Treesavoy,
Its guys like you that run it out the door all the time when its not nessisary and don't think about what NHRA/IHRA will do to the HP rating. Its guys like you that made the 300hp combo in super stock impossible to run anymore. Thank god guys are getting smart and are running 400 combo's and low HP 350 combo's because the 300hp combo would be re reated to 400hp by now. Pretty imbarrasing getting spanked in class by a 305 or a low hp 350. The 400 is the worst of them all. They are 410 inches by the time they are .070 over and have almost 12.0:1 compression because someone who does the blueprinting for NHRA doesnt know the proper chamber size of a 400 chevy.
