Engine swap

I assume the 305 SB is out of a mid 1980's Camaro or something? If so, you are going to need to alter your engine mounts to fit the new engine. Your 4 cylinder mount locations will not accommodate the larger engine.

Also, you are going to need to alter transmission mounts not only due to a longer and larger transmission but the manual transmission has different mount locations.

Then once you get the drive-train mounted, you are going to need to wire and plum the engine. New radiator and fan shroud will need to be fitted.

Clearly I am leaving a lot out like a custom made driveshaft due to the length being changed, you will most likely not find one the proper length. However, just these few items are large items and will require some pretty in depth fabricating. It can be done but it is not going to be remove one engine and just bolt the other engine in so you will want to plan this all out before you jump in.

I am sure some of the other guys will jump in with some obvious things I am missing. Thanks
