Chevrolet C10 6.5 V8 Hydra-Matic from 1969.
The car is privately imported.
Custom built show car on short chassis. Totally renovated for approx. 75,000 dollars. EFI iron block, H-beam stakes, Holley Hi-rise with injection, 102mm throttle body, 3500 stall converter, Turbo 400 box, March pulley.
The frame is Z-welded for a lower look with maintained ground clearance. Short flatbed from a 94 SWB. Power steering and electric lifts. Boyd Coddington rims and Billet steering wheel.
New engine system and mapping in 2023. Estimated power approx. 550-600 hp.
When measuring power and mapping, the car was equipped with a so-called High Speed stall converter without electronic lockout, then the measured values will be incorrect.
This is because torque at lower rpm is multiplied in the torque converter and you cannot get a 1:1 ratio between engine and rear axle. Compensations for this are difficult to estimate and in this case they looked at the logging that was carried out, as well as what the power curve looks like.
The mounted torque converter is best suited to drag racing where ET and top speed matter.
These figures should therefore only be seen as a measuring stick between the runs made during calibration and not be seen as a definitive value. It's hard to estimate the output, but it's definitely more than the 367 measured horsepower. There is a scratch that gave 398hp at the wheels, but then the car was throttled.
