Well..........I guess I've bumped my head but I'm gonna get rid of all the stuff I've accumulated to build a big inch Max Wedge engine and I'm gonna build the Poly 318 instead. I know the power level won't even be close at all but its different ( lots of folks dont even know what one is ), and its less work because I dont have to change motor mounts, transmission, driveshaft or anything else. I know its crazy but I like different and it should be pretty simple. The Poly engine is an interesting piece. I'll update with pics on what we do and after we dyno it I'll post a dyno sheet. Need any big block parts ? LOL

Watch Chrysler Power magazine. They've got some guys that are really hot on the Poly deal....Hot Heads is making some good heads for them. There are also some good cams available, and some good intake/carb combos. I think it has a lot of potential. www.chryslerpower.com

There are no after-market poly heads.

JC, send me an e-mail jlemire426@gmail.com I will send you photos of the poly in my 67 Valiant that I just drove trouble free from Indiana. It's no tire fryer but it does make impressive torque. Gary has everything imaginable for polys and is trying to talk me into a stroker version but I have me mind set on a 408 sb with a blower, after all, it's only a street car. I am planning on running my car at Fontana soon to do a before and after so when I do I will post the times. Joey

Exactly. I'm not trying to build a race engine. I work at a race engine shop....all day, every day. If I wanted 1200HP and 900 ft lbs tq......of course I'd choose a different combo. This is gonna be the simplest,least expensive and quickest route to be out cruising......and guess what....DIFFERENT....imagine how many folks will look under the hood and say " what is that ? " It will sound real nasty, still have over 400 HP and 400 ft lbs TQ....if not, its no biggie....
Thanks for all the input. I do appreciate it.

For what it's worth, I pulled into Bob Mazzolini's shop and opened the hood and it took him a minute to recognize it and then we had a good laugh,
it is different,like I stated in another post, driving half way across country in a 4-speed A-body with 3:23's it averaged 14 mpg and approx. cruising speed of 68-70, the engine has ported heads and intake, completely stock bottom end and a Scneider solid lifter cam.
There was a guy at the Riverside California cruise in a couple of months ago with a poly with twin throttle bodies and electronic fuel injection, very cool car.

I remember years ago Mancini had some headers for Poly heads in their clearance section maybe they still have some left The heads look like they could flow with some work but then you mentioned you were building a basic good running street so flow numbers at low lift should be easy to attain. Every once in a while an aluminium intake pops up on Ebay. Did RAS make rockers for them Gus

Is this 318" the same engine family as a 1957 354" non Hemi engine?
