Re: Winfield SU 1R N
I have been rummaging thru the net and from what I have found, the R stands for retarded time. There was a A an d R cam. Hopefully ,someone will chime in here with some actual info.

Re: Winfield SU 1R N

Re: Winfield SU 1R N
The info that I have comes from an old Roger Huntington publication (How to hop up Ford and Mercury V-8 engines).
Intake opens 22 BTDC Closes 66 ABDC, by my calculation that is 268 duration. Overlap 40 degrees. Exhaust opens 62 BBDC Closes 18 ATDC, by my calculation 260 duration. Overlap 40 degrees. Intake lift: .315 Exhaust lift: .305 If you would like to know more contact Elgin Cams, 707-545-6223 and ask for Dema. He professes to have been a protege of Ed Winfield and should have more data.

Either Dema or cam grinder Pete will be able to give you the straight scoop on these cams. |

Re: Winfield SU 1R N
Thanks to all. The cam I have is not a regrind and appears to work with a std adjustable lifter. The regrinds must use the adj. tappets with a thick head.

Re: Winfield SU 1R N
I've got two regrinds that are marked 1R. They measure .350-.355 on all of the several lobes I've measured. This is probably no help, as they were reground locally, by someone that posted on his forum. ie... origin unknown / questionable.
