manley ss valves 11872 11873 I opened up the plugs to .050. My old motor liked it that way. Driving around at low rpm it feels like it is loading up, of kinda huffy, like it's puffin. When I get on it and it goes to 4500, all that quits and it comes on like a screeming banshee, and breaks the tires in second, by the time I go through the gears I'm scared to death. Now I see why owners upgrade the brakes. The msd wires are kinda sloppy on the plugs? I have my timing control all the way advanced, and bringing down don't help. My old motor used the same dizzy MSD 8577 and it did not do this. This motor did not do it yesterday. Is this a symtom? Thanks Bill
