Scat 383 Crank And Trw L2491f Pistons
well today i just mocked up my cylinders for clearencing, and everything cleared without a hitch.....
the pistons came close to the crank throws that are the thickest but were plentey enough cleared for the others...... i had about 1/4 clearence on the pistons and even heat expansion wouldn't be .050 less.....
i know that there was a few people that had problems with these pistons but i'm glad to say everything came out fine....
now on to balancing!!!!
p.s. thanks to smasterson, and the rest that gave me the heads up on this prob!!!!
