I need a spring recommendation for some GN1 heads. The cam is a DLS 218/218 hydraulic roller with morrell lifters and T&D rockers. The cam has .545 lift on the intake and .512 lift on the exhaust. I am not sure what springs Dan used but the engine doesn't seem to want to RPM like I thought it should. It won't pull past 5500. I had a solid roller a while back that would pull 6500 all day long. I have yet to pull a spring and check the pressure but I will as soon as I can. Whenever I make a pull the motor goes to about 5300-5500 rpm and stays there as the car accelerates. Not sure what the max rpm is on this cam but i figured it would be more than 5500 Thanks.
