But IIRC the 70mm where basically mustang TB, and we lose CC with the 70MM only if I remember correct... But I just went over this in a recent post, you will not gain and TQ/HP with a TB upgrade because the inlet on the manifold is restrictive, some people have ported the inlet side on the manifold grants more air is more power but, the actual gains <shrug> who knows maybe its only 1-2 hp/tq! No one done a dyno back to back and within 1-3 hp/tq might go unnoticed
176WHP/147TQ Running Rich at flat 12! More power to come once finished!
