Can you identify this engine?

Can anyone identify this engine? It is in a 1966 Coronet.

I agree 318 poly

Looks like a 318 polyshere A engine.
Apparently the upper radiator hose didn't make it run any better.

Don's correct. Definitely a 318A Poly. These engines will run forever if properly maintained. If you want to know more go to Polyspherical AKA Poly 318 on Facebook. There are also a couple POLY owners here, like myself.

Agreed. But I’ve not seen the heater hoses on that side of the engine. Looks like your heater core goes in on the left. Interesting.

Or keep it and re-build. Great reliable engines, although I may be biased...

 

[Darter6]

Me too

I think a stroker poly with a hidden nitrous setup in a 62-65 b-body four door could be the greatest sleeper in the Mopar world!

Except for dizusters raggedy 62!

I’m with you. Didn’t cost that much more to build my Poly. AND I like hearing, ‘what is that?’ Even from some MOPAR guys. Bore it .040, drop in a 4” crank and it will give any 440 all it can handle.

yep

Loads of potential in Poly 318's, not too hard to stroke.
