    Dyno'd the new cammed L76/Ls3!

    Well guys I dyno'd my new setup yesterday, its a L76 6.0 with Ls3 heads and a healthy cam. I am very pleased with the numbers. Converter was locked during pulls and cutout was open..

    Here is a dyno vid, graph, and idle clip. Sorry vids were takin with phone so the great quality...

    Track times coming soon

    you running 2.5 dual exhaust? if you are i would stay with it, if not and youre 3" i would make a dyno with the cutout closed, reason i say this i lost with cutouts open on a 3" dual setup so i removed them.

    you have any future plans to push the rwhp up? i bet you could reach closer to 500 pretty easy

    i know what ya mean lol when on the dyno things tend to go blank

    Running a 2.5" ORY into a 3" single muffler with the a single cutout right before the muffler. I want to do a 3" ORY instead.

    Ya I am sure with with some 1 7/8" headers, better exhaust, and some P&P heads I could get pretty close to 500. Dont really have any future plans, Maybe some silly gas if I get tired of this power lol
