Bruce Wilson’s Jaguick ( Buick Powered Jaguar!)

Monday, July 12th, 2010

We always like to see something a little different. Bruce Wilson’s Buick 455 Powered Jaguar is definitely different and exceptionally well done. The Jag was rescued out of Smitty’s Junkyard in Pasadena, MD. The body and interior look pretty much as you see here, surprising with the 200,000+ miles.  Someone had gutted the driveline and left the shell.  The car still has the original leather seats, real wood dash and power windows. Now that’s different for a 9 second racecar!  When Bruce picked it up, they put it on the trailer with a forklift and gave him a weary “good luck”.

The body was shipped of to Clark’s Racing Chassis, to get the cage and Ladder bar rear suspension  put in it.  The front suspension is stock Jag, with custom drag shocks fitted by Bruce.  Peters Sheetmetal fabrication handled the hood mods, and Dave Wilson at Southern Automatics handled the transmission.

Tom and Bubb at Burtonsville Performance Machine were put in charge of machining and assembly. The Engine is a basic 464 CID combination, with a stock crank, 4.350 Bore CP flat top pistons, and TA Performance Stage 1 heads that have been fully ported. The Cam is a custom flat tappet from Scott Brown @ Competition Components.  A Dominator is perched atop a KB Wildcat intake (Now the SPX)  and sealed to the custom hood.

The Jag really hauls the mail, running a best of 9.71@ 137 best with a 1.32 sixty foot time.  Not bad for a 3300lb car running a 3.50 gear. No, we aren’t kidding!  Usually though, Bruce takes some timing out and short shifts to run 10.00 Index races. This past weekend, Bruce was runner up in the naturally aspirated shootout series in Maple Grove, where he is currently the Points Leader.  Congrats Bruce!


Dyno Test: 464 CID Buick with Edelbrock heads on E85

Sunday, October 18th, 2009

The purpose behind this engine was to build a max effort street strip Buick 455 combo, using the new Edelbrock heads. The heads are fully ported and will be available from Competition Components. The car is regularly street driven, weighs 3900+ lbs and is cruised regularly, so race fuel was not an option.
