Thanks for sharing.
I really like that cam.
I have the Mopar purple shaft duration @ .50 is 238 and has int .474/ext .474 installed in my 273 ,4-speed, 3.55 gears, eddy 500 cfm, hooker headers, and I believe I lost some low end torque. But mid range seemed to pick up a little from the former cam Elgin .420 intake (can't remember the rest) but my stock truck sounded better than my cuda!
Thinking of installing a different cam but not sure yet. I don't burn rubber much and never take it to the drag race and no street racing (yet)
Thinking finding a 360 and stroking it but I'm not rolling in the money right now.
