Specs & Modifications


The stock MGB body shell is a unibody monocoque made entirely of sheet metal. Although the stock body shell is quite strong and rigid, I felt it was necessary to increase its strength and rigidity since I was planning to widen the structure 11" by cutting it in half and increase the horsepower and torque above 500.

To achieve this, I designed a backbone frame structure from tubing similar to the Lotus Elan's, which would incorporate into the existing monocoque. This would increase the stiffness and provide mounting for the LT1 Chevrolet engine, 6-speed T56 transmission, and C4 Corvette front and rear suspension pieces.

The tunnel consists of double-wall sheet steel welded to the 1" tubing tunnel structure, with 1" urethane foam sandwiched between the walls. This construction provides insulation from exhaust heat and tremendous rigidity to the monocoque. The transmission tunnel is wide enough to accommodate the larger transmission and 2 ½” exhaust pipes without them hanging below the bottom of the car.


New floorboards were fabricated 1 ½” lower to provide a completely flat bottom on the car.
