The owner did back to back testing on this tuff Hemi 6 engine. The first manifold used was a Cain Hemi 4 barrel when fitting an Aussiespeed plenum pig a gain of around 20+ horse power was seen. The Centura was then fitted with the AS0298 Aussiespeed manifold and another gain of 10 Horsepower was seen. The results from the customer were around 25 horse power with an increase in torque with the torque curve extended another 1200 rpm at the top. This is a full cast iron mechanical camshaft engine making around 300 horse power. The manifold from cylinder head flange to the outside of the carb pad is 290mm long.
