BTW- the cam is 228/234-114 .588/.574", it idles like a ***** cat and drives as nice as a stocker.
Boy, those new wheels sure do look nice on my car......

We found someone willing to let us use his car as a guinea pig and I went to work using a new cam grind and doing up a trick set of 5.3 heads with some unique port work learned from our Super Stock LS1 engine development. They come in at a paltry 195cc's. It requires modification to the manifold as well and the customer already had a FAST intake and 90mm TB so I matched it to the new port design. The car has a stock flywheel and clutch, heavy wheels and a 12 bolt to boot. I think it will run even better with a 1-3/4 to 1-7/8" step header as well. We just put an underdrive damper on it so we will post more results as they are available.

The graph is SAE
The rest of the info is in my post # 11
I just right clicked on the graph that I scaned and copy and pasted it into paint, then saved it as a jpeg. That is how it came out
Maybe someone from HiTech came post it up correctly.
