although with the MP112 and headers/exhaust I did see a very nice increase in power. stock 240rwhp, MP112/headers/exhaust 430rwhp........so about 190rwhp gain

Aren't there a couple of guys doing the swap or have it done? I would like to see some numbers.

AWSOME!!!!!!!!!!!!!!! where did you get it dose it come with install instructions how much???

So how much will a 4.8 5 spd put down stock? 220-240rwhp maybe?
I put down 445/489 tq with a stock 4.8 short block, stock heads with 9.5:1, 216/224 114 .558/.558 cam, meth injection, & a 3.00" pulley that gave 12lbs boost. It wasn't even a purpose built engine with lower compression etc...
I built at least 200 more rwhp with a cam and meth on 93 octane. Please enlighten me on why you would bet $1000 to prove Brian's statement wrong or I will do it, or even better again and take your $1000.
