I’d heard all the stories about the poor low torque of the 041 cam. I bought my 68 off my friend’s widow......has a 428 Manual with RAIV cam and 850 Holley.
It displayed the low torque at low RPM that is a hallmark of the RAIV. I decided to change the plugs as the car sat for some time after my friend’s death.
I replaced the NGK plugs with my preferred AC Delco plugs.......
Low and behold, I got easier starting, better cold idle and I also got a noticeable increase in low end torque.....the car will carry a higher gear through a corner than it used to. All together better to drive.
I certainly wouldn’t say the RAIV is a bad cam.
