Ive attempted searching, but couldnt locate anything..... What kind of parts interchange is there on a Plymouth Poly "A" 301?? Will any 318 intakes fit this?? Is there any speed equipment for them?? etc etc...
Many of the A series plymouh parts interchange on your 301. while piston size and crankshafts may be particular to your engine things like camshafts, intakes, exhaust manifolds, dissy's water pumps oil pumps etc are all the same. If my memory is correct a 277 and a 301 share the same crank/stroke? There is a 303 size engine floating around and I cannot remember what was different on that one in comparison to the 301 yet the same external stuff all fits along with the basic internals. Weiand #7503 used to be the common and most available 4 barrel manifold however they are not being made anymore and second hand s the normal way to go on these. The later LA engine dissy fits and allows electronic ignition set up The blocks are all phyiscially the same ,timing gears are the same as a LA engine, valves are the same within the A series so it does not matter if you get 318 stuff and put it in as it all comes from the same "family". Some guys make headers for them and the 61 - 71 Dodge Truck boys have some stuff that they make to meet their demands of the POLY engine
