Sorry I cant get the dyno sheet to post but, it was pulled to 6500 rpm. made peak 634 H.P. at 5700 Rpm, 650 ft. lbs. torque at 4600 rpm.



peak at 5700 sounds a little low to me.
Maybe the heads are not ported?



or just not enough camduration. hard to tell anything without knowing the whole deal..
