I recently purchased a 4bt and I am planning on swapping it into my 1979 f250. It currently has a 351m backed by a t18. Truck is linked and is primarily used off-road so I’d like to keep the t18 If I can. What is my best option as far as sourcing out an adaptor plate/clutch + flywheel? I have a bellhousing off of a t19 with the 6.9 idi pattern ( at least I believe it is a t19 with it being a 4 speed) if that needs to be used. any help will be much appreciated! Thanks in advance.
