Randy, the best advice I can offer is to be careful in the LSA or overlap of the cam you choose... (lobe separation angle). With a boosted motor, too small of an angle and you are pushing boost out the tailpipe... If I remember correctly what I've learned... The big rump rump cams have small LSA's and that's where part of the shimmy shimmy shake comes from... They sound old school amazing, but are not the best choice... My cam of choice which would serve you very well for a 66-7 without VVT has a LSA of 121 degrees. My thread has the box end in a picture where you can see the rest of the specs...I listened to a CTSV caddy with the same cam, wicked sounding, very drivable, and making 638 hp with a few other minor goodies...6speed manual trans mixer, but none the less... good luck... And get some suspension going or you leaving HP and rubber on the asphalt..I'll see you in about 4 weeks... If you want to, I'll let you try a set of 18 inch wheels and MT drag radials for a pass... But not in the pass against me... Well, that might make it fair for you...
