LSx Compression with Boost?

[RSX302]

Thanks for the pic, now I can't stop drooling.

So mill the heads and you'll be good to go. Keep in mind, although that timing even under boost seems low, if AFRs combustion chambers mimic the factory design it's not that bad. In naturally aspirated form, the factory heads chamber design is so efficient that you'd be hard pressed to find needing much total timing to reach peak power.

The chassis dyno will ultimatly tell what the timing will be. give motor what it wants..right.
