I had three Stromberg 97s on a 261 in a 1951 Chevy back in the late fifties-early sixties. I recall that I needed to tap on the sheetmetal firewall brace slightly to gain adequate clearance. The mod was barely noticeable.

Drew is correct about boring the 235. Most people felt that 3/32" over was the max safe amount. That would give 248 cubic inches with the stock stroke.
