Does anybody know of what all parts should be replaced in a motor swap?
I'm planning on buying a 350 out of 87 k30 and puting it into an 84 k10 that currently has the factory 305. Will the flexplate swap over?
the 305 has:
new starter
new alternator
newer fuel pump


I am trying to get a list together so I don't have to run to the parts store every ten minutes.

Motor Mounts
fuel pump
oil filter
fuel filter
antifreeze
gasket set
thermostat

Man, as cheap as they are. I would put a new water pump on to. One with a live time warranty. Check the freeze plugs while you got it out. Just in case.

flex plate may be differnent as far as size of hole to slip over crankshaft in rear . measure it . otherwise they are fine . otherwise the 87 will be tbi if not mistaken so you will need electric fuel pump, careful on water pump as serpitine set up is different and manifolds man be different on rear hole from a 350 to 305. those issues cropped up on my 86k5 swap.

Yep, '87 is the first year of TBI fuel injection in trucks. Need 13psi fuel pressure.
