Have a friend who is converting a really sweet 91 D100 shortbed from a leaning tower of power 225 to a 451 low deck BB. The question I have is do all of the trucks share the same frame mount and only require the engine and motor mounts to go to a big block?

Anybody have a good source on the mounts needed? I would assume either 383/400 or 440 mounts from 71-93 would work?

Sorry, I am not as sharp on this stuff, the last swap I did was back when they had different engine mounts from a 273 to a 318 to a 360, and I remember wondering what the heck were they thinking........

 

the frame mount's should all be the same it's the Engine mount's that are different

 

my '74 ramcharger has 2 mounting points, at the cross member and behind that, the additional plate the v8 was mounted to, anyone know what they provisioned the forward cross member mount for? you can buy engine mounts from any auto parts source.

 

OK, I was wrong evidently, a 91 has the 3.9 V6, not the leaning tower of power, so I would assume the V* mounts will work, now how about the block mounts? Looking at the motor mounts, the BB looks like it has 1 stud down, 2 studs up like there is a L plate or something on the block? Does anyone have a picture of what I am looking for or a source where I can find a pair? ( engine side adapters to bolt the rummer mount to the engine )
