I was thinking about the 231/236-644/614 from TSP, it's very close to the t-3 cam they have for the LS1. Not only power, but driveability and sound are concerns...any imput would be helpful, thanks!

 

In our auto LS3 I'm using CompCam 231 239 .617" .624" 113.

 

Any vids of the Monaro?

 

If drivability is a concern, our LS3 Street Heat Stage 1 camshaft would be a great choice. In the vehicles it's been installed in we've seen 48-52 kpa at idle. For example the stock cam pulls within 2-4 kpa of our Stage 1 cam. This gives great driving manners as vacuum is literally unaffected.

If you're looking for a cam that gives instant response off idle and gains across the board I'd highly recommend it.

Specs are 227/238 .614/.585 115+5.
