A 100.00 is alot less than I thought it would be a friend of mine took his '63 327 to Buck Kinney cause it wouldn't go thru air care,wants his collector plates.Buck set up the carb and distributer and drove it thru air care for 300.00.When he got it back he couldn't believe the power it makes now.I'll tell him about Mopac he might like to know what kind of new found power its making.I think its amazing what little it takes to make these small blocks go
