yeah, I thought the tri-power gto would do even better than it did!
simply because those old Oldsmobile muscle cars are a bunch heavier than you might think!
I know I tuned and modified many of the 1964-67 and 68-70 GTO.s to run really well back in those days!
the guy down the block at the time was an olds guy and we constantly traded tips and worked on each others cars, and he always bitched ,
that there was a ton more chevy, pontiac and mopar and ford performance parts available
