I wanted to put a 700R4 trans in it. He talked me out of it. This was likely the early 90's...
He had been pulling TH350C's out of oil field pickups and install I got TH 400's.

He built me a nice lockup TH350. I had to install the brake switch used on cruise controls, so the converter would unlock with brake applied. There was a vacuum switch that I installed in line with the brakes switch, I unlocked the converter at full throttle.
My TH350C allowed me to cruise at 350 RPM's less....I liked it! Of course my engine builder did a great job on the trans! Wish he had not moved and changed his business focus.

I no longer have the old Chevy, but still have the engine and trans. Still have the Pontiac trans too....
Very cool story! Thanks for the RPM info too !
