Differences between 327/300 and 327/365
Just for my own information, what are the differences between a 365 and 300 HP engine? I know that the cam is different, the 365 has solid lifters, the 365 has a Holley vice Carter AFB. Other than that, what else is different?

Intake, valve covers, oil fill tube, idler pulley, tachometer/redline, (HP, obviously)...I'm sure there are other differences I am missing....

From fan to air cleaner to clutch, it's easier to list what is common.
flywheel
starter
pilot bushing
engine assembly bolts
gaskets (most)
thermostat
plug wires
plugs
distributor cap
points/condenser
spark plug shields
oil pump pickup screen
fuel pump (?)
exhaust manifolds
fan/clutch
alternator, in some cases
rocker ***** and adjustment nuts
alternator mounting bracket
bottom radiator hose
crankcase ventilator
valve locks
oil filter and cannister
piston rings
valve seals
timing chain and gears
oil pump shaft
distributor hold down clamp
alternator brace
starter brace
I'm pretty sure the original OEM connecting rods were different also. The SHP engine block was different in the respect that during engine assembly, it had a swatch of greenish blue paint on each side of it to flag it as a SHP block assembly.
That's about it, give or take a part or two. What did I leave out?

I think you'll find the crankcase ventilator (if you mean the tube from the rear of the block to the aircleaner) and fuel pump are different. Nice list, by the way!!!

Thanks. That list was longer than I first thought. I edited it about 6 times.
"Crankcase ventilator" is is GM nomenclature for the tomato juice can under the intake manifold that baffles out the crankcase oil from the the blowby.
