It may not be the most powerful...
It may not be the most powerful big-block out there, but the torquey World Products 540 is the ideal lump for a heavy B-body. The all-aluminum crate motor is 100 pounds lighter than its iron-block counterpart, and tips the scale at a reasonable 595 pounds.
Interestingly, despite his penchant of Chevys, Mike works as a service adviser at a Ford dealership during the day. Yeah, the guys give me crap about that all the time, he admits. Mingling with the Blue Oval faithful does have its benefits, however, and the idea for the Biscayne’s vanity plate that reads GDZILLA came from the most unlikely of sources. I had a customer come in one day with a Lincoln Town Car. She said her car is so big that she calls it Godzilla ... I thought it was really funny and the name stuck with me, Mike says.
Integrating modern technology into older muscle cars has always been part of hot rodding. These days, Pro Touring machines are taking that concept to the extreme, offering levels of handling, braking, and comfort inconceivable just 10 years ago. Nevertheless, even as g-Machines continue increasing their market share, simple straight-line machines have and always will represent a large core of the hobby. As Mike’s B-body Biscayne so resoundingly affirms, basic can be brilliant, and big can be beautiful. So while other fads may come and go, street/strip machines such as this Biscayne aren’t going anywhere.
With 665 lb-ft of torque,...
With 665 lb-ft of torque, 3,700 pounds of heft, and sticky tires, Mike didn’t want to risk rearend failure and went all out with a Dana 60. The dual 3-inch MagnaFlow exhaust system was originally designed for a Chevelle, but Mike adapted it for B-body duty.
