    Got to love lsx power. I'm building a 2001 Camaro with a texas speed 404 and a pt88. Shooting for 900hp at the wheels.

    Its like driving 150 down the straight at Indy in a stock SS Camaro and not slowing down for the corner. Sure, the car goes that fast. But that doesn't mean you should try that. Things could get ugly.

    Just because you can, doesn't mean it will work!

    I'v seen junk yard 5.0 Make more than 750HP with nothing more than heads, cam, manifold, and a fogger. It actually lasted for 4 1/4 mile runs. Whoopie!

    He's upgrading the rods and looking to solve cap walk now.

    Honestly though, almost 2000hp with off the shelf rods/pistons is pretty damn good.

    Did read the post about the NOS 5.0 did you. Rods amke power? Piston material make power.
    I'd love to build a 351 W with tin turbos to shut you guys up. Problem is, it would probably live

    Impatient, did you know if you jump off the Sears tower in Chicago, you can fly. For awhile anyways. But until you can land in N.Y., iam not impressed. Until one of these things shows its self outside of drag racing at the HP levels your throwing around, its nothing more than a alloy grenade

    Put words in my mouth why don't you. I was referring that I'm surprised that off the shelf rods/pistons made it to almost 2000hp before giving up the ghost. Well the Callies Compstar rods (rated at only 1100hp) didn't but they put up a good fight if you ask me.

    Oh, I'm sorry. I didn't realize this was an exercise to see how much power you COULD make before something took a shit. Carry on. If you blow up any more stuff with excessive amount of boost, please remember to post them as well. May I suggest a Lunati crank with a 2.2 rod pin and some BBC rods. Oh wait. Why not just build a BBC and be done with it.

    Not my setup, its some guy's in Sweden

    My guess is he built the motor and got carried away.

    If I were to build 2000hp LSx motor, It would be an RHS Alum LSx block with CCW crank, and Oliver Billet rods (with custom pistons of course). Plenty of guys going fast with LSx parts
    Best thing about LSx stuff is the square port heads are pretty much BBC territory as far as flow goes. Stock blocks also are good up to ~1700 or so hp with the right block (iron or LS2 I know for sure).
    They also have a main journal of ~2.6 so they are better than Gen 1 SBC also (except for 400 mains).

    Also, 1948hp isn't bad for a 427 with measly little 235cc intake runners and 33psi of boost.

    You were grinning when you posted that right. I mean you really knew better didn't you. And I is a RHS LSX block at 9.750(less than a head gasket difference to a BBC) still a small block? Or is it nothing more than a puny bore big block?
    Wow. A whole 2.6 on the mains. That sure as hell will put it right up there with the BBC in the strength department now won't it. So whats the stroke on that LSX to get it to the same cid as a BBC. Wanna try to convince me the same companies that make 4.00 BBC cranks can some how build a LS 4.25 stroke crank and manage to make it stronger? Yes the mains are .100 larger than a Gen I. And nobody ever tried to stroke a Gen I past 4.00". LS guys feel perfectly comfortable at 4.5. With 4.625 available to the brainless. Still feel the crank is that strong do you? Well I'm happy you feel that way. Build away!

    Will you say the same thing if I built a 385 Ford Windsor on spray, and manage to get it on vid before it kills the 2 people in the dyno room with it.

    you know, in another thread you said you were going to stop responding to anything related to LSx engines. could you please follow through with that? everyone already knows you think the BBC is always better. But it seems to me nobody even cares to respond to any comments anymore because of you. There are plenty of lurkers on this board that have a bunch of LSx experience and knowledge, both in racing, marine, and street car use.....you don't have any. So for the sake of those that do want to gain some knowledge and have a decent coversation about the LS platform in a marine application, please stop. Thanks
