These 272 cams do not require tuning, but are a little faster and bigger than the stock bump sticks.
Cold start up can rattle as the HKS tuned header and valve overlap work things out when it's rich. It's only a few seconds, so the neighbors don't come out with pitchforks and torches.
Warm idle is a little weedy, a little worse than stock as the intake heats up.
Does anyone have any AVCS tips for minor tweaks?

Note: I've done a lot of engine mods and old school seat of the pants tuning. That's the fun part of building an engine!
Next it goes on the dyno for final tuning results. I'm hoping for an A+ on the test.
