EDB 6250 D is the engineering number for part # B7A 6250 C
It is the 1957 Blower camshaft
Let us know what markings are on the bumpstick.

If your considering selling it, I would be interested

I will take a look at the cam for any markings. The tube label is marked EDB-6250-D under "special racing camshaft"

Unfortunately the tube I.D. isn't readable. As Oldmics asked, what are the markings on the cam? If it's a genuine  EDB 6250-D cam, it's an original 1957 std cam. That cam is not usually available from most suppliers, as it was superceeded years ago by milder grinds from the past or finally the 1964 Cab X grind which is a truck grind. (some of this data is from J. Mummert's article in Y-Block Mag., issue # 77-2006) This happened when the Y-Block was religated to being a base engine in 1958 by the intro of the F.E. series engines That cam has more duration & lift than all the other std cams Ford issued, other than the supercharger grinds & possibly (?) the Isky E-2 which was reportedly used in the 57- 285 H.P. 2-4 Bbl engines... The only company that I know of,  that claims to have that profile in stock, is Oregon Cams in Vancouver WA.  If I recall, they sell the bare cam as of 2015 for $150.00 on a new core.

Are there any markings on the camshaft itself?

Hi,
I have a NOS in the tube EDB-6250-D Camshaft. Does anyone have any more info on this cam? I've attached a pic of the label on the tube.
Thanks

Hi Ted,

  I looked at the article that mentioned both the T-85 and the T-89......Correct me if I'm wrong....The T-85 could be found with an R10 tail stock? I thought the R10 was only found on the T-86 trans? And there are significant differances between the T-85 and T-89.....Not just the side covers..Hah that's funny...I know exactly what your saying when you mentioned the flat shifter levers verses the offset ones.....I have two T-89B transmissions.....One I put in the car and the other is a spare....I'd like to take a T-85 apart and look at all the differances between that and the T-89......At what time period did the T-89 come out? the guy I bouht the trans from said it came out of a 57 Ranchero.....Is this possible?

Thanks for the help....nice chatting,

Jeff

Hi Frank,

  Thanks for the advice......I feel as though what I have is good......I don't have any complaints.....I can't say that I'm puting myself in any kind of competition....A guy I know down in South Caroilna who has worked on supercharged car and thunderbirds mentioned it to me. He mentioned using a 3.70 diff. That's the only reason I asked about it.... I, do have an issue with the speedometer reading 10 mph higher then it should be.....I should have a 21 tooth speedo gear......the biggest gear I can get is a 19tooth....Let me explain.....I was formerly using a T-86 top loader trans....When I put the T-89 in it required me to use hollow type speedo gear with the clip.....( the speedo drive gear is the opposite hand of what I had with the T-86 trans. which requires another type of speedometer gear the red 19 tooth gear  Is there a larger tooth speedo gear available for this T-89 trans.? where would I find one? a 21 tooth gear should do the trick....

Thanks for explaining what Ted was saying.....I'm going to see if I can look up the website he mentioned.....

Jeff, What Ted said. The T89 is a later, supposedly stronger version. the R11 is a stringer version of thew OD unit. Nothing in it except the speedo drive gear intercahnges with an R10.

    Only you can tell if there's enough gear, if it pulls well in OD with the 3.89's, keep them.

Jeff.  The T89 gear box and the R11 overdrive unit are typically found together and are the pinnacle of three speed overdrive development for those series of transmissions.  The T89 has the offset shifter pivots versus the T85 having the shifter pivots level with each other.  The R11 is the newer version overdrive versus that of the R10.
