So his is what I have been told by builders the hemi is what you wang when your running stock hemi class. Buf when your running stock appearing where they change everything on inside you want the non hemi. The hemi is hard to find due to most tracks around me are promoting a budget race for racers. I searched for weeks to find hemis at harbor freight and after 2 weeks I was told they would have 5 on a Thursday sent my wife to get a couple and we weren't the only ones waiting to get one. There a good motor for a 100 bucks even after the top plate springs fuel pump and pipe you still under 300 with the cost of motor. When if you run a competitive clone motor your easily over 1000 dollars for a good dynoed motor.
