hi everybody again. i have a 81 bu that has about a 250 hp 350 with a turbo 350 trans. i was planning to put one of my drag race 350 trans. in ,but came across a 200r4 from a 85 mc. that has about 5000 miles on it. it came from a very reliable source and has the stock lock up conv. later on this summer i will put in my 375 hp 350. i would like some input from the 200r4 guys as to the extent of modifications to help this trans. survive under these mild engines. the rear is 3:73. i have been buliding turbo 350's trans. performance and race for about 15 years, so i have a little exp. on some trans funtions. but not the 200r4. from what i have read so far i was going with the hardened stator support, better accumulators,betrter rings for the pump,bigger fluid drain back holes, and i would like some opinions on the constant pressure modification thats done to the vb and case. also a good shift kit. as always thank you very much for your input.
