I'm intrigued with the stated improvements the 700R4 and variants but not sure of the cost vs benefit of swapping out a '71 TH400 for a 700R4. The 400 has no issues and finding a good take off around here would be difficult. So hijacking this thread, opinions? Leave it alone, keep the 400?, locate and rebuild a GM?, or purchase new and cross the fingers. Its a truck, I drive it, no heavy trailers or stoplight cruising...

TH400's go until they don't & are fairly HD pieces of equipment. If the current one works & you don't drive on the highway multiple times a week or take extended trips there's not much benefit to changing away from one.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
