Hey Hudson, sounds like you have a great little motor. Info/tricks for Mopar flatties is hard to come by & even harder to extract out of people so thanks for the goodies on yours. My father dirt raced a 250 Dodge in late 60's that had a skimmed head & zoomies with the biggest carb he bolt on. He always knew when it was time for a set of bearings as he could hear the pistons hit the head at an honest 6000rpm!!!! The rods must have been screaming for a break. At the end of season meeting they decided to try & break it's back with a 225 slant in the shed for next season, broke the gearbox & sold the motor to another driver who got another season out of it!!!!!!!!! Anyway I have a 230 Dodge thats going to get the works for my 37 coupe & I'm interested to learn more.
