Howd you start likeing mopar?
My dad raced a 63 Max Wedge called the Wailer around Detroit in the 60's. His last car was a 70 duster Pro stock. I watchd as chevy's and fords would break and we just ran and ran and ran. The only tear down each week was to check the bearings. Mopars just seem to hold together. I believe its because the crank is not hung, but up in the block.
