does this mean anything to anyone? if so what and is this going to run well in my 5k....

Well, it looks like a mid-top range cam to me, but whether it works well will depend on the carbs and exhaust setup. Don't expect much low down out of it.

 

Lots on Google to find, the rest is just expensive experience you have to get yourself!

G`day mate, I`m running a cam with almost identical specs to the one you have. It is a mid to high range cam 3000 to 8000rpm. The 4k that I have it in has mild head work, extractors, balanced bottom end, 32/36 dgav weber and 1 3/4 exhaust. It is quicker than your average 4k but very dissapointing in traffic. Its got nothing until 3 grand and then pulls strongly through 7 grand. Not practical for a daily. Of course, it depends on what you want to use your car for, so the cam will either be just right for those weekend things that we all do, or a real pig as a daily. Oh, and its as lumpy as hell too. Great stuff for a while but you may find that you soon get sick of having double vision at traffic lights. Good luck with the build.
