340 Cam Change - Lunati vs. Comp.

Thank you to everyone for their opinions. I'm glad I have heard from people who have actually had these cams in their car.

My next question is regarding the heads. Will I be ok with simply changing the springs and still using stock rockers, push rods etc.???

The car ran 14 flat @ 99mph the few times I ran it. It currently has stock 340 intake with a 850 thermoquad. It has 3:91 gears and weighs about 3200lbs. Any ideas what it might run?

Thanks for all the help...this is fantastic!!
