timing which, to me was like hobbling a race horse!
And, I think that Buick had 10.5 to 1 compression
ratio. Some muscle cars had an even higher
How could these cars even run today?
I also owned a 409 Chevy and a Pontiac GTO. These
also needed very high octane gasoline.
When I had the Riviera, I tried gas octane
boosters. They seemed to have little effect and
made the engine run hotter.
