Banzai Buford
This portly (nearly 4,000 pounds with driver) '72 Buick Gran Sport, owned by Tom and Debbie Jenkins of Champaign, Illinois, has run a best of 11.17 at 121 mph. That much heft requires some serious grunt to move with alacrity. Tom's Buford gets its motivation from a 0.040-over 455 sporting Bill Miller 11.7:1 forged slugs, a lumpy Lunati flat-tappet cam, and fully tweaked iron heads off a '68 430. A TA Performance intake and King Demon carb are perched on top while Kenne Bell headers handle the exhaust. Tom normally runs his GS on a mix of VP race gas and pump premium. Last winter Tom made some changes and is hoping for a high 10 on the motor before he whacks it with laughing gas.

Street Super Stocker
Chrysler never built a '69 Hemi 'Cuda, but the handful of '68 Hemi 'Cudas and Darts have left an indelible mark on Super Stock drag racing for more than 30 years. Knowing these lightweight A-bodies mix well with the hemispherical wonder motors, Tom Hunsaker set out to build his own '69 version-the one Chrysler never built. Hailing from Springboro, Ohio, Tom felt that if he was going to shoehorn a Hemi into his diminutive Barracuda, he might as well make it one with some serious cubic inches. So, he screwed together a 528-inch thumper utilizing a Mopar Performance "Mega Block" as a foundation to house the 4.15-inch stroker crank, and MP 12.5:1 pistons. The aluminum MP heads were then treated to a home porting job and converted to a dual spark-plug configuration by Indy Cylinder Heads. Tom also procured a magnesium cross-ram for that nostalgic look along with a pair of 770-cfm Holley carbs and an NOS Pro Fogger for "insurance."
