Yes new springs. We pulled the engine out of a drag truck that is was running great in. it only had a couple of passess on it at the time. It had an msd set up on it but I was unable to get it with the engine. Do you think I would be better off ordering an msd distributor or maybe a mopar performance one rather than messing with this distributor?
The other question I have is about the compression. I know it has flat top pistons and 516 closed chamber heads. Anyone have an educated figure on the compression? I am not sure how close to the deck the pistons come up to unfortunately.
Thanks Sam
