Has anyone played with one of these. I have read up on the differences between the 53 series motor. Sounds like a different head with the CC in the head and different liners as it was purely a scavenged motor. So why exactly were the blowers flocked with felt? There is one for sale near that just needs the blower flocked. I know from what I have read that parts are non-existant but I was just day dreaming of a future project beyond my current projects of a 4-51 turbo'd in a pickup. I did read of a guy who had a turbo 4-51 in a truck and it ran like a beast so they say.
