    Absolutely... at 1.2 hp/cu-in, a 350 will make 420 hp while barely trying.

    A 454 makes 545 at 1.2.

    Pretty smooth idle, probably 25 mpg hwy (I'm getting 27 now with my 350) and ~550 hp and probably an obscene amount of torque...

    Who freaking needs an LS at that point? I can reuse all my current EFI hardware for hassle free install... Sell my current setup to make up some of the cost..

    Yep this thing is definitely in my future.

    Blue Print Engines called me today. They are using a standard cam tunnel block and going 4.250 on the bore and 4.000 stroke and they said they sonic test everyone of those blocks.

    Finally! Somebody who gets it when it comes to the LS craze. Thought I was the only one. Don't get me wrong, the LS is a tech marvel. But people want to sell the traditional small and big block engines short and i don't get it.

    We'll if I were starting from scratch I'd probably go LS.

    But the big inch SBC makes more sense for my situation since I don't want to tear out my existing EFI system.

    Either a 434sbc or 454sbc would be an awesome choice for your Camaro

    For a car that I drive on the street pretty often, I rather have my multiport fuel injection LS engine.

    I would only run a carb'd engine on a dedicated strip car. Each has their place for me.

    $7600 isn't bad for a 454 short block, much better deal then buildings a 383 or 406. If you have the intake, carb, and accesories, easy drop in for sure and only be in it about $8k.

    Btw Tool Guru, 575hp 454ci....LS 530hp 346ci.....people are making 700hp+ stroking LS3s. The cubes make power for sure, but it was the BBCs cylinder heads that feed big power. Something the LS cylinder head still leads on over the SBC simply improved technology.
