in your book you write about a cam being too small or too big. What is the max displacement for a stock cam before it gets too small ? I can`t see a EAC cam feeding a 304ci Flathead even at lower rpms... Michael |

Re: How's your cam ??
When I wrote about a cam being too big or not big enough it was a reference to the desired RPM level at which the cam design operated most efficiently. Although there is some truth that a larger engine can run with a longer duration cam, it is basically true only because the added displacement helps overcome the poor performance at RPM below where the cam duration is suited for. It is not really a matter of properly "feeding" a given size engine, but rather, a matter of having a cam designed for top efficiency in the RPM range desired.

Re: How's your cam ??
Hello I have the 53 Mercury cam. I found a article on the net. Can not remember where. That said that Ford spent a lot of money and time to develop the late model mercury cam. In this article the author said that this can was probably the best all around cam. Does anny one remember or concur with this statement. I can't remember what years I think the 51,52,53 were included.

I can't believe these small changer can have any noticeable affect on drivability.

Tom - where did you get your specs for your camshaft? I bought a 3/4 MCF cam from Mark back in 1994. At that time, the MCF cams specs were as follows: (According to the June 1994 issue of Street Rodder Magazine, pg 135) Grind Type Intake Exhaust Lift Duration 3/4 29-72 72-29 .370 282 Degrees 7/8 29-72 72-29 .390 282 Degrees Full Race 28-73 73-28 .420 282 Degrees The reason I ask is that I ran this cam from 1994-1996 and for some reason I cannot remember why I switched it out for a 260F Schenieder cam. I was measuring the lobes and there is a .015 difference between the exhaust and intake lobes. Mine is marked as being a 3/4 MCF. I dont have a dial indicator to mearure the life but I measured the lobe itself and subtracted the heel on the opposite side. I came up with .391 exhaust lift and .376 intake lift. Seems like a have an 13/16 cam?? Anyone have an idea? |

Chuck Steevins
I'm not sure which Ron your referring to but I think the 77B is the modt useless cam on the market today. It's basically a stock cam for $200. Fore that kind of money you can get several better cams depending on application. |
