you need like -5 overlap or underlap to pass emissions.

Sounds like you're looking at a shelf cam from COMP, with only 520/527 lift. But you could gain a noticeable bit more power and torque if you custom order the same duration and LSA, but from the higher-lift lobes. That won't affect emissions, and your lift goes to 558/563.

The Tr224 has passed smog tests before with -4 overlap, that cam has -13 overlap and is way too tiny to justify the swap costs. Go with at least a tr220 or 220r to be safe in passing emissions but even that is still small. I would get a cam spec'd by PatG on EPS lobes for more power under the curve by increasing lift to 0.560-.0570.

I agree with everyone. That cam is way too small to justify doing the swap. a 220r or 224r should be ok.
