For those considering spending serious cash on rebuilding and perhaps modifying the engines on their C2 and C3 Vettes. There will always be deliberation in terms of modifying for better performance but potentially loosing some lower speed driveability and economy and then needing to change axle ratios and perhaps converters if running an auto transmission.
It is possible with careful selection of components (cylinder heads/camshaft/inlet manifold/carb) to improve performance and retain, even improve economy and driveability.
Now it seems that one can significantly improve performance, retain driveability and improve (perhaps significantly) without switching to complex computer controlled fuel injection by the use of camshafts with 'inverse radius camshaft lobes.
There's a thread just started over on the Corvette Forum relating to Mike Jones Camshafts (https://jonescams.com/products/) and their very specific camshafts and related components with these 'inverse radius cam lobes'.
I'll let you read the post and Leigh's analysis and make up your own minds.

Mike Jones Camshaft Analysis - CorvetteForum - Chevrolet Corvette Forum Discussion
C3 Tech/Performance - Mike Jones Camshaft Analysis - There have been some prettty incredible claims on here by some folks that are running Mike Jones cams. Smooth idle - plenty of power - increased idle vacuum like 19 - vastly increased gas mileage These are not idle claims, I have had some long...
