i just finished this swap a couple of days ago,87 B2600 pick truck,we used the stock tranny that came with the truck,stock driveshaft,S4 bridgported motor,RX7 clutch and flywheel,truck is running great and the tranny is holding up fine.The second gear is way longer that a stock T2 trans,third gear feels like my S5 T2,fourth feels a little shorter than my S5 T2 and fifth is just a dead gear no pull at all.
