Hello Ian K and Jimmy M, I have a few friends with GT40's but I work on Roy Sayles demonstrator car and I do some of the engine and trans installs on CAV's that he sells.
The blue car is Roy's and the silver car minus the gearbox is Carl Staubs(now registered on this website).
My engine is a 347 short block(minus cam and lifters) from Ford Racing, it is a Sportsman block(beefed up 5.0 2 main bolt block) with Probe forged pistons, rods and crank.
I assembled the engine myself( I can't call it a build, there was very little machine work on my part). It has all the best stuff, AFR 185 heads, Crower hydraulic roller cam, SVO lifters, Comp Cams rockers and push rods, a belt drive(which I probably won't do again, I have always had little niggling oil leaks and it really limited my water pump choices), Fluid Damper, Mcleod steel flywheel and clutch assembly, IDF webers, Armando pan and an MSD crank fired ignition. ARP studs and hardware everywhere.
The seats are modified Sparco Racing seats and fit the car very well, and that is my personal touch.
Sorry for my late replies but Ramona has been the epicenter for all these fires in San Diego County and I have been very busy!
Dave
