I have Promaxx heads with springs for a flat tappet cam, Edelbrock Performer Plus, 224int / 230exh @.050 essentially same numbers as a B303, 5.0 hipo cam but less lift for flat tappet cam. Quite manageable street cam. Flat torque curve to 5500 rpm.<br><div id="yui_3_16_0_ym19_1_1511218316555_4738"> I use Shell Rotatella 30w oil which has the additives taken out of catalytic converter engine oil.<br></div></div></body></html>
