A Corvair Legend
Salih Engineering is unfortunately no longer in business, but their memory lives on. They were once the manufacturers of a variety of Corvair high-performance equipment, including overbore cylinders, pistons, custom camshafts, and valve lifters & springs. They also performed custom head machining.
Below is a compilation of information on Salih overbore cylinders and pistons, originally found on two pages of their 1 January '73 flyer. Don't the prices want to make you just cry? (Of course, in 1973, the parts cost no small amount of money, and the "add 10% to prices" rubber stamp on the page indicates they had recently upped the ante.)
