I put my springs in a while back. I watched what they will do and such now I am just wondering this.

I can rev to 4000 and that is fine. If you are driving it will pull hard to 2500 then it seems like like you over rev it past 2500 and you need to shift.

My question is what do I need to do so it will pull hard to 3500 to 4000 rpm?

thanks

 

Have you had any transmission work? Valvebody?

Have you checked your Gov Arm to Plate clearence?

 

Yes the valve body and trans are race ready.

 

Could be a issue with valvebody tuning, also could be adjustments needed in the pump
