Location: Tonopah, NV (actually 60 miles east) | Good morning all ....
I'm trying to put together an Excel spread sheet to figure out how much I may need to spend getting my car done. It's basically a comparison of what I know I need to do vs what I'd like to do. I'm working engine costs right now and was wondering if anyone here knows if a 331 Hemi intake will fit on a 331 Poly engine? Also what are the differences in the 331 poly engine to make it a 250 Power Pak? I was just thinking if I'm going to end of doing a lot to the engine I might as well make it get a little better performance while I'm at it. Can't hurt the gas mileage ... I had no idea you could dump a gallon of gas through a 1 barrel stromburg in 12 miles. I'm sure the carb needs work anyway!!

The Poly was the only way that one could get a 1956 Windsor from the factory. The 4 bbl'd Power Pak option was a goodie from Crashlier that had dual exh to the rear ( first year on what to be known as the infamous MoPar tail pipe hook. The transmission was the H.Duty version that was a standard in the Imperial Division and used by the Chrysler New Yorker or 300B's. The rear axle also had the same big boy spec's.
Just before I had my stroke I wanted to get a 1956 Windsor that had the OEM 250 Power Pak. I even went as far as getting a dealers brouchrue.

Location: Tonopah, NV (actually 60 miles east) | Thanks for the quick and as always knowledgeable reply Rodger. I didn't think the 250 option could be much more than a 4 bbl and perhaps different valves and cam. I made a Boss 302 out of a 289 with 351 Windsor bv heads, different cam and a 4bbl intake ... just as much HPfor less $$$$.
How much of a recovery have you made from the stroke so far? If I get over to visit my nephew at the USAF Academy I'll have to swing by for a visit and bring the Windsor.
Thanks again,
Doc |

When I want to work on the vehicles, I find that I lose my balance when my head is tilted. I now must wear reading glasses if the work is detailed and less than eighteen inches. For the lose of balance the neurlogist told me to carry a cane at all times. My wife gets Dollar Store $1.00 reading glasses for me to leave every where I stop at now.
Since I am not as active as I was, The weight has gone sky-high.
It is a differant world now. They will never let me re-new my pilots lic, but that is OK. I'll never run a 5:50 mile again ( & I could at 55 ), but that's OK. I am still able to get up in the morning and talk about cars, boats and planes though. That's OK.
My hand strenght has gone from a left of 128 lb's per sq in to 106. The right has gone from 130 to 108. The first test was just after the stroke and the second was last Friday. That means I can still pull a torque wrench. Just before this happened I could brench press my own weight or do ten one arm push up's with either arm. Now it takes all I can do to get out of the chair. That's OK since I can still do it.

I have been told by two sources here on the FL that at the end of the production year, a few of the Windsors that had the power-pac option, got the 354 Hemi My 56 Windsor had the power pac option.and was a late in the year production. It sat in a building for over 30 years without an engine in it.. hhhmmmmmm? I sure would like some more info about this option........................5%.................... |

Location: Tonopah, NV (actually 60 miles east) | Hey Steve,
I wish I could say I knew the answer to this but I haven't ran across that information yet. Everything I've read states the 331 poly was the engine for the Chrysler Windsor for 1956. My car is an early 1956 (W56#3745) Detroit car making it the 2744 car made on that run (since the VINs start at 1001 and go through 75206). I guess your best bet would be to get the IBM build card for your car. I'm going to do that as soon as I get time to get the title changed over to my name. Does your car still have the trasnmission? The 250 Power Pak would have given you a heavier duty transmission and rear end for your car. Also I don't believe the 354 used the same transmission so depending on what you have transmission wise it may help you identify which engine your is supposed to have. The 1957 or maybe 1958 got the 354 basic hemi engine but with Poly heads. Most things I've read say the 331 poly is basically the 331 hemi with minor spec changes and different heads. I had considered converting mine to a hemi but the cost of parts really don't make it economical for the horsepower gain I'd get. I just want to get a bit of an HP gain since I'll be spending a few bucks on engine work anyway. If mine had come minus an engine and I wasn't worried about making it original I'd go find an old 413 wedge or comparable motor (383, 440, etc) and do a full drive train swap. Make it a factory "looking" sleeper as it were. I still have two cars I'm dead set on building in my lifetime ... a Superformace Shelby Cobra kit car and a 1965 Lincoln Continental convertible (slightly modified of course). I'm sitting on an original 427 side-oiler for the kit car and I my brother has an actual F&%d Boss 429 engine. He's getting a bit too old to play with cars and next trip I make back east he said he'd sell it to me.
Cheers,
Doc |

Location: Farmingdale NJ | Well, if you guys cant find the info, I've got a 331 Hemi. I would be glad to make any measurements that you need. If you have a poly, we can compare the numbers. .....besides, didnt this subject come up before? I thought we talked about it. Maybe it was a different combination....................I dont know |

The HD PowerFlite was used from the heavy tonnage of the Imperials to the Super fast Crashlier 300 ( 331 cubes ) and the following years 300B ( 354 cubes ) or the just as fast De Soto Adventurer ( 341 cubes ). This fits right into the 1956 Windsor with the Power Pac poly'd version of the 331 that we are speaking about.
Up at the Impeial Division, the Crashlier New Yorker, the 300B and the De Soto's all went to the TorqueFlite as the only transmission after May of 1956. And that was the last of the senior vehicles to show the PowerFlite in their books.
In the lessor vehicles the PowerFlite went on to the end of the 1959 production year.

You are correct that the Chrysler New Yorker and the Imperial got the 3speed Torqueflite in late 1956.
The DeSoto unfortunately never got it. I think it was reserved just for Chryslers and Imperials until 1957, with supposed exception of a FEW Dodge D500s (unconfirmed rumor).
I am presently putting an A466 Torqueflite into my 1956 DeSoto Adventurer, since this retrofit kit WAS available to dealers to install if the cars had issues with the Poweflite transmission (like breaking CRANKS on hard downshifts!).

Location: Tonopah, NV (actually 60 miles east) | Hey guys .. thanks for all the insight and I hope I'm not repeating a thread by posting my engine question. I just found a book on the internet at Victory Library called "Chrysler Poly Performance" .. it supposedly covers an array of performance things for the poly motor as well as some history. If it turns out to be useless it only cost a tad over $22 with shipping.

JerseyBob ... I very well may take you up on your offer to make some measurements. I really have a need to fit a 4bbl on this Windsor = )
Thanks again,
Doc

Location: So. Cal | I am almost certain that the intake manifolds are the same for the Chrysler hemi and poly.
So all you need to do is get one from a hemi motor and bolt it on. |

Location: Ontario,Canada | Docplez, I have a 1956 windsor convertible with the powerpac option. I can check the intake for any casting numbers to see if they are the same as the hemi, if this will help. Let me know. |
