1966 Chevy Biscayne
Purists take note: You’ve officially been given the middle finger. With just 22,000 original miles on the ticker, Pat Spangenberg’s ’66 Biscayne is a rare machine made even rarer by the fact that it’s an original L72 four-speed car. The big white beast is flawless from every angle. That’s because in lieu of the factory 427 is a 615ci monster of a Rat that scoots the 4,420-pound grannymobile down the track in 8.77 seconds at 156 mph. As is customary in this group, the B-body gets the job done on 10.5-inch wide slicks and a stock suspension. Oh yeah, that’s with mufflers and a full interior, too. In some respects, Pat is the nucleus of this tightly knit group of street racing throwbacks. He owns Rod & Competition Specialties in Butler, Wisconsin, and although the cars in this group were built mostly by their respective owners, Pat’s done some chassis or heavy-duty fab work on just about all of them. During our visit, he was putting the finishing touches on a ProCharged 2,000hp ’Cuda and a blown and Lenco-shifted street rod. You don’t earn business like that unless you’re as nutty as the clients that commission these projects, and Pat’s Biscayne is proof that he’s one seriously unbalanced dude.
The 615ci ogre under the hood uses a Dart tall-deck block as its foundation and has been fitted with a Callies crank, Oliver rods, JE 12.5:1 pistons, and a big solid-roller cam. Cavernous 410cc Dart Big M heads and intake manifold topped by a Carb Shop 1,150-cfm Dominator provide the air and fuel supply, and the NOS fogger nozzles add an extra 400 hp. For extra security, there’s another 250 hp on top of that through the nitrous plate, but Pat doesn’t have to use it very often. A TH400 trans does the shifting and channels the power back to a 12-bolt rearend fortified with Strange 35-spline axles and 4.11:1 gears.
Biscaynes—in their stripped down, two-door post glory—have always been sleepers. But Pat’s ride takes things to a whole different level. Not only is the ’cage tucked tightly into the body pillars and headliners, it has been painted red to blend in with the interior. The stock bench seat, carpet, and dash still remain. Detach the ’chute, and the only giveaways that something sinister is going on are the five-point harnesses and Auto Meter tach. So if you ever see an unassuming white Biscayne roaming the streets of Wisconsin, you better put your money on it.
