>i have heard that the frod cams were retarded by as much as 6-8* for the late 70's. i need to know >what to do about mine in the chero. It wasn't the cams,, it was the timing chain gear. And mostly on the 460s if I remember correctly. Make sure and use a HP timing chain set and you should be OK. Wouldn't hurt to check the cam though. If in ANY doubt about cam choice,,, CALL THE MFGR (except Comp!!,, don't EVEN get me started). I have found MOST of them (especially the smaller guys) to be very helpful in picking the correct cam for your combination. Dyno 2000 is getting pretty old (I was a beta tester for it). You might want to look at this stuff,, http://www.virtualengine2000.com/ They have a free engine kackulator that is helpful. But HEY,,, that's just ME!
