PONTIAC - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO

WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY 405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS who taught me most of what I know, often told me Chevy rated their horsepower in a more optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac rated/tested their engines in a 100 degree room, compared to Chevy in a 60 degree room. These Dyno results seem to reflect that some of what I heard was true. Both of these engines are great, but the results do seem to show that Pontiac was not rating their horsepower worrying if it would cause "songs to be written" about their engines .... like the great song "She's real fine my 409"--(Chevy).

PONTIAC Grand Prix (1970 455cid w/rare 4speed, of which only around 500 were made)
A truly overlooked Luxury Performer. One of the top car magazines back in the day tested a 390hp1969 H.O.428cid Grand Prix and reported times of 0-60 in 5.5 and a 13.8 quarter. This 1970 455v8 Grand Prix in the video was rated with 20hp less (370hp for the 1970 455) due to emissions detuning for 1970. The 1970 455 was basically a larger (stroked) 428 with some emissions detuning.

Extended Interview Podcast: http://www.v8radio.com This week, we have a special episode of Muscle Car Of The Week featuring an exclusive interview with Stan Antlocer, former owner / driver of the 1963 Stan Long Pontiac Super Duty Tempest. This car was known in Super Stock A/FX racing as the "World's Fastest Tempest" and was a record holder. It is one of the 6 lightweight factory built cars made. Today, the car is completely restored, and we reunited Antlocer with the 421-powered monster after he last saw it back in 1964. It is one of the many vintage race cars in the Brothers Collection.
