With all the Windfield cam copies out there, does anyone have an original Winfield cam so you can measure the height of the letters stamped on it? I am mainly looking for the height of the stamped "WINFIELD". The height of the other letters such as if it had "NN", "SU1A", "R1", etc. would be helpful too as I think these may have been slightly larger than the "WINFIELD". Thanks, Roger
First thing you can check is to see if it is somewhat smooth between the lobes . Winfield took the rough casting out of the cam between the lobes. Alot of the knock offs don't take the time to finish the cam off.
Do you still need this information? I have an original Winfield SU1A cam I could measure for you. Do you need any pics?
I took some pictures of my cam and now noticed it is stamped WINDFIEL with a hint of another D. I thought Winfield was the correct spelling. Any thoughts? I have no reason to think it is not authentic. Thanks in advance for information. Wadester
From memory, I think my Winfield had a perfectly aligned "Winfield", letters obviously held together in a fixture and not stamped one-by-one like that.
Wadester, Your cam is definitely a copy and it is spelled wrong. Bruce is right about the "WINFIELD" stamp. It was either a set of stamps held in by a holder or it was a custom made single stamp that Ed Winfield used. Only the grind number was hand stamped and was uneven because Ed Winfield mixed and match the Intake & Exhaust lobes all the time. Several years ago, I had some discussions with Harvey Crane about Ed Winfield and his cams. Harvey told me that there was a significant difference in the font size of the "WINFIELD" and the "SU1A" stampings. The "WINFIELD" stamp is a smaller font than the "SU1A". Harvey personally knew Ed Winfield back in the late 60's and 70's. Harvey also owns several original Winfield cams. He was able to verify some pictures I had of a 3/4 Winfield as to being genuine, but I have never seen a genuine SU1A or any the other grinds that Ed did. Roger
Yes, the "Winfield" part was crisp and perfect, the sort of stamping you would expect on a good gun. The guy was obviously proud of his name!
I have a Winfield SU camshaft for flathead V8. Wondering if anyone has specs on this cam. want to run it in my 276 flattie.By the way , the stamping in this post doesnt look any thing like mine. Letters are perfectly aligned w/capitals and SU is even bigger than caps. thanks rob
I have an original Wimfield cam in my flatmotor, hand polished by the guy who bought all Ed's equipt. and rookied under old Ed. The mans name is Dimetre Elgin ( Elgin cams up in Santa Rosa ) He is a great guy and can tell ya anything about Winfield cams; give him a call. That stamping on that endshaft is fake.
I'm bringing this old thread back since I figured out I have one of these Winfield "copies" in my motor. Whats the deal with these, do I need to replace it now? I hate to buy a new cam at this point but if this ones junk I'd rather do it now then after the motor is back in the car.
There is nothing wrong with a copy, espeically if it was an accurate copy. It is just where sometime in the past that another cam grinding company took an original Winfield or even someone else's copy and put it on their cam grinder and set it up to make a set of master cams so that they could later grind the Windfield profile onto other cam blanks. The only things that can make the copies not so good if there cam they copied was worn, the cam grinder did not pay attention to and make an accurate copy, or they did not check the cam they were make a copy from to make sure it was not bent. Flathead V-8 cams are notorious for being bent since the base circle is small at about one inch in diameter and only have three cam bearings. Ed Winfield was a stickler for precision. Ed's cams where ground with no more that 0.0005" runout (1/2 thousandths) on all the lobes. In general, you would still get the overall basic cam lobe shape from any copy and on a street motor, you would probably never even be able to detect any noticable difference in power between a not so good copy, a good copy, or even and original. In a nut shell, don't worry about, just run what you have. Roger
Along about late 1953 / early 1954, I bought a SU1R from Mr Winfield. I seem to recall there were 3 of the 'SU1' grinds. The SU1, SU1R and the SU1A. The 'R' was 4* retarded for heavier cars, the 'A' was 4* advanced for lighter cars. As I had a 1949 Mercury 4 door sedan, I went for the 'R' cam. Worked well for my needs. Long time ago!
Bring this back to the top help please This weekend i bought a 8CM engine and when i broke it down i found that it had a winfield cam in it that read "winfield in small font:", then had NN just below his name and the number 1 in large font, then just down from the 1 it has 3/4. Would appreciate any input. Thanks
