Any low 11’s 6 - Pack cars on here ??

When I first had a stroker motor built with a 6 pack, I wanted to see if how the same motor ran with a big 4bbl on the dyno. The results were interesting. Valve train instability(which is evident on the dyno charts) almost cost me the motor, and led me to switch over to a street friendly 10.2 to 1 compression, a custom valvetrain set-up by B3 Racing and I went to a solid roller picked by Dwayne Porter, who found the root of my problem and helped figure a way out of it. The car runs below the 11's, but the information is still interesting.
