Re: Stock versus Performance Cams
Well after working on my trans, converting a postwar light truck open drive trans to a closed drive system with most of the LZ stuff I went back to the cam question.
I'm leaning towards Ol'Ron's advice but them I found a little more out... I have two cams actually, one marked 8CM and the other EAC-A. Are either of these cams a good cam for my plans or should I get the Max1 style regrind? No sense spending money if there won't be a noticeable improvement. |

"Noticeable improvement" and "no sense spending money"? If either of those cams check out good, use it.

Re: Stock versus Performance Cams
I'm not sure I get your meaning. Are you saying that both of those cams are very close to the Max1 so I should use them? Or are you being a little facetious?

Re: Stock versus Performance Cams
What are you aiming for ?
You want to cruise mostly with good mileage...go merc cam and single carb ! That 32 will move as fast as you need...and then some.. You want lumpy idle...or have a real heavy rightfoot frequantly used...then maybe a more agressive cam. I think overcamming and overcarbing engines is the most common fault made... |

Re: Stock versus Performance Cams
I am serious. In my opinion, the "seat of the pants" increase in performance isn't worth the extra expense. The specifications of the 1CM are closer to a MAX-1 than a regular 8BA cam.

Re: Stock versus Performance Cams
Go with the 8CM.

Thank you and I hope you weren't offended by my comment. It seems that the 8CM is the one then. I bought the C8BA engine which never has had any machine work but the interesting part is that it came with a Merc crank, Pistons, and cam. Maybe the factory ran out of C8CM blocks that day... Any imput on the EAC cam? I'd like to know just so I know for future reference. Thanks! Last edited by Fortunateson; 04-16-2020 at 01:56 PM. |

Re: Stock versus Performance Cams
I have no technical knowledge on the EAC cam, but would expect it to be as good or probably better than the earlier Mercury cam. That extra 15 HP in '52 and '53 didn't all come from an increase in compression.
Anybody have the specs? |

Re: Stock versus Performance Cams
The EAC cam is essentially the same as the 8CM.

Re: Stock versus Performance Cams
Original style or type. I would not even think of using used springs once everything is taking apart for a rebuild. Think of the absolute pain in the neck it would be to replace one if it broke. Stock -style springs are under $100. Cheap insurance in my book.
