Im currently have my flathead at a friends machine shop and planning in getting the motor rebuilt. I know its a 25in block, and according to the previous owner its the original engine for the car. The numbers have been replaced so there is not telling what the size of the motor is? I took of the head to measure the bore size but was unable to get an accurate measurement. Is there any other way of telling what size motor is is? Im very impatient and want to know whether to keep this motor (if its rebuildable) or purchase a larger 50's mopar flathead six.
Here is what my question is, I saw this post omn the hamb and was wondering if this is really a big issue on these motors and how I can go about mentioning this to the shop..
"That the bad thing about Plymouth/Dodge six cylinder engines is that the oil line from the main gallery is drilled straight through. So as much oil goes to the cam bearings as the mains and rods. The fix is to tap the feed to the cam and install a restriction. Maybe with a 1/16 hole. Then the crank gets what it needs.
