Is there a way to tell if my 72 has dome pistons without removing the head? What year did they start the dome pistons? I tried doing a search but couldn't find anything.

Re: Dome pistons
Thanks, my engine must have been replaced. It's serial is 249945 so I'm guessing it's flat top pistons.

Re: Dome pistons another question
Ok my motor needs rebuilt, so, I assume that the high domes will work. Right? Is there a reason not to use them?

Re: Dome pistons
they will work, just double check head clearance, if the head has been shaved in the past sometimes just need to sand a little of the dome

Re: Dome pistons
Somewhere along the way I've read that the connecting rods are different. Someone like Jim Becker can probably tell right away if that makes a difference if you're changing to dome pistons.

Re: Dome pistons
the rod bearing width was changed so the rod was changed, flat top and dome style interchange, have done this many times

Better to take a little off the head if needed. Keep the moving parts in balance.

Re: Dome pistons
the connecting rods are different. but it will only matter if you are trying to connect the wider bearings to a newer crankshaft THAT HAS NOT BEEN TURNED. the problem is that the wide bearings will lock up the engine due to the radius of the edge of the crank journal.
if its been turned, they tend to cut the radius out.
so, the rods can be used on either piston, but be careful of the crank rod journals.

Re: Dome pistons
so my original rods and crank will work with domes, even if I need to get the crank ground?
