Lunati Cam

I'm going to guess just a change to the intake system will improve performance plenty!
As much as the roaster intake is cool to look at, without serious modifications it doesn't work well.

The 528 is a really good cam. Had cars run 11.50's with it, so it's no slouch.

Thanks Rob.
The duster has the potential to run 11s as the time on the 1/8 indicates.
As far as we are aware the STR is the only one in OZ and has fooled a few people thinking big block, performance wise it is lacking at the upper RPM range.

Currently swapping to the Air Gap and 830. At the same time I'll tighten the lash to your recommendation, run it up on the Dyno and the track see what happens.
