Chevy Big block engine used to test F1 Prototype Gearbox

When McLaren needed an engine with enough torque to test the gearbox for the F1 prototype they chose the Chevrolet 454 big block.  McLaren felt the 454 would have enough torque to replicate the F1’s eventual production unit.

The McLaren F1 set the record for the world’s fastest production car on March 31, 1998
