Here is one of my friend’s James Hrovat old videos from Byron Dragway where Brian Hicks ran 7.10 seconds at 149mph quarter mile pass with his outrageous 1974 Dodge Challenger. The menacing Mopar was powered by a twin turbo 526 cubic inch HEMI V8 engine at the time with its best ET being 6.68 seconds. As far as I know, Brian switched to a different set up aiming for more power, but couldn’t find any info on that.
Check out the video to see the Twin Turbo HEMI Challenger flying down the track!
