"Now, I'll shut up. I've probably posted just enough stuff on this to look like an idiot... :]" just blame it on the pain drugs mark. id buy that one. ;-P i get the idea of how it all works, but as far as knowing how to select a cam based on lift vs duration vs degreeing, psh, thats the only part on a motor im a little grey on.... i have that desktop dyno 2000 program. not very many engines to select from, but i was able to use it to get a cam that was REAL close to exactly what i wanted for my 77 f250, and get a good idea of what it should do in my 76 ranchero frod 400 drag car. i need to learn to degree a cam. 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. dave stohler my rambler pics@ http://picasaweb.google.com/das24rules _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
