Tryin To Figure Out What Motor I Have

83GTMUSTANG · 10-31-2005, 04:34 AM

The Motor Is Out Of A 78 Cougar Its Iether A 351m Or 400 The Block Codes Are D7te A2b And The Head Codes Say Deae A2a So Which One Is It Or How Can I Tell ...............

82 GT · 10-31-2005, 07:11 PM

Ford never put any of the modified engines in a cougar. It's either a 302 or 351w. That engine code indicates that it's a 1977 engine.
The head code you gave, you probably misread because the second digit should be a number not a letter.

83GTMUSTANG · 10-31-2005, 07:32 PM

yeah its d5ae a2a and THEY DID PUT THESE IN THE 78 COUGAR ALSO OFFERD 302, 351W, 351C, AND 351M, 400 IN THEM...... IM NO ITS NOT A 351W, 302, OR 351C IT HAS THE BIG BLOCK TRANS BOLT PATTERN ON IT I JUST WANNA NO HOW CAN I TELL WHICH IT IS 400 OR 351M THEY BOTH HAVE THE SAME HEADS, INTAKE, CAM, DISTRIBUTOR,WATER PUMP,AND RODS JUST DIFFERENT PISTONS AND CRANK............

82 GT · 10-31-2005, 07:44 PM

Please show me facts that they put the 351m or 400m in a 1978 cougar. I could be wrong but I don't think so.
"D5" indicates 1975 heads

I stand corrected. Anyhow, IMHO, I would opt to look for a Windsor engine because there are more aftermarket parts available.
You'll spend less money to make more power with a windsor than you would a "modified" engine. That's just me though.

The only way I know to tell them apart is if you take the engine apart. The 400m has a longer stroke(4 inches) and the 351m has a 3.50 stroke. The pistons in the 400 also have a higher compression height.
Unless somebody on here can decipher the rest of the codes.......

~The Jester~ · 11-02-2005, 03:26 PM

Need more than casting codes to tell.

If it's got a "big block" (BTW, Ford never built a "big block" that was Shivvy) bellhousing pattern, it's definitely a 351M/400/351 Cleveland. Since they didn't put Cleveland's in a 78 cougar, and 62% had a 351M and only 5% had a 400, I'd bet money it was a 351M.

To know FOR SURE, tear it apart and measure the crank throw. That's the only way to tell for sure.

grey88gt · 11-06-2005, 08:00 PM

I agree with Jester , a 351m will have 4.00 bore and a 3.50 stroke where as a 400 will have 4.00 bore and 4.00 stroke. If Ford didnt build a big block, what is a 460 classified as? I know alot a ppl called the M blocks as big block because of the bell housing bolt pattern, but there not.

Did I hear an echo in here.

Check if the timing cover is part of the block. If it is it's a modified engine if not it's winsor block.
