I'm doing about the same only with a Tattersfield I've had ratholed for years. It has a pair of rochesters on it. The only color left was a little patch of blue on the underside. It was from a 216. Hope to make it work on a 54 235. What is the scoop on cams for a 235 with 2x1's? I have to go thru this motor any way and if I need to replace the cam I might as well get one that will do a little better than stock. What do you recomend.
