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.

Compression above 10:1 would be preferable. Depending on piston design and race class limits, I would push as high as possible 13-14:1 would be nice. This engine will need race fuel.

Camshaft timing can be adjusted with offset Key ways, bushings in the bolt holes, etc. You will need an aftermarket timing set. Pauter Machine used to make a nice straight cut steel setup. I ran that on my street car when I was 25. HAHA. Its pretty loud.

You will have to assemble and disassemble the motor several times to properly degree the camshaft. Its far from easy, like some other engines.

I would build the biggest engine you can get away with. If 2.0 is the limit build it to 2056.

As for lifters, Web made good lifters, but who knows now. Ceramics would be nice but are unobtanium right now. Talk to L&N engineering about what is working best for them and what they sell currently.
