Zenish. 305 for a 235. Blasphemy!
BTW. My 261 w/od & 3.31 rear end does about 2K rpm at 65. 18 mpg and running rich. Working on the jets this weekend. Currently have all the wheels off to check the balance and front wheel bearings out and back in for repacking.
Going to Goodguys in KC, MO on the 23rd.
