Help ID a Ford Camshaft

[73azbronco]

Hi, I am 20 months into my 8 month 5.0 build.

I bought a cam from a guy over on the ford F150 website, he says it came out of an new explorer crate motor from 1998 which he installed an E303 cam, he says it's an F4TZ-B hydraulic roller camshaft out of a new 1998 explorer GT-40 "P" long block.

I get the cam and it looks great, but has no ID markings, only date time stamp of manufacture 11/17/98 11:30.

There is a "TE" and "TE E" with lots of"xxxxxx" stamped on the shaft by the cam gear, but thats it except for what might be three ones "111" by the back end of the cam. Those marks may be machining marks...

I have asked the guy to try and get the crate motor part number, but if he can't, is my only choice to go to a machinist and have him dial this in to see what it is?

Oh, and anyone running a B cam?

thanks

Well the date code alone will back that it is a stock Explorer cam. What do you want to know about it?

I was hoping for a part number to verify specs. Seller seemed to think it was B Cam, but does that mean a B cam or a B303 cam? Thats my question.

B303 cams have .300" lift at the lobes. Measure it. If it measures closer to .270" it's an explorer cam.

TE usually stands for Truck engine. I'm not sure if the late model codes are the same as the early model codes I cant imagine they would change it. I would think that the explorer would fall in the truck line.

I have a stock explorer cam in storage with a similar part number. The 'B' does not mean it's a 'B' cam, It would seem from what you supplied it's an explorer cam...

I measured the lobe, closer to .27 than .3. So, now whats the specs on a 98 explorer cam, anybody? Part number?

I searched and found these numbers, just slightly smaller than the mustang cam.

.422/.448 valve lift and 256/266 advertised duration
