    no offense, but that seems like a lot of work to still be under 400 hp.

    i'm definitly over 400 now... and it's no more work than i would have had done anyway... engine had to come out either way... new LS1 was $5,200.00... new LS6 was $4,500 or 4,200... i forget... swap engine out... change oil pan over (ls6 oil pan don't work on fbods)... swap pullies over and wha-la!!!

    either way... it's going to be expensive...
    something tells me this is more reliable and economic though...

    which one? a stock crate would be more economic as far as i can see... but not as reliable... a forged block will always be more reliable...

    edited my post-seems like building up an ls1 with forged stuff is just as expensive and more reliable

    Patriot Stage 2's = $1300 (stage 3's have larger valves that don't work well with a stock cube LS1)
    Do not stroke your LS1. Wrist pins create an issue with the 383 LS1. There is a reason you don't see many of them.
    Forged parts (polished stock crank) and assembly - $2200
    42# injectors - $300
    LS6 intake - $300 used

    if you're willing to spend some bucks... look at some of the texas speed crates... i personally want the 408 stroker... i want a short block, and match my own heads/intake to it cant beat that kinda power.... build a engine for under 7 grand through them, direct bolt in, works with stock ecu for just plugging it in... and will get you over 500 to the wheels veryyyy reliably

    For cost and simplicity I would lean towards a stroked LQ9, maybe a LS2, but still retain the LS1 top.

    In fact my plan if no other major failures happen and I get the a 9" in is to put together a 408 and then use my heads, intake, and maybe even cam until a future date when I get the chance to throw some more money at the car. With a forged bottom end I am going to have peace of mind and it is not going to be that much worse then buying a crate motor.

    GM definitely designs longevity into their engines....the Gen 1 smallblock is over 50 years old and still a worthy competitor!

    A link Wesman gave me. CrateEngineDepot "service" Ls6 engine.
    http://www.crateenginedepot.com/stor...-P1625C63.aspx

    Same motor, same 405 crank hp, just bolt on all your accessories, intake, manifold/headers, etc. I dunno, it seems like a damn good deal...
