218 to 230 conversion

[Forrest]

New to flatheads and I've heard rumors the 230 flathead is the same as the 218 but with different internal components. Can someone please elaborate? What parts would be needed to convert a 218 to a 230?  Also are any parts from a 25" 237 spitfire industrial engine compatible with a 23" 218? Thanks.

230 has a longer stroke than the 218. The crankshaft and connecting rods are different. Other than that they are virtually identical.

Not many parts from the 25" engines are compatible with the 23" version.

To convert a 217 (218) to a 230  you need the crankshaft, the rods and the flywheel.   Although the 217 flywheel will fit, there may be problems with the starter ring gear .

Merle is quite correct in that not so many parts from a 25 incher will fit, however these parts will :  Timing cover, chain and gears, fuel pump and oil pump and the water pump

bell housing and possibly the flywheel, and engine mounts.    The distributor on a 25 incher has a longer shaft.

Awesome! Just what I needed to hear. Thanks a bunch.

Hey Kevin,

Not familiar, but I do have a friend down the street with a 1955 dodge he just put on a 4x4 S-10 Chassis.  He'd probably recognize it.  Hope you enjoyed your visit through our small logging town. Thanks for sharing.
