I can tell you I have rebuilt me my F250 460 engine. I just never have done any Mopar 318 engines. I only got hooked on the 318 when I bought my 1st Dodge Durango with a 318 Magnum in it, and then I saw Gary garage on YouTube race 600 hp 318 for drag racing. I wanting to give Mopar a chance, all I've known is Ford's. I picked up early this year a 1973 318 LA that was used for drag racing also that has concrete in the block, and then I bought the 1987 318 I wanted to build a fun daily driver engine out of it.
