Re: L31 crate engine issues

Have you done a compression check? It may have a valve over adjusted. Did you adjust the valves? It is rally easy to test the ignition to see if the plug is firing and the wire is good. Shove a plug in the wire and ground it to the engine ans have some one spin the motor over. Did you put the correct melonized gear on the distributors you are swapping in?
