How Accurate is Camquest?

It depends how good your heads are.We have a 10.5 comp 360 with UNPORTED EQ Magnum heads ,a good solid cam that is in the upper 230,s for duration,a Performer RPM intake and a HOLLEY 4412 2 BARREL carb that makes 452 for power and 445 for torque.Just because your heads are ported doesn't mean the are done correctly.Furthermore,if it is an automatic with not enough stall and not enough gear it will not seem very quick.
