Lunati 60406 vs PurpleShaft P4452761

I dont know what motor you have but i have that purple cam in my 340 and it is a dog down low and not a lot better up top I plan on replacing it the next time the motor is out of the car.
I see your from West MI ever take your car to Martin?

Yes, I try to get to Martin 5 or 6 times a year. I live in Lowell, MI now.

My engine is a 1970 340 out of a 70' Cuda. High compression.
