John-T-53 Posted May 10, 2012 Report Share Posted May 10, 2012 (edited) I just found out my crank is cracked. My guy magnafluxed it today. The engine is all apart again. I think I had a 230 crank in my little 218 block and didn't know it. It has an 8 hole flywheel flange. I never measured the stroke. I need to look into the rods I have. Anybody know the length of a 230 rod or a 218 rod? They ones I have are casting # 954371 I'd like to make sure somebody didn't put the wrong rods with the 230 crank, if even possible to do. Now looking for a new crank....just when I thought all was well. Edited May 10, 2012 by John-T-53 Quote Link to comment Share on other sites More sharing options...
Jim Shepard Posted May 10, 2012 Report Share Posted May 10, 2012 Holy crap, John! You are on one hell of a trip with that truck... Jim Quote Link to comment Share on other sites More sharing options...
48Dodger Posted May 10, 2012 Report Share Posted May 10, 2012 Hey John, I have two motors sitting out here, possibly three. Maybe Jim, you and I can sort something out. Two are for sure 218's (thou you got surprised by what you have...yikes) and the other I've never checked. 48D Quote Link to comment Share on other sites More sharing options...

Merle Coggins Posted May 10, 2012 Report Share Posted May 10, 2012 My parts book shows con rod P/N's 954376 & 954377 for "D" model trucks, which would be the 230CID, and P/N's 1115901 & 1115902 for "B" and "C" models, with a 218CID engine. Maybe your number was used in a car engine? I don't have any parts books for them. Otherwise just because it has 8 holes in the flywheel flange doesn't automatically make it a 230. My 218 has 8 holes for my Fluid Drive unit. Merle Quote Link to comment Share on other sites More sharing options...
Guest P15-D24 Posted May 10, 2012 Report Share Posted May 10, 2012 Should have rights and lefts. 218 cranks are available pretty easily. I think I have 3-4 sitting in my shed. Problem is the shipping as they need to be crated to prevent damage. Quote Link to comment Share on other sites More sharing options...
Guest P15-D24 Posted May 10, 2012 Report Share Posted May 10, 2012 that way it can be identified. Quote Link to comment Share on other sites More sharing options...
John-T-53 Posted May 10, 2012 Author Report Share Posted May 10, 2012 Holy crap is right. I just can't seem to win no matter how hard I try. A normal person in this case would throw in the towell and buy a Toyota (or something like that). Should I just do that? Turns out the crank is a 218. False alarm. It had multiple cracks all over, details still pending until my machinist gets the full report from our crank guy (Armando). A new 218 crank is $550, ground, polished, including all bearings, and delivery. That's at cost from the supplier in Sacramento (I think it's Motor Warehouse). I'm looking into getting a 230 crank now, though. Quote Link to comment Share on other sites More sharing options...
