78 Correct Craft Southwind Engines

351W heads have 4 bolt valve covers, 351C have 8 bolt valve covers.

Valves in 351c heads are arranged inline, like a small block chevy, 351W valves are staggered like a big block chevy.

351C heads used regular flat sealing area spark plugs, 351W heads use 14mm tapered head plugs (peanut plugs).

The timing chain recess is part of the block on a 351C, the timing chain is in a spearate bolt on front cover peice about 1 1/2" thick on the 351W.

The machined face where the water pump attaches to the block touches the face of the block where the head bolts on in a 351C, there is a gap of about an inch between that flange and the top face of the block on a 351W.

The 351C hads the thermostat mounted to the front of the intake manifold, and water passes thru the front of the intake to get to the thermostat. A 351W has the thermostat mounted on the top of the separate timing cover extension and cooling water goes straight into the front of the block thru castings in the timing cover, and bypasses the intake manifold. So if your thermostat housing (with the hoes to the exhaust manifolds and from the raw water pump) bolts to the intake manifold its a Cleveland, if it bolts to the timing cover extension its a Windsor.

Well, here are a few pics. Sea trial yesterday after getting all new parts bolted on. Made it around the lake, she didn't like full power, but kept her low to break her in and let her stretch her legs after sitting for so long. It was exhilarating! I never thought this old girl would ply the waters again. Had a few minor tweaks, readjust packing in prop shaft, and tranny fluid needed changing. 2nd sea trial after adjustments went worse. Tranny fluid leaked right out of her. Ugh.

So, now I'm seeking input on changing seals. I haven't pulled her apart yet, but I'm suspecting it's the front seal on the tranny that needs replacing at least. Are there other seals I should be checking? Can I pull the tranny without pulling the engine out? I'm trying to get this done quickly so I can get her back out on the water. Thx for your help!

Is there a way to test the pump to verify if it's actually in need of replacing? I was going to start with just a seal kit. But have been reading some of the threads on CCF about worn pumps blowing out the front seal. Would a regular auto tranny shop be able to fix this?

Any info on FFI Transmissions available? Couldn't find anything on Google.

thx!
