Owner: Jim Stuart
City: Montgomery Village, MD
Model: 1973 MGB-GT

Engine Mods: 0.060" over bore (to 308cid), 9.8:1 compression, built by D&D. Big valves & lots of head work.
Ignition: stock Delco dizzy with Pertronics conversion.
Intake/Carb: 500 CFM Edelbrock.
Cam: 50232 Crower, lumpy.
Cooling: oversize aluminum radiator made possible by cutting & boxing frame per Mikel Moor's example. ("I used 16ga galvanized to make a "C" channel which lined the frame cuts & became a bottom channel for the rad to sit in.")
Exhaust: custom dual exhaust (exiting on either side of centered gas tank), Rv8 style headers, 1 5/8" tubes.
Transmission: Borg-Warner T-5, 0.063:1 5th gear.

Wheels/Tires: Datsun 280 Z Turbo 15" x 6.5" wheels. Yokohama tires: 195/65/15 (front), 215/60/15 (rear). Rear wheel arches radiused to clear without using flares. ("I took my trusty Sawzall and cut the arches round instead of flat topped. This allowed larger tires to clear without flares, and for the front & rear wheel openings to match like on the '73-'74 round wheel arch Midgets.")
Electrical: Autometer Ultralite gauges including electric speedo, air/fuel meter. LED third brake lamp.
Body & interior: bumpers & side trim removed, Sebring rear valance, ST front spoiler. Miata seats, custom dash made by stripping a 1977 dash, figured Anigre veneer over bending-plywood commercially spray-glued to metal dash. Air conditioning.
Comments: after completing the conversion, an oil cooler was added as oil temps were approaching 240 degrees. Cooler dropped oil temp to 200-210 degrees.
Completed: 2003.
