490rwhp NA LS1, with a baby 227 cam

Interesting thread by Tony Mamo from AFR on this build.

The impressive part is that it only uses a 227/231 cam, granted with 11.6 CR, but is still fine on high octane 93 octane fuel

Looks a good solid NA build, with phenomenal figures. Just a couple of questions:
1) how much lift? What ratio are 10mm rockers (never heard of rockers referenced to like this)
2) is that US hp, so around 445rwhp in the UK?

Either way, impressive results

Only a bit bigger on the intake than your cam mikeyb1987

True James. It must mean I should be able to screw some more power out of my setup!

I think there is more power in your cam as iam on 419rwhp

We need to organise a rolling road day, so we can compare

I'm 90% convinced to up the Rev limit and see what it'll do beyond 6,600rpm.

Using an arbitrary, but not ungenerous 20% drivetrain loss.

That chart yields a maximum BMEP of 217.04 psi at 4750 rpm - Looks a bit dodgy, like some dyno results TVR / Al Melling banded about some years back.

Don't think Tony Mamo is with AFR anymore. Be careful on Mamo's website (mamomotorsports.com ?). I think it's compromised.

Get your stroker running on the tarmac and I also will be greatly impressed.
