Has anyone installed the cam John Mummert sells called the Y-265-S? (ground by Clay Smith). My 312 many years ago had the C4TZ-6250-A cam installed and I wanted to replace it with an equal or better cam than the D code 312 had from Ford. Suggestions please.

Isky RPM 300...228* @ .050"...I wouldn't put a Clay Smith cam in anything! JMO

Lord gaga, why not a clay smith?
Did you have a bad experience? I for one would like your opinion and feed back. I have a CS 292-S in my build now. It's not yet ready to run and would like to know any potential problems with the cam itself. Thanks, Rowen

Hi, I like a Isky E4 for a stock engine, the cams that John sells are good, George at Clay Smith does a good job.

As far as I'm aware, I've not heard anyone else on this site saying anything bad about a Clay Smith company cam. John Mummert has a good reputation with the parts he sells, and I'm sure if there was a problem with their product, he wouldn't be selling them.. Anyway, unless I'm mistaken, the C4TZ-6250-A cam is a non original replacement cam, likely introduced in 1958, which is definately milder than the original EDB 1957 cam. The correct '57 cam is not handled by most cam companies. It is however available from Oregon Cams in Vancouver Washington. I believe the price is about $149.. However, if you want something beyond that, the 265-S cam is somewhat hotter than the 57 cam (which Mummert does not stock), but is recommended by him for use with exhaust manifolds & if with a Fordomatic. It has a wider LSA so likely is a bit better on idle than the next cam up..

I've used 3 of John's cams, all a bit hotter than the 265. Last winter I put in a new custom grind. It's was a Clay Smith, came with the Cam DR sheet. Degree'd in fine, broke in fine. I'd use it again in a minute.

Rowen, The problem I had was with a C.S. cam for a small Ford 6 cylinder engine. The timing specs on the cam card didn't match the cam when degeeing it. Tech support was not much help. Judging form other members responses it seems it may have been just a fluke in my situation and their Y Block cams are OK. I probably should have kept my opinion to myself!
I've always had good results with Isky cams over the years. I have the RPM 300 in my .040 over 312 installed 4* advanced. It has a very slight lope with 16/17 inches of vacuum at 800 rpm idle and pulls well from 1500 to 6000 rpm. My car weighs 3650 lbs. and has a standard 3 spd. with overdrive. It has a Holley 600 cfm on a modified B manifold, otherwise stock. It runs very well. I'll stick with the "Camfather".

In LG's defense, there was something on the cam tag that confused me, too. Fortunately, I had a very experienced pro engine builder who set me staight. I'd forgotten about that. I also liked the Isky RPM 300 I had years ago.
