I have a 1954 Dodge Coronet, and need info on the motor. It is a 230cid 3.8 straight six, and need to know the compression, bore, stroke, pretty much all of the measurements of the motor. I cant find crap online, so was hoping someone knew of a place that has all of the info i need.

ndoerr,
As MR says, the 217.8 (we call it "218 Dodge") was the common engine in that era of Dodge. The 230 was available in many models, but have no specific data. The bore for 230 is the same, 3.25". The stroke is a monsterous 4.625"! Based on the length of the stroke, that engine would make a bunch of low-end torque. Probably more used in trucks than anything else. (just a suggestion, not a known fact)
Parts for 218 are still readily available. We did one a couple years ago for a '54 Plymouth Plaza. All the rings, bearings and gaskets for 230 are the same. The valve train is also the same. The piston and/or connecting rod would be different, as would the crankshaft.
FWIW

Yes, they were very popular in Dodge trucks and were also used for many industrial applications.
This engine and it's larger brother were a 1930's design but were used in cars and trucks up to 1960, when the more familiar 170-225 cid "slant six" took over. I think they were manufactured for industrial use for some years after that.
Funny story......... during WWII, the Allies supplied the Soviets with many items, including Dodge trucks. After the war, the Soviets manufactured copies of these Dodge trucks for their own use.
After Castro's revolution, in Cuba, as we know, Cuba received all kinds of soviet military equipment and supplies; including soviet copies of Dodge trucks.
As we know, Cuba is chock-full of 30-'s to 50's American cars for which the Cubans cannot get parts.
6 cyl Plymouth and Dodge cars were favouries for Cubans because many car driveline parts could be stolen from military trucks or bought (bribed) from soldiers.
The Soviets copied the Dodge design so perfectly, the Soviet parts would work well in the American made cars.
