I searched everywhere that I could think of including the old team members.

Unfortunatly,the majority are at the Christmas tree lites in the sky.

The few that I had communication with had vague recollections of those days.

I even contacted Buddy Barr casting to no availe.

I"m open to suggestions.

Probably true in some cases John, but in 56 when the Fords started winning late in the year, Keikhaefer would file protests on the engines, so using an unauthorized cam could get you disqualified.

I suspect that back in the day, different race teams experimented with various aftermarket cams, and when they found one they liked, they told Ford, and Ford said, "yep, that's the correct cam, here's a part number for it".  At one point Holman-Moody began grinding their own cams, not sure about Bill Stroppe.  Smaller independent teams probably experimented with aftermarket cams also.  Anything to keep the scrubs at bay.

Oldmics: the name escapes me at the moment, but you probably know it. Who ran the Merc racing teams around 56-57? If you could connect with somebody who was with them at the time, maybe you could get some definite info?. Also, John Mummert has I believe, speculated that some of Fords 260 or 285 h.p. cams may have come from Clay Smith's shop. But I'm not positive on that info..

I know this is obvious, but there is some FANTASTICALLY good knowledge on this forum...



Thanks everyone!

To make things a bit more confusing,the M260 cam had two variations.The more common one may have been the Isky E2.

The blower cam was definatly not used in the M260 setup. The blower cam was ground on a different centerline than the M260 camshaft.

The way the specs were measured by both Ford and Isky were different from each other, so a clear answer is not easy math to do.

I should have a definitive answer shortly from Ron Isky as to weather or not the M260 cam was an Isky E2.

All of the information that I have points to it being the first version grind on the Isky E2.

FYI-I am also having the original blower cams remade along with the M260 cam.

Oldmics: Yes, you are correct, it refers to the M260 kit but does not give the cam spec. My mistake. There are 3 cams for Merc's referred to. One is an upgraded 235 H.P. 1956 one, part number EDB-6250-B. I'm curious as to whether some Ford & Merc 260 h.p engines used the supercharger spec cam or the sometimes referred to Isky E2. It seems like no one knows for sure, not even Bruce Young at YBM.

Problem is, I buy any old car, I'll be living in it.



My wife simply doesn't share my passion for old vehicles.



Now my daughter, on the other hand...

Those listed specs in Eickmans book you refer to are not for the M260.

I also originally thought they were the M260 specs until I researched a bit deeper.

Next weekend, April 3,4,5 I'm going to Toronto where RM is having an auction. There is a sweet 56 Merc in it.  Want me to buy it for you? src="http://www.y-blocksforever.com/forums/Skins/Classic/Images/EmotIcons/Tongue.gif" width=20 border=0>
