It looks like it will stay a 347 as it will just need a hone to clean up the bores. This means I'll be keeping the current rotating assembly..
The final wash up was the crank turned out to be a little tight. So a new set of bearings throughout and a hone is all that is required. Also they suspect the bores weren't cleaned up properly after it's initial machining and it wasn't plate honed.
The machinist said this is all pretty unusual for a dart short block.
No sticking with the current cam for now. When I took it out there wasn't a mark on it. If I go for a bigger cam with those heads and induction I could see a new drive train in the near future!! This cam will limit the motor to 420HP @ 6200.
This time I will run the motor in with HDD magnets on the sump bolt and oil filter!!
