Stop in for a cup of coffee

So I just made a deal to buy a car that has a 66 318 Poly.....makes me regret a little that I didn't pay more attention when you guys were talking about 318 Poly's

Are they worth anything ??

I can for sure get it running but I am not sure I want to mess with it. Seems easier to remove and replace with a 383 or 440

Worth anything? No. Not unless it has the rare factory 4 barrel or even rarer factory dual quad intakes. They're expensive to rebuild, performance parts are fully custom made. They do share a bell housing pattern with an LA block so you can swap to a 360 easily.

Now they are one of the most durable Chrysler engines. The locks are beefy as heck, can be overbored .100 sometimes as much as .120. LA heads can be swapped ok with som pushrod clearance get and water port alignment work.

That said. A run of the mill 318 poly with a four barrel was rated at 275 hp and the dual quad was rated at 295. But they weigh has much as a big block 440.
