I like hearing that. I have a set of lightly used ProMaxx 171's set aside, which supposedly go [email protected]. Those CNC 185 Shockers are advertised to go [email protected]. The TF "should" outpace the Shockers. Do you happen to have any more detail on the street motor, particularly the cam?
Edit to add... Looks like they dropped the price on the ProMaxx about $300 a set too
Cam is a Howard’s... I will try get more details on the build. My friend has built and dyno Tested three 408s this year with the shockers...two of them went to 520-530hp range and the race one pulled around 630hp (11:1 with 680 lift solid roller)
