i own a 88 camaro that was originaly a 305 tbi and swapped it with a 350 out of an 89 z71 pick up. the original 700-r4 lost 3rd and 4th gears so i bought a turbo 350 trans wich i was told from an 79 or 80 car with a 454. it has a long tail shaft and i believe mine has a short one. can they we switched or buy a new short one to replace the long one? and will the trans match up with the motor? also the motor has a hesitation in it it still runs decent but sounds bad,and loss of power i was told it could be the oxygen sensor. any ideas? i appreciate any input, thanks

You can tear the tranny down & change the shaft & the housing or cut your driveshaft down. It will bolt up just fine.

I almost forgot, you will also need an adaptor for the arm that comes up from the rearend. B&M sells them.

As for the trans - if you're going to have the output and tailshaft swapped in a TH350 I would personally rebuild the 700R4 and sell the TH350. Having OD is awful nice and you can run some steeper gears in the rear...
What engine computer and injector setup are you running? If it's the stock 305 you might look into getting it recalibrated for the 350 engine. Also - pull the engine codes and see if there is anything being reported - this can be done with a simple jumper wire and it'll flash out on the check-engine light - there are plenty of web sites out there to describe this so I won't go into it here.

you can buy a switch kit that has a different shaft and an adapter to make it the same length as the 700.If you don't know how to rebuild it yourself and have to pay for it might be cheaper to get a drive shaft made.As brian said the computer should be the one that was with the 350 and the throttle body if it bolts up. I think there was 2 t-bodys different cfms.
