Can’t recall gears off the top of my head. 2.73 maybe? Possibly 3.23. Not sure It’s an 8.25 from a roadrunner that the previous owner put in.
Compression is a best guess as well. 10:1 presumably once I get these aluminum heads on.
You got gears and stall for mild cam and cr for a larger cam, your gonna need a cam least big enough to run 10:1 and pump gas, probably gonna need more stall and possibly gears down the road.
