I swapped in a 350 Chev, SM-465 and a NP-205 case into my 75 Scout. Was it worth it? HELL YES it's the only way to go IMO. The same could be done with a SBC, TH-350\NP205 combo if you want an auto with NO ADAPTERS and the strongest T case you will ever find.cajackson said:could someone please tell me what changes need to made to put in a chevy 350 in a 78 scout. it now has a 345 with auto tranny. do i need to change tranny,motor mount stands, etc? would it be worth doing?
