Anyway, good ET all things considered!
using a 240 piston on a 300 crank with a 6.209 rod and a flat top gives it 7.5-1..depending on cc of head, i have not had them cc yet, but they do have 1.94 or 2.02 intake valves, g-pa ported the head years ago, i just bought some 351w pistons with a 5 cc dome, that will put it between 11.5--12 to 1
