In back-to-back testing with the KC 195 S heads against
the AFR 185 and Edelbrock Performer cnc heads, we have seen
an increase of 20ft/lbs torque and 25hp.
We then tested the KC 210 S heads against the AFR 205 and
Edelbrock Victor Jr. heads; we have seen an increase of
15ft/lbs torque and 20hp.
These tests were performed on a pump gas 408ci engine with
a hydraulic roller camshaft. We believe the power gains
would be even more significant with a high compression,
solid roller engine. |
