We have a large number of C3 owners in the club that date from the USA's emission era (so '74 thru '80) - these are typically 'soft-tune' engines with low compression and mild cams. They'll perhaps have 'the show' but not always the 'go' (certainly not enough 'go' for some members!)
There is plenty of information out there on how to 'warm' things up a little but very little information in terms of actual facts and figures relating to the horsepower and torque gains......i.e 'bang for yer buck', so to speak. This thread from the USA's Corvette Forum addresses that issue.
Scott has a '77 L48 which sounds much like many of our CCCUK members Vettes. He is also lucky enough to have a friend with a chassis dyno. Read the changes he has made to his car with dyno results recorded at each step........quite interesting.......and still on basically what is a stock engine (so no cylinder head or camchaft changes........yet)
