Got given a motor that has been sitting behind a guys shed for a number of years. Just want to know what size motor it may be. He reckons 1600 these are the numbers AD72452...turns over and no end play.

AD is 1600 i got same prefix on my 2017 i am building. Pull it apart and build yourself a stroker motor.

Yep AD series is about 72, 1600tp

Nice,my youg fella and myself are pulling it down and see what the bottom end looks like

Hopefully bottom end won't be bad and i can give it a bit of a tweak. no stroker this time round but need something i can bolt my dells to.
