Our goal was to extract as much power as possible from the factory 114″, without lifting the rocker boxes.
We gained 50+ Horsepower vs the factory 114″ and ran multiple 10 second passes throughout a meet at Benaraby Raceway! Pump fuel, stock clutch, foot shift, 17 x 5.5 XR1200 rim with Shinko Hook Up tyre
140hp/137tq STD 138hp/134tq SAE
And finally.. 10.68 @ 120mph 1/4 mile time slip. We’re not sure if this one was STD or SAE correction sorry : )
The rocker boxes have never been removed from this engine – This is a TRUE bolt-in cam that works with the factory valve springs.
