Yes, I just got the stock 261 cam installed in the 235 in my 51 Chevy truck. I got the cam from the 261 I've installed in my 1950 Chevy two-door post sedan. I remember the original 235 in the 53 corvette was stock with a 261 cam so now I'm about to find out what the engine will do, but with two Rochester's instead of three side draft carbs.
