A friend just gave me an old but unused Norris Camshaft No. 366-13 and I can't seem to find any information about it. There is a tag on it that is hard to read but might state:
0.490" lift 0.008" valve lash 10 54 deg BTC EC 80 BBC 1C 74 deg ABC EC 48 ATC I was told that it is a pretty radical race cam that is not suitable for a street car. Not a problem for me as I am planning to do a performance race build on my 2.0 liter Type IV at the end of this race season. Anyone know anything about this cam and/or have any experience with it or something with similar specifications. Thanks, Mike S. |

Some fiddling with a caluculator suggests that is a pretty rowdy camshaft. Intake Duration is 308.00 degrees. Exhaust Duration is 316.00 degrees. Installed Intake Centerline is 100.00 degrees ATDC. Installed Exhaust Centerline is 110.00 degrees BTDC. LSA is 105.0 degrees Overlap is 102.00 degrees. That will require a lot of compression and will require RPM to make power. Nothing wrong with that as long as you are building race engine. |

Nothing wrong with that as long as you are building race engine. So what is "a lot of compression", over 8.5? And if "installed intake centerline" is 100 degrees ATDC, specifically how do I internally time this camshaft using a degree wheel? And what kind/type of solid lifters will work with this cam? And thank you for your knowledgeable reply! And Yes it will go in a race motor, either a 2.0 liter or 1.8 of increased displacement. Must stay below 2.0 liter threshold to run Vintage. |
