Too bad the Pontiac Hemis never even came close to put into production. Would have been one hell of a combo in the GTO range
The Ford 429 Boss was a good effort but the Mustangs needed major body and suspension mods to accomodate them. By the time it was sorted the Mopar Hemis were already banned from Nascar simply because they were way too fast.
By the end of 1971 all production Hemis were history.
