Every camshaft I have put in the past 35 yrs have been degreed.
And yes....i got the same results back then and I have two MP 590 cams in use now.....one is a 360 and one in a 408
Sounds like you have a fair amount of experience with purple cams - I dont.
I am thinking of using 528 cam on a new combination
Street only application, 3100lb A Body
Lock up 727, 3000 stall, 3:55 gearing, 28 inch tire
.030 over 340 LA, mild ported X heads, 10.5 static, gasket matched dual plane, Edelbrock 800 cfm, TTI step headers.
Looking for the cam to promote low - mid range torque with good street manners.
Opinions valued.
Thanks

Edit tire size
