When going over Chris' build with him, he told me that he wanted a milder build: something with horsepower/torque where he would be driving the car the most, and something able to run on low/mid octane pump gas if necessary.
Compression ratio is right at 10:1.
The camshaft is a custom Comp Cams billet steel hydraulic roller, 243/249 @ .050" using individually picked Thumpr lobes. These lobes are quieter than the Xtreme Energy and XFI lobes and seem to do very well with the FE setups. Lift is .610" on the intake side and almost .590" on the exhaust side. Lobe centers are 110° apart, with the ICL being on a 104°. The advanced intake lobe centerline offers really nice throttle response and low rpm manners.

Brent - What do you estimate the HP and torque and at what RPMs? That looks like a really sweet street build.
