Technical such thing as a 392 hemi industrial?

Actually the plan was for the NYer to get the long tails & the NYer Deluxe & Imperials to get the short tails in '54.

 

In '56 the Poly would have been 331 & I think the extra small holes with the pushrod holes indicate it's for a Poly, Some have speculated that 354s bored to 331 may be warranty replacement engines.

 

No idea of what size this one is but it's kinda cool. It has sat out in front of a local wind machine manufacture for years as their lawn ornament. No doubt it did duty in an orchard for a number of years.

 

An easy way to paint the raised letters on valve covers or license plates is this. Spray the letter color with base coat and then clear coat it. Then spray the field color with base coat and take a rag with reducer and wipe the paint off of the raised letters. You can finish the tricky parts of the letters with fine sandpaper, just don't sand through the clear. Then clear the whole part and you are done. Here is an example of a Heintz Gullwing pop cooler I did. The raised part said Pepsi-Cola.

 

Always thought these were cool too.




How would you like to be the guy that had to R&R two iron hemi heads on this one.

 

All I have ever heard or read is only 331s and 354s were used for Industrial engines. And that 354s were by far the most prevalent. I have never seen a 392 in that use.

I am really intrigued by truck heads for hi-po use, especially for 331s that have no end water ports. Neither do the truck heads. That makes them attractive for drag racing engines which don't use those passages and need them blanked off.

Benefits I see of truck heads;
big exhaust ports
hardened exhaust seats
big valves
no crossover water ports
no exhaust pre-heating passages

Negatives for truck heads:
have fat sodium filled valve stems, need new guides.
have tall hot water intake manifold passages, don't work with passenger car manifolds.

Here are pictures of truck head features
No water ports in ends


Big ports, hardened seats


No Siamese heat riser exhaust passages in exhaust ports



Big exhaust ports


hot water pre-heat port too tall. Easy to fix by brazing in a partial blocking plate

 

Here is a few more pics of the marine heads even though I was told is came out of a truck. The tabs from the intake seem extended to cover those center ports.

 

that's the truck intake, the marine intake looks bolt together. I have truck heads with the square crossover instead of tall.
