Alright guys i have a question about a flywheel. Right now in my truck i have a 302 backed with a M5OD transmission. I'm swapping a 96 351w into it. I need help clarifying what flywheel i need. To my knowledge i believe what is in my truck now is a 50oz flywheel with 164 teeth. I think i need a 28oz flywheel with 164 teeth, is this correct?

 

Yes that is correct.

 

Thanks Conanski!

 

just read this and started to think... would i need a different flywheel if i swapped my 302 from my 1992 f150 automatic with a 302 from a 1988 f250 with a 5 spd manual?......... and i pulled the heads to replace headgaskets on this new engine in my truck and noticed scratches on the cylinder wall, not cross hatch, was kinda of a swirl, but definetly not cross hatch, and it was only on the drivers side, any ideas to what could cause this?

 

Auto transmissions use a flexplate while manuals use a flywheel, but since these motors are both post 1981 they have the same balance so you would just need to put the '92 flexplate on the '88 motor.

 

ok... any idea what could of cause those scratches in the cylinder wall? they are just deep enough to feel with your finger nail

 

A broken piston ring perhaps.. or maybe it's just the results of someone doing a cylinder hone by hand.

 

ok thanks ill check it out
