NOT MINE: I have no connection to the guy. Guy in Stanley NY has a posting selling a collection of Hemi parts, just thought I'd pass this on if it's ok with the powers that be. Tried to post link couldn't for some reason. If your interested and can't find this on facebook market place let me know I'll reach out to the guy.
The Chryslers were the most popular for the racers. 392 was the biggest cube I believe. More parts available for the 392 may be.
The 331 and 354's were a low deck and the 392 was a tall deck. Kind of like the B and RB 383 vs 440 engines. I don't know what parts interchange between the 3.
How do I tell the difference between a 331 and a 354? I need a number 3 main cap. It was cracked long ago when it was being assembled. So if I get a new main cap, and a line hone, maybe I’ll be okay for reassembly.
I have 241 Dodge Red Ram that looks good because of the chrome but is nasty inside. It went through a couple floods and was submerged in mud. Anything can be saved but........................
On those, since they are both low deck engines, the only way is by the numbers stamped on the top of the block, just behind the water pump.
Yes. The 331 and 354 are low deck engines, similar to the 383 and 400. The 392 is the tall deck variant, like the 413, 426 and 440. 331 and 354 share the same basic cylinder head measurements, while the 392 heads are all by themselves. Rather than make the difference for the tall deck engine with a wider intake manifold, Chrysler made the 392 heads have longer intake runners to make up the difference. This is why people serious about making power don't use 392 heads. The intake ports and longer and have more of a restrictive curve than the 331 and 354 heads. Lastly, the 54 and up 331 and 354 heads are more desirable, because they have big free flowing oval exhaust ports, compared to the 53 small round exhaust ports. The best flowing early hemi heads are said to be the "555" or "triple nickel" heads. These have three 5s in the casting number. The truck heads also flow just as good, if not better with the addition of the 392 valves. That's what I did to mine.
You da man. You’ll be my go to guy here in a few months in that I’m purchasing a 331 with plans to rebuild it.
I have a 291, 330 and a 341 Desoto Hemis. Always looking for Desoto Hemi parts. I also have two 354 Chrysler Hemis. Thanks
