Got a 478...

[Prowbar]

Always wanted to get a bigger V6 than the 305 that I now have... Yes sir I found one. To find one of these in the Netherlands, especially a 478, is a one-in-a-million chance...

A standard, non magnum 478. Complete engine with new gasket set, although in parts at the moment. With all the large truck accessories, such as bell housing, flywheel, clutch, air compressor, generator, brackets, etc. If you're looking for large truck accessories I'd be happy to help.

The engine is in very good condition and looks to be a fairly low mileage engine. One of the exhaust valves is burned though, will need a new one for that, or have this one repaired.

My plan is to build this engine to replace the 305 that is now in my 1500.
It will be a stock rebuild, with a couple of minor modifications.

I've been studying Bigblock V6's posts on his 478 swap, but still have a couple of questions. If we could come into contact that'd be great!

The plan is to convert the engine to use all the light truck accessories, such as the bell housing, water pump, and timing chain.
Will have to fab up a flywheel and have it balanced.

My guess is that the engine is a 62, one of the first 478's. No PCV valves in the head, but does have the fresh air canister on the back left side. My guess for a 62 is the fact that it came with a generator instead of the alternator.

Your thoughts?

Thank you very much Lewis! Checked out BB V6's profile, seems like he hasn't been active on the forum for a while.

Correction: there are PCV valves in the heads, and I just found a replacement exhaust valve in one of the boxes! Couldn't be happier. Here are some pictures:

You will sure like the 478. I drove one for years in a '62 6500.

Sure is a powerhouse.

Been chatting with Pete on messenger, will ask him what's going on.

Cleaned up the major grime off the heads. Removed the valves, no surprises. The valve springs are pretty stiff though. The guide from the burned exhaust valve needs to be sleeved, as it has more play than the others.

I will also have the heads professionally cleaned, decked and have hardened seats installed in the intakes.

The castings, as from the factory, are pretty bad regarding port design. The exhaust passages faily are restrictive compared to the intakes. But the worst thing is the short turn into the into the head has a very sharp ledge above the valve seat. I am working to radius these to create better airflow. Both intake and exhaust have these sharp ledges. Also the exhaust ports really need to be cleaned up, they have ledges in them. I removed these also.

I also lightly broke the sharp edges in the machined combustion chambers.

That's as far as I'm gonna go with the heads.
