    I am wondering what most guys are using for 10k plus rpm with a screw blown hemi.

    I have been having issues breaking intake springs with duals. I have run the PSI 142X, Manley 1461, and PAC 1361's

    I am a few fast screw blown guys telling me they are having better luck with triple springs. I always thought the dual was suppose to be better for high RPM.

    I am running a 2.520 intake valve it weighs 122g.

    Contact Ken at unlimited Motorsports. He has a custom spring that he sells to every top team . I use them and put 30-40 runs on them. Tell him Jason Kalso said to call. 10,000 and shift and almost 10 in the lights. Don't hammer seats or have tiny little hammer marks on camshaft.
