I know that it would be a pain to install a 454 into my 78 3/4 ton pickup or would it? right now it's got a 350 c.i and would like to use a 454 for towing a boat or anything else that I can get my hand's on.What i'm wanting is some serious torqe and horse power ,or how it;s said there's no subitution for cubic inch's.Anyhow thanks for the time into reading this letter .So have a great chevy day Michael:burnout

There is lots of room for a big block in that 78:D Only thing you really need to do is move the motor mounts forward, and get a bigger radiator. I am not sure about the bellhousing on the big block compared to the 350, but i think they are the same.

A big block will drop in with absolutly no problems, dont need to move mounts and the bellhousing will work fine.

radiator may be big enough

I would replace the motor mounts with fresh ones just since its easy to do with the motor out and they are probably 1/2 shot.

do a search and you can get a complete list of what will swap(like dist) and what wont swap(like some brackets) and you should be able to peice together all you need for the swap.

The big block is an easy drop in after 73, brackets will be differant so find a doner for them, you'll like the big block, it just feels good, older chevys require some custom mounts and some frame carving, but otherwise there is plenty room for a nice four row, will need to find a fan shroud from that doner vehicle as the big block shroud is shorter due to it sitting closer to the radiator, with casual drivig I actually picked up an extra mpg, it handles the 36 inch tires much better.
