I’m working on some research into the cost of engine upgrades back in the 60’s, specifically within the hot rod and muscle car crowd of that time. Does anyone by chance know how much Ollie Morris’s Cam-A-Go would have cost? I know that one is rather rare. What about the cost to put a 6-71 or 8-71 blower on a Chevy or a Ford? I’m interested in any info people can share that is accurate for prices of various aftermarket engine upgrades in the 60’s, especially mid to late 60’s.
