I did the T56 magnum swap in ACE23 Superformance recently. The work required would be the same big block or small block. Requires moving the cross member back and lower, a modified shifter to center shifter in tunnel hole and a short ass driveshaft! Will do mine soon. I love the T56 so much better than the TKO’s!! As far as 1st and 6th worthless talk to someone who has done it. We put 4:30 rear gears and 325 tires. First gear is equivalent to my first gear with 3:46 rear and he can cruise at 75 mph in sixth gear 2500 rpm.
