Default For Sale: M28-21 310 HP 16v Motor

I just salvaged a M28/21 16v motor in Philadelphia this last weekend.

This is the 310HP, 10.4:1 CR motor with the twin distributors as shown below.

I'm told this motor last ran 4 years ago and ran well. The car was parked in Pittsburgh and vandalized. Then, after insurance delays, more vandalism, more delays, etc - the car just sat.

The engine does turn over by hand and has no rough spots. The motor is complete. I do recommend it be gone through before it is put in service, but that's up to whoever buys it.

I can ship it motor freight or you can pick it up here.

I am asking $3800.

Hi Carl, this engine has the 10:1 pistons. Up to engine 596, see PET. I have one at home myself I opened up. Sorry.

Good to know, no problem. I was using the info from the little Tech Specs books.

This is the reason why the 10.4:1 will probably have even more HP. It was certified using the "old" pistons from the M28/11 or M28/12 with 10:1 and came to 310ps. Knowing how the factory worked in those days, they probably still had a lot in stock. The extra 0.4 should make same HP.
