I'm sure your customer will or already is very happy with the results. Sounds like it will make a very nice cruiser with some extra power on tap.

A set of dyno headers would have helped power significantly but this build was about originality everywhere except a dependable, modern cam/valvetrain. Wanted the idle tone to sound stock and power curve had to be broad with the three speed. I was awful tempted to put a 3.25 crank in it. Would have been 311 Cubic inches instead of 287

and would be even more amazed of the power output from that "287"......

Power potential is limited by the stock components and CID. The .030 overbore, roller cam and a slight compression bump are the only changes internally. Externally it is 100% correct except the 1958 high HP aluminum valve covers. Very happy with the results. Thought it would be a good post for those interested in retaining a totally original sound, look and numbers but want a little more out of it, more of a "corvette" performer. I am a firm believer in roller cams, even used the stock timing cover and rebuilt damper. Since this is a low mile, correct car other than the engine was shooting for a return to original configuration. The 340 HP 327 in it now has a tripower on it. That was the big thing in 1962.
