Colorado Emissions Cam Question

[87ctls]

I posted this on the Camaro site, but apparently there is no one there that has to pass the Colorado test.

Ok. I now know what I have to "Visually" have to pass the test here in CO.

So, a question to the Denver metro guys who have to have the idle/2500/idle test done and have passed without de-tuning the car to death.

Engine size 383 or 400. Car Year 1976 to 1981

What are you running in you car as far as head cam and compression go?

Now this crate ZZ4 is suppose to pass. It has a 208° intake / 221° exhaust cam. Speedpro says 214/224 112 lobe

Anyone run anything bigger that passed?

wish I could help but I had hell trying to passing my target master 350 with the stock cam and a edelbrock 1405 carb.... :? and they lowered the NOX output limits.. I decided to do ls1 swap instead..

Target masters are the really cheap and poorly setup SBCs, a 96/02 truck Vortec crate motor would be a good swap, much cleaner burning heads.
