the latest in Pontiac performance.
1976 Pontiac Trans Am with 455 testing out the new engine
In car video of a 1976 Pontiac Trans Am with a 455 in it. This has one of
the comp cams extreme 276 cams in it. Probably the most potent cam I have
used in any of my pontiac engines and still maintained excellent street
manners. Unfortunately, one of the rod bearings did not hold up as well.
The purpose of these runs was to try to get the car to blow up if it was
going to. It has a slight noise in it that I couldn't figure out. Wound up
being top rod bearing on number 7. Was torn down never to be assembled
again. Car was awesome though. Sold to Volo auto sales in Chicago. They
painted it and sold it as a 50th anniversary clone car for $20k more than
they paid me for it.
