8cm cam grind I have an 8cm camshaft that does not look too bad but when I chucked it in the lathe and measured the lift I found values between 0.330 and 0.320. One was at 0.335. These numbers were repeatable. My question is can this cam be the ground to something acceptable close to stock? I know the base circle changes but I think this will not be much of an issue.

Re: 8cm cam grind Frank:
I believe Tilden Technologies does have a "hot" stock grind. It may be the EAB cam profile or something like that. Check out their webpage or give them a call. https://www.tildentechnologies.com/ Good luck. |
Re: 8cm cam grind Also, 'Pete' Samuelson (here is on here as 'Pete') can grind all sorts of great profiles - I imagine he has something that would work for you. I'd drop him a PM or eMail and see what he says . . .

Re: 8cm cam grind Pete has my cam right now,,,,,he has a good reputation.

Re: 8cm cam grind I can put a stock Mercury grind on you cam core. I am in New Zealand for a few weeks so would have to be when I return.

Re: 8cm cam grind Thanks for all the replies. Weighing options. I guess the most important thing is that even though a cam looks ok you really need to measure it.

Also suspect that grinding it in an attempt to make it perfect will not produce any noticeable difference in performance. |

Re: 8cm cam grind I'm using a stock EAB cam in the 280, and am real pleased with it;s performance. Torque is amazing

Re: 8cm cam grind Pete or Tony:
I have an EAB cam that has a damaged lobe. I'll try to get pict, but it has a chip in one of the lobes. Can something like this be successfully repair? |
Re: 8cm cam grind I have a Mercury engine in my '51 Ford. I had an Isky MAX-1 to install in it, but after checking the specs on the "Tilden" page and some discussion here, I left the stock cam and saved the Isky for a later build. In retrospect, I think I did the right thing.

Re: 8cm cam grind The EAB cam was the last one FoMoCo made for the flathead V8 engines. It was designed to replace the 8BA cam to give the cars more torque for those that still had 239 CID. The 8CM cam was desiged for the Mercury 255 to give it a bit more torque. The Mercury cars were heavier than Ford beginning in 1949 but by 1952, the cars were a lot more similar in weight so the 239 needed a boost. The EAB cam was the replacement cam for all of them and Ford had them available for a long time after flathead production stopped. I still find NOS ones now and then.

Re: 8cm cam grind I wonder what the specs. are on an EAB cam?
|
Re: 8cm cam grind They are very similar to the 8CM specs. .330 lift. 205 deg. duration at .050 lift.
|
Re: 8cm cam grind Just out of curiosity, does anyone know if there are "1CM" ('51 Mercury) or "EAC" ('52-'53 Mercury) separate grinds?
|
Re: 8cm cam grind I do have a 1CM cam. Haven't plotted it though.
