I have a 1973 mustang 351 cleveland 2V motor. It has a 750 4 barrel with a weiand intake and headers and a HEI distributor. I am replacing my cam. I would take suggestions for a cam/kit. I am looking at the Competition Cams Complete Camshaft Kit Part No. K32-221-3 High EnergyGS=; Camshaft Kit; Hyd Flat Tappet;1500-5500rpm;Adv.Dur. 268 Int./Exh.;V.Lift .494 Int./Exh.;Lobe 110 deg;Incl.Cam;Lifter;V.Sprng/Ret./Lock/Seal;Timing Set; But my heads were rebuilt by the previous owner. I cannot find him to find out what springs he used. Is there anyway to Identify my valve springs? Here are some pics. I need to know if they are good enough to use with a Comp cam like the one in the kit. If so I will just get the cam and lifters. I already have a roller timing chain and sprocket set. And could save the money for the springs and retainers and such. I am open to any suggestions.
