the ISSUE is the "balance factor".. most late model STOCK fox type cranks are 50 ounce...
all the early "289" cranks were 28 ounce balance.
so you need to get a 50 ounce balance flywheel.
the TOOTH COUNT will fix itself, because if it is wrong,...your starter will not engage and turn over the engine.
so, buy the tooth count that will match the starter / bellhousing diameter.......
I have gone down the road that you are only now about to travel.
tires are the great equalizer
a degree wheel, EIGHT INCH dial caliper & adjustable pushrods should be just as normal as a 1/2" wrench in your toolbox
there aint no shortcuts to doing it RIGHT....
