Ok so I am new to the flathead game... (so be nice to me please) Picked up a few this past weekend. I am building an AV8 frame to drop my '26 roadster on. First is a 46-48 59A and runs smooth and was in a welder generator its entire life...! Second is also a runner out of a '53, has spun bearing ($80-150 fix). New carb and 12 volt conversion. Was his daily until bearing issue. Seller states was rebuilt around 6k miles ago.. super clean inside after taken the intake off. Not sure why the bearing spun so soon? 3 speed side shift with one heck of a loooong tail shaft! Is there a short tail shaft that fits? Ok so my Question(s) to the gurus: Which flatty is best for the AV8 build? The '46 59A has the fan sitting real low off the crank so is there an easy way to move it up say off the generator/alt location?? Oh I have 40 juice brakes and a '35 banjo going under.. stock A axle with reverse eye spring and small Doane Spender kick up. Thanks, for any feedback you ca provide.. .
