Mine is the LM7 iron block, so that makes me feel somewhat better about running boost with the stock parts.

If its any help my little 4.8 has seen repeated 11-12#'s on a less than optimal tune.With no signs of damage ie plugs look good no smoke just a little head liftage.

I think the latest dyno graphs are posted on my CD page, click my sig pic.

Stock heads (never been off) intake is Volant.I'm running 21* with no KR. Meth yes. Powerband is from pedal down to pedal up.

Oh, just checked the graphs, it was 530 blower onlly

What kind of plugs are you running? What kind of timing without the meth?

Whats up with the big dip in the dyno chart around 3200rpm?
