 2900 series. The new head setup will allow for much more air flow than my current e8, 32/36 adapter setup. With the new head, I also acquired some yellow Terra 1.65 rockers, which reguire new lifters.
I would like to match the new cam to the head to make most use of it. I know the head will support much more cfm, and therefore more rpm. What is a safe limit for these engines? Engine is rebuilt with ARP hardware at all 3 critical points.(head and main studs, rod bolts). Using a stock 68 block .020 over, with stock 68 rods(with arp), t5, a/c, 3.73 rear, header.
Thanks to super4ord for the head.
