Well if the number 7N227311 holds up then its a Yenko (go figure) she's on the 107 nhra list between two others that are also on the yenko list of 54, but we been wire brushing so long we guessed the last number off what we cleaned up all the others are clearly legible the last has a straight part to but could be 5 or 9 can't get top and bottom clean yet to see where and if she bends, could end up both lists if it changes from a 1, We're gonna have to pull the heater box to get a good look at the number- almost there
