I am skeptic now that it had the Fisher head, maybe another 12 port, but this cam has been run with the stock 819 that is on it now. It is a billet cam and I have seen reference(in the last hours since finding the F6) several times, mainly in the California BIll book, about using the F6 with the Fisher head on more than one occasion...of course teh F6 is more than likely a somewhat genereic grind they used on all manufacturers. I have seen articles with a Howard F6 in a flathead Ford and 50s Olds V8 as well. I haven't found any specs on the cam, but all motors referenced with this cam where more of the full race variety .
I looked up teh Howard website and they have no Emial to make an 'easy ' inquiry. I might try to call after teh kids are in bed.
It's kinda fun tearing an old hotrod motor apart that you have never seen the inside of before...it's abit scary as well, this is the first time i have ever bought a used complete motor that has supposedly been hopped up in the good old days....at least i didn't tear it down and find a bunch of stock wore out crap...bore looks in excellent shape, one minor vertical scratch in cyl 1, but i can live with it for a street motor. the motor is still on the running stand, I might try to get it up onto a motor stand so i can flip it over and better inspect the bottom end. I'm curious about the pistons. If they are Jahns, they shoulve have thier name on the inside of the skirt. Oil pump looks new, but still has the swinging pickup, I didn't realize these had those....I assume you can get ARP bolts for teh stock rods or modify some others???
