Crank choice for 2.3 4g63 build
I am ordering a 2.3 shortblock but cannot decide which crank to go with. What do you guys suggest? Is the 4g64 crank good enough for 8500? rpm Aiming to hit around 650-700 whp.

I ran the Manley billet crank and set the rev limiter to 8600 rpm. I would intend on shifting at 8400 rpm, but found I constantly hit the rev limit when set at 8500 rpm. I made over 100 pulls at 45ish psi on a 6466 making well over 800hp. If the engine is built well and balanced, it is unlikely you will have issues. Buschur mentions on his sight that his 2.3rpm engines have done track passes to 9500rpm, and rated for 8500rpm.
