| Post subject: | what can you tell me about these cam specs |
its basically jibberish to me, found an old marine camshaft, looked up the numbers and this is what it told me Durations at .050 lift int 198* ex 203* Cam Lift int .270 ex .276 Lobe centers in 106* ex 112* I don't quite understand these figures, usually people speak in degrees like, "Mine is a 270*" or what ever, are these different numbers at different specs? ha ha, I am confused, would appreciate all help! thanx morgan |

Looks like the '71 and up cam which was used earlier as the marine cam. It's about 244° advertised duration and is ground 3° advanced with 109° lobe separation. Multiply the cam lift by 1.5 to get the gross valve lift. Take away the lash setting from that to get the net valve lift. |
