    a HUGE thanks goes out to Wickedspeed Motorsports, for doing the job and doing the job so well! :happy:

    here's a few responses to questions people have asked on other forums:

    hows it run? how do you think it runs?? it runs strong.:read: from the line, it'll just roast the tires...rolling 30, it'll light em up as well, but it loves the 30-80 run :head2: ...rolling 60, it'll bounce up to 90 with a quickness.

    The intake? that's the first of wickspeed's new intakes...i really like the way it looks, what do you think?

    The exhaust? sounds amazing. not over powering at 2k and under...sounds real nice at 3k-4k...and sounds evil as hell anywhere above that. from 3.5k and down or so, you can almost mistake it for a regular truck with a nice exhaust...anywhere above that and they know something is a little off under my hood

    Cost? well all the parts, including a few items that i didn't use, around 6k. as far as the labor goes...i got a great deal, so i'm not going to go into it, so don't ask

    Few people have commented saying "it looks factory"...i love that! that was the idea from day one and wickedspeed pulled it off nicely:head:

    As far as burnout pics and vids? soon...my friend's pos computer blows. i'll post em as soon as i can.

    the intake is a new one that wickedspeed motorsports is starting to get made...i got the first. you can email Sky Pattavina at sky@wickedspeed.com

    The headers are actually summit shorties (pacesetters without the cool stick )

    The radiator is the stock V6 one...it's the same size as the 4.8/5.3 one. and the fan are stock LS1 fans out of an F-body

    I'm doing the same swap . What did you do with the evap line ? I was planning on using my old return line as the new evap line after modding .

    my first post - whassup folks!

    thanks J, glad u like your new setup! get the trans squared away and let's finish dialing in the tuning...

    the intake is my new MFI setup, Onyx got the prototype. email me for more info, (sorry to those that already emailed me, try me again! ) I should also have some info and pics and such up on my website soon, www.wickedspeed.com

    as for the evap line, sorry man its gone, hehe... none of the emissions pieces made the swap, and I deleted them all from the ecm during tuning. we just fabbed a small plate to cover the port on the header.

    any other questions on the swap, please feel free to ask!!!
