Hey all~ I need a little info on the '53-'56 Dodge Poly's. I have a customer that just dropped off a 241 for a BAD A$$ '37 boat project he's working on. 4-71 blower, the whole 9! Anyone know of a resputable location for the simple stuff. Pistons, bearings, seals, etc? Sorry to bother the normal board with this. Mike Engine Monkey
Everything in the block is the same as the Dodge Hemi except the pistons. www.hothemiheads.com Egge has pistons for Polys, don't know if they would have forged for your blower motor, might call Ross or other custom piston outfit.
All polys begin 1955. The 241/259/270 has the smallest crank of any early engine and I wouldn't suggest a blower. The later 315, 325 are preferable. The small engines have been stroked using the later crank, but it's a lot of work. You can use any low-deck Dodge hemi (241, 270) manifold. Only low-deck Dodge parts will fit the lower end. http://victorylibrary.com/POLY.htm
"The 241/259/270 has the smallest crank of any early engine and I wouldn't suggest a blower." The Dodge series of engines are very prone to crankshaft failures due to (IMO) most not using a harmonic balancer. The low deck Dodges also use a very small 1.937 rod journal.
...and speaking of polys. I have a '59 dodge 326 poly and am in the market for a edelbrock P-600 3x2 intake, also finned valve covers. Any help is apreciated. Bart
The P-600's come up on eBay fairly regularly listed as 318 poly. Manifold with no carbs will go $250+. Alan Fountain of Australia makes valve covers which are identical to the original Edelbrock minus the logo. He sells them in the States but lots of your folks whinge about the cost. The last set of Edelbrock on eBay were far from prime and went for around $825 and Al's are around half that I think.I have both and Al's are better than the Edelbrocks as they were poor castings which I could never keep looking good. swifty
