big block swap

[xCLIFxCATx]

i just bought a 74 3/4 ton pick up it has a 350 in it but i have a tall block 427 i want to swap in i was just wondering if the engine mounts are the same or if im going to have to get new ones also if there are any mods i will have to do other then trim frame a little for headers

mounts the same. and you should not need to trim frame. dont forget tall deck needs specific brackets for drive acc like alt and stuff. plus tall deck dist needed also.

yah the engine is complete and everything its coming out of my dads c30 work truck so it has all of the brackets and dist but to fit the headers he had to trim the frame perhaps that was just because of it being 2wd
