turbo 350 trans

Hi Im putting a 308 turbo pattern red motor in my ht its got a 253 trimatic in now.

Does anyone know if the turbo 350 trans is the same length as a holden trimatic or will i have to change tail shaft and crossmember.

What do you think would be the best way to go.

Thanks Terry

The th350 is longer by about 3inches than the trimatic and the mount is in a more forward position than the tri.A Chev Powerglyde will bolt straight in(with only a speedo cable change!) but you might miss the extra gear!
What are you using it for?Going to be doing any racing or is it going to be a bit of a weekend worrior-cruiser?
Get the box overhauled by a competent transmission specialist-and get the sprag changed to a steel one-throw the cast jobbie out-they are the weak link in the TH350.

Don't know where you live but why don't you have a decent auto trans mob rebuild you trimatic.Yes they were prity useless as standard but there's a few decent rebuilders that can rebuild them prity tuff.I'm from Perth and there's a place called Welshpool automatics that can rebuild them.

Fitzi,bit of a pain behind a turbo block! But I agree. I've had them built by Welshpool autos,Chriss Dimoff(DTM) and Versma,they were all just about unbreakable when used propperly!(read that as no rollbacks and fishtails with open centre diffs)
