I was at El Camino swapmeet a couple of years ago.
I made a comment to a guy I was talking to.
I said "I rode with a guy once who had a ULH 80 inch chopper.I couldnt believe how massive the heads and barrels looked on his motor."
The guy said that a UL 74 inch motor's heads and barrels are the exact same size (outside diameter) as a ULH 80 inch.He said just the bore and stroke is bigger(or longer). So he said he could use 74 heads 74 barrels(bored) and it would be exactly the same(of course with a ULH bottom). Is this true???????????? Thanks!!
