Filling blocks

Re: Filling blocks
I worked on a pulling tractor head that was filled with bronze. Worked well and was able to turn the diesel ports into blown alky ports!! I imagine they had had to pre head the head to a glow before they poured in the bronze.

IIRC the calculation we did, there are 175 linear inches of sleeve mating to block.

Re: Filling blocks
After fully furnace brazing the sleeves into the block, I don't see how there could have been any leaks.

Re: Filling blocks
I wonder if anyone has ever tried threading the bottom of the sleeve then brazed the top via induction brazing?

I'd hate to be the one to take on that project. Just thinking about doing it gave me a headache.MichaelThompson wrote: ↑Thu Jun 22, 2023 2:16 pm I wonder if anyone has ever tried threading the bottom of the sleeve then brazed the top via induction brazing?

Re: Filling blocks
I believe the Motor City Flathead aluminum block was cast without cylinders and special cylinder sleeves were installed that had threads at the bottom and possibly the top as well. The threads were timed together top and bottom if I’m not mistaken.
Much more straightforward if you’re casting a block to accept such a sleeve. I kind of doubt there is enough material in the bottom of the factory block for anything like that.
