best of both worlds ; torque on a budget (diet )

Make your Cougar run faster, handle better, and jump higher... okay maybe not jump higher. If you feel the need for speed, this is the place.

A 427 Ford weighs about 100 pounds less than a 428 CJ due to its aluminum intake. Those weights are off, someone is on drugs if they believe a 429 - 460 is 10 pounds lighter than an FE. Go pick up a 460 crankshaft and compare it to an FE crankshaft. Ditto the heads or block.

The 351M / 400M is an odd duck engine, with its bellhousing pattern matching a 460. Not much in the way of performance parts available, you would likely have to build custom headers yourself to put one in a Cougar.

Two engine builders I have worked with since "back in the day" would not bore a 'M' block.

Mystified why you'd want to pull the FE in a rare/unique cat and replace it with any other combo. Even if you found something that you thought would work a little better: who cares?
