I just want to know what you can tell me from the numbers on it. C90E-6015 B 8 is on the pass side rear of the block with 9L3 in smaller letters right below it. in between the lifters, under the intake, it had 351 WF 8 The only markings I could find on the heads were 8H23 (found between two pushrods.) and the number 11 near the rear of the pass head on the outside. If I need to look somewhere else, just tell me and I'll update this post. If possible, I plan on stroking it and putting it in my 67 F100. I have about $2500 to spend on this. Thanks for the help.

They should be on the head gasket surface (underside). I believe the C8TE-6015-A casting number is incorrect for the 351W. That number would indicate a part designed for a 1968 model year truck, when in fact the 351W was designed for the 1969 model year cars. Your casting number of C90E-6015 B is correct for 1969-up, and the 9L3 is a date code indicating November 3rd, 1969. A date this late in the year means the engine would have been installed in a 1970 model vehicle. 351 WF 8 indicates engine size and Windsor Foundry. 8 may be a pattern (mold) number.

Double check that first digit to make sure it's not a 9, which would agree more with the block date code. How original does this engine seem to be? Is it a 2V or 4V engine? Are the piston tops dished or flat (with valve reliefs in either case)?

The heads are the same between 2V and 4V engines. Pistons are dished in the 2V vs. flat top in 4V. Reply 0 0

I thought they raised the deck height and left the rotating assembly alone to reduce the compression, which is why the HP numbers tumbled ridiculously in the early 70s (1972??). I'm far from an expert, just asking.

I got the dimensions reversed. Thanks for spotting that so the post can be corrected.

Gone thru 2 already. I have the C90E-6015-B Mustang block for sure. Its in a 77 manual. Took old starter in and matched up, which was grinding then went out probably not being the right one in the first place by previous owner. Just bought truck day before. New starter wouldn't fit due to bolt holes didn't line up. Next starter nose is too big. Measured everything for round 3 today.

If your engine has the bell housing for a Mustang, which weren't available in 1977 with 351, but still used the same starters, the generic model number is 3132. It has a shorter nose than the motor for the automatic transmission, model 3124. There are two potential flywheels; 10" with 157 teeth, or 11" with 164 teeth. If the bell housing doesn't match the flywheel, even the correct motor is not going to work.

As has been said, there's long and short snouts, the wrong one might be what's causing your problem, or it could also be that the C-clip that limits the "Bendix" drive travel has failed or is missing.

I don't know what the Ford or Motorcraft part numbers will be. If you look for "starter motor for 1965-1977 v8 Mustang" you will find two generic numbers, 3124 (automatic) and 3132 (manual). The numbers are used by all the aftermarket sources.
