I broke my 4l60e yesterday and want to swap a t-350 from my race car question is are they similar in length? Can I modify the original crossmember to work? I already have a bmr tracpac that moved the t-arm back so its the drive shaft im concerned about Its new and custom made 3.5 inch chromemoly will it need to be lengthened? Anything else to be concerned with? I have a new transcooler b&m prostick and the trans is fresh with a cheetah reverse pattern valvebody with a trans brake.Please help.

 

A TH350 with a 9" tailshaft is the same length, just have to add material to the crossmember, easy job for a muffler shop or any place that can weld.

I recommend the MadMan dipstick tube.

If you want the speedo to work there are options, search and you can find them, if you search on my name they will show up.

I would get a trans temp gauge.

Beef up the rear if T-braking it, 10bolt might not last long.

 

Its got a 9" with a spool

 

Get the TH350 with a 9" tailshaft and it all should be ok.
