ICL on aftermarket 460 camshafts
I'm interested in peoples experience with cam timing on the 460. I bought a Summit 3501 camshaft and fitted it into my first, 1971, 460 engine in my 1969 Cougar. Ran terribly at straight up 0 degrees with a Cloyes 9 key timing set. Took timing cover off, removed timing set and checked position by fitting old, stock, timing set (early straight up) and it went straight on without turning crank/cam. Fitted the Cloyes 9 key at position A8 by turning the crank slightly and upon completion the car was tested and it went very well.
I then read an article on the FordMuscle website concerning a 460 with a Comp Xe274 cam running poorly. Again, straight up conspired to be 113 degrees ICL and it was advanced by 8 degrees via the timing set to get to 105 degrees (target was 106). Ran much better.
I am currently running my 264/268 @0.050 cam at 4 degrees advanced and feel it could happily go the extra 4 degrees advanced.
I have a DTI gauge at hand and am going to play around on my spare short engine with a degree wheel fitted to check my next camshaft.
Why do cam manufacturers advertise about cam advance being "ground in" when you need to advance them? Are other engines the same?
