I can tell you first hand that trying to save a M130 is basicly cost prohibitive. I wound up with a very nice 65K 1965 250S with a seized motor. I am a bit of a purist and I really wanted to "save" the original motor. I am very resourceful when finding parts but I was shocked at the prices to put the motor back into nice condition. I came up with about $4,000.00 with new pistons, rocker arms, gasket set & machine work so I gave up and put my efforts into an M110 from a 123 Chassis. Parts are considerably cheaper and plentiful. The engine puts out more HP which is a plus and there are articles on the web about Megasquirt fuel injection on this motor which I am very interested in versus carburetion.
