    Looks ok.

    You might get mid to high 300's CHP, no way you'll ever hit 450 without a turbo.

    Any cam with higher rate valve springs should run a double roller.....I've seen a few single chains and dampener on after market springs....its not pretty. He would be out of his fuking mind to run 130 springs on a single chain. Plus he probably wants the drive ability of the XP

    OP, build looks really good man! With that setup u would b okay to start with about a 3.25 pulley, imo

    A 3.4 setup with an xp cam is good for roughly 300-320 whp... So FFDP is prolly right, u will most likely be high 300's. But I agree with cop, you could start out with a smaller pulley if u are running a cam. But remember to scan.

    Good luck with that l26 bottom end. And it's higher compression as well. He can stay with a 3.4. Hell I would leave to a 3.8 until he goes intercooled then drop the pulley.

    Pretty sure Ive seen many times now its the L26 rod bolts that fail not the actual rods failing. Go buy some ARP ones. I believe there is a thread on GPONA.com about this if its not here somewhere also.

    i feel like you're gonna run your injectors static quick. and the headers will usually replace the downpipe portion of the exhaust, as well as the cat, so keep that in mind when you buy. be ready to put a bigger pulley on that too, the genV is a lot more efficient and you're still on a high compression block. a modular pulley hub makes life easy. other than that, looks like a solid build and i wish you the best of luck
    99 GT - top swapped, S2X cam. - sadly, sold
    96 Firebird Formula - T-tops and exhaust leak. 14.26 @ 97.8 - sold
    2008 Chevrolet Cobalt SS - stock, in all of it's turbocharged awesomeness

    L26's throw rods sometimes, but this is primarily with Turbo or xpz 6600 ron shift point builds. Nothing to worry about with your goals.

    An XP/s1x setup on a 3.4 is not gonna make 320whp. You might get near 300, but even with high compression and a Gen V, I doubt it.

    Ditch the double roller and the 130# springs. Get cheap 90# springs. They will make more power, and wont tear sh1t up in your valvetrain. Ls6 springs can take you to 6500rpm without any issues. And there's no need to shift higher with an XP, s1x. Put the saved money towards those 42# injectors and a tune.

    VS cam build 13.01@107 316whp/ XP build #1 12.78@110 334whp/ XP build #2 12.56@113 347whp
    IS3 Cam build (Ready to put out some serious numbers)

    Or 105s and a stock chain. More forgiving on the chain and dampener

    take the turbo build route and get your big numbers. To get 450 CHP off a SC will be one hell of a build. you want those big numbers, go turbo

    ^Agreed. Go Turbo. Granted, there are m90 bulids in the 10's. But its rare and triple the effort.
    I'm hoping to see11's soon but I'm not expecting it. After this, I'm gonna have to get realty creative

    gotta pay to play. you want 400-450 CHP? you go turbo and build your own turbo kit and get a built transmission. itll cost more in the long run to get that much power out of a supercharged car.
