Ya the ink was kinda weak, and it didnt scan too well.
Bret Bauer custom spec 236/262 @ .050, 110LSA, .6xx/.624" he did not want me sharing intake lift, call him and get him to cut you 1.
we puled it up to 7800 on 1 pull, but it fell off hard after 7700.

No cam bolts? Cannot remember, pretty crazy, never thought a all motor cathedral would mind that rpm without serious springs, ect.

Holy Cow! 7500 RPM!

That thing is making serious power. You might make 1 low 10 second passes before they show you the door.

You needed a rollbar before....now a cage

Guesstimate 10.16 @ 135 in decent air,with perfect launch/shifts.

Now get it in the Camaro so we can hear her

thanks for the congrats guys
.050" cut from heads, .040" 4" bore cometic gaskets to get it to 11:1
- no real porting, I just smoothed out a couple rough spots, kinda made it look pretty, probably acounts for a bunch of mental hp, but no real hp, lol. I did remove the injector bosses from the ports of the intake manifold runners, they are fairly big. Port alignment was good did not need to mess with it.
I'm Lovin theese little motors

Wow man! Impressive results. Have you done or considered the trunion upgrade on the rockers?

You are going to be spinning that thing with that power curve. I would hate to hear about an engine failure due to a rocker eating itself.

I know they are tall, but I bet that motor would pic up significantly with a Mast or All Pro intake.

this entire engine setup is as low buck as possible

Those intakes are crazy expensive and they are tunnel ram tall.

Do you have good axles and drive shaft loop?
