Winfield Cam Question
 

I purchased what a gentlemen told me was a Winfield SU1A camshaft, but after closer inspection, it's definitely not. It looks to me to be a regrind that was probably preformed by Winfield just not at the SU1A specs. I have attached the camshaft spec card and would like to know some thoughts on type of performance I could expect. I'm going with the typical build - 59AB, 2x2 Carbs, 40 Over, heads etc.
Thanks

Post a picture of the end of the camshaft. Is it stamped Winfield?

I's not stamped with the Winfield logo. 5T F235 is on the end and that's why I believe it's just a regrind, which is totally OK. I'm really more interested in the overall performance characteristics.

From the shape of the lobe and the tag numbers, it is a very mild street grind, somewhat like a 3/4 Winfield. Not much more than stock.
The genuine SU1A was a good all around hot rod street cam in it's day.
It did all things equally poorly. Here are the specs from an original ground by Ed himself.

Winfield SU1A (1953)
360 lift 280 duration on the intake 28-72
360 lift 286 duration on the ex. 74-32
111 degree lobe separation

Pete - Thanks for the information.

You have a small engine, thus low compression. For atreet use torque is better than HP, here you do;t have either. .360 lift max with 220 duration, this keeps the torque in the right place. Get g=the small 65 ccl heads for more CR.. Carbs don't do much on this size engine, get JWL;s book, save you alot of money and abetter engine./
