MP 360 short block 1976 360 heads-gasket matched with 1.88 intake 1.6 exhaust valves X-celerator single plane intake 904 with 3500 stall conv 4.10 gears The car weighed 3600 lbs completely stripped and I ran a best 12.71 @106mph That was with the power steering still hooked up. Put that motor in an A-body and put bigger intake valves in it an it would be much quicker. I loved the idle by the way.
