I'm looking for a spare rebuildable gen iv 454 to put on a stand and rebuild so I dont have to pull the motor out of my boat and be rushed through the rebuild. I'm basically looking for a tired motor that doesnt need any crazy machine work. No rod knocks or spun bearings. Let me know what you have!
Thanks,
Jesse

I have what you are looking for. two different blocks one is 30 over the other is 40 over. motors are apart already I also have two different heads, one pair is oval port the other is square.

where you located I have 10 good gen 4 motors and over 20 gen 5 & 6 454 SOME STEEL CRANKS ALL 4 BOLTERS IN IN CA
