Hi and thank you for your help and thank you for a very helpful site.
I plan on swapping a 4bt into my '82 GMC step van and would like any advice/suggestions to speed up the process and avoid any setbacks.
It currently has a 292 (4.9) I-6,4 speed stick,4:10,16.5x9.5 wheel tire combo,power brakes,manual steering & weighs 6,880 with me in it.
Currently used for ice cream vending,80% of the time 8-10 mph but I need to travel on occasion at 55.
I need to make it more fuel efficient and nimble so I also plan on rebuilding a TH 3L80 with straight cut gears and change the 4:10 gears.
Any advice on the rear gears,what pieces/components that I need to swap the trans and any advice on swapping in the 4BT?
I've been looking for a complete donor but no luck.
Thanks again to any one that can offer any assistance.
