    I had a question about the size of my engine and I wasn't really sure where to post it.

    I have an 04 4.8L v8. Any idea how big the engine is? Or any idea where I could find out?

    I know the 7.4L is like a 454, would the 4.8L be like a 290 or something like that?

    Also, for future reference, would a crate 454 fit in an 04 silverado?

    I don't think the 2 c.i. will make much of a difference, but I am pretty sure it is a 294 ci engine.
    At least when I'm searching for parts, that's what comes up.

    With enough money and ambition anything can fit!!!:lol:

    Don't see why a 454 won't fit. Some 04' Silverado 2500HD's came with an 8.1L 496ci.

    A 454 would not be a direct swap into your 04 (unless you're talking about a tall deck LSX, small block 454). If you're serious about a swap to bigger and better, I'd suggest looking into a stroked 6.0L (402-408 typically) or 6.2L (414-418). With the appropriate supporting parts, you'd have gobs more torque than you do now and considerably more horsepower than you'd be able to extract easily ($$$) from a big block.

    X2 on the 6L engine. Leave the Rat motors right where they are!

    x3, a lot of places to go with the new LSX technology.
