77 Chevy Engine Swap

[Abishai]

Ok I am new here so if I get flammed for this, oh well.

I have a 1977 C10 Custom Delux Chevrolet Fleetside Truck.
It has a L6 4.1L 250.
I was wondering how hard it is to switch the engine to a 350?

If anyone has had any problems please let me know.

you need a donor truck or trucks to cheaply donate whole assemblies.
shroud, mounts,engine wire harness, radiator, ps pump,exhaust,etc.
without that all the pieces can add up bucks and time fast.

I'm new to this to. But i would think there would be a problem with putting a 350 in place of a 250?! The 350 would be larger and I wouldn't think the motor mounts would line up. I would appreciate (for my own knowledge) if you would let me know how it turns out. I'm quite curious!!
