    Finally finished the installation of the new setup as well as air filters and a custom exhaust I fabbed up which eliminates the front fender exits.

    Update. Ended up buying 2 72mm turbos with .68 turbine housings, Single Walbro fuel pump with a fuel pump relay kit, New msd ignition coil and GM roller rockers. Had it dyno tuned finally and since last Wednesday was very hot and humid managed to squeeze out 560 rwhp. Its obvious my cam needs to go bigger since the power starts dropping off around 6100 rpm. The cam I am using has a range of 2000 to 6000 rpms. I guess a call to a few cam companies will be necessary. I am reaching for 650 rwhp. Hopefully.

    I got my cam from comp, call them direct, and ask for a turbo grind cam, I'm pretty sure it was really fair on the price, like $300. Or call lil John motorsports..

    I called them Saturday and spoke to Rob. He sent me a nice spec sheet on a much better cam and its only about 360.00. Said my current cam is leaving a lot of power off the table due to the duration separation.
