Corvette 235 engines supposedly produced 150 hp (1958 235 engines supposedly produced 145 hp). The Corvette 235 had three side-draft carburetors and a modified lift (261 truck) camshaft. The GMC 302 straight six with Wayne "12 port" head supposedly produced 300+ hp. Here is another interesting article about 235s. | | |
