Do you think you could beef one up maybe by putting bigger or stronger bushings and stuff in a quad 

Oh okay well how do you tell what pound rear ends you have is it casted on the rear ends 

So can you fit a maxidyne into a b model that has a quad tri or duplex transmission

On a late 50s early 60s model Mack b81 what does the stamp on the rear ends that starts 64k mean

So even if the block nor heads came with the grooves you can have them machined into them

Okay so just wondering I haven't seen anyone do this yet can you just ,fire ring, the head and block to seal these old motors like you would a 12valve cummins that way you could maybe get 225hp to 300 without blowing head gaskets 👍
