Yesterday I picked up a 301 Chevy from a fellow hamb member. We got it torn down today and I’m trying to figure out what the cam is. I tried doing a search and haven’t come up with any thing. Does anyone have any info on these numbers? to me it looks like an Erson cam?? Sent from my iPhone using The H.A.M.B. mobile app
Erson phone number:1-800-641-7920. Or online: pbm-erson.com/ContactUs. I've got an old, but NOS Erson cam that I had to contact them to find out the specs. Turned out it was a really MILD hydraulic grind, but it'll probably be a good cam for my 265 build. I am Butch/56sedandelivery.
Thanks for the phone number Butch. I’ll try and give them a call this afternoon. Scott Sent from my iPhone using The H.A.M.B. mobile app
Ya never know, back in the day i had a 283 & no one could adjust the valves corectly. An older Mopar racer got the # off of it and sent it to a Chevy guy. Turned out that the cam was one of 3 special Duntov cams that "got lost" at G M. It had been used in a sprint car in Fremont Ohio before in ended up in my 58 Vette. ??? Go figure.
I think you are thinking of the early 265’s like 55. I think even 56 is not groved. I could be wrong though. Sent from my iPhone using The H.A.M.B. mobile app
I ordered a cam thru Friendly Chevrolet that Smokey gave me the # when I went back a couple of months later to order another one they told me that was not a good part number, go figure it out.
That looks like a winner! And would makes sense with the cast Jahns pistons. Anything too radical and those pistons might have come apart. I think it is going to be a fun little engine to rebuild. Scott Sent from my iPhone using The H.A.M.B. mobile app
Jahn's cast pistons were sure popular "back in the day". I have a STD bore set for a 265 Chevrolet, flat-tops with two valve reliefs, and they are polished (first set of those I've seen). They are NOS, but not in the original box; that box basically disintegrated with time. They'd be perfect for a Junior Stocker type build. Only 55-56, 265's utilized the rear cam journal notch, that provided pulse oiling; 57's came with the improved, full flow oiling with both the 265 and 283 engines. I think as long as you use "as good of gas" as you can find, have your quench set up correctly, and don't lean to hard on advancing the timing, those pistons should be fine; detonation is the enemy there. Too bad that "301" did't have one of the Hi Flow cams in it. What heads, if any are on it? I am Butch/56sedandelivery.
Butch, No heads, just a short block but I have a set of camel backs that will probably end up on it. It will be a poor man’s build a d give me time to finish my “nice” engine for the 55 g***er. Scott Sent from my iPhone using The H.A.M.B. mobile app
