The #'s look good at 6,100!

Is that a stock 289 crank, or did you find an aftermarket one somewhere? Those #s are friggin awesome, especially for such small cubes! Any details on the cam?

Definitely sounds like special rules are in force here!

You don't see too many aftermarket aluminum blocks filled with 289 stroke cranks, wearing iron heads equipped with stock cast iron rocker arms!

Sounds like you're pushing things to the limit!

Good Luck!

Thanks!
