N-I-C-E clip, Mike. The Buick needed a "few more" cubes to STOP the HEMIS" top end charge, otherwise a good match F.A.S.T style.
Dave is Mopar "icon" in the New England/New York "Capital" Region. I remember his recent 'bouts against a Boss 429 Mustang. Both are running in the nines, battling it out now!

The quick Mustang running in F.A.S.T isn't a Boss 429 engine.

It's a very big Cobra Jet or something, built by one of the top engine shops around, BES. I could be wrong, but I think it's around 100ci bigger tham the Roadrunner's HEMI, with a few suspension tricks that I've heard were a tad questionable.

Good running car though.
