    Trying to settle an argument. The Vortec 5300 is still a 305 & the Vortec 5700 is still a 350 correct? Some body's trying to tell me they have a 325-327 Vortec in their '99 Silverado. Any web site that has the info would be great, All I can find on Chevy's is the HP, not the displacement

    I believe you are both right. The 5300 is actually a new design 327 chevy while the 5700 is a 350. Think of it like
    this. 5300 equals 5.3 liter equals 327ci. 5700 equals 5.7 liter equals 350ci. I hope that settles your arguement.

    That's what I always thought, ecept I thought the 5300 was a 305. But, according to what I've come up with the 5300 is the largets motor available in a 1/2 ton!

    That may be true 5300 may be the largest motor available. I would like to think that is not the case but I am not sure on that one. Sorry

    They still make a 350, 5.7 liter small block, (it's really 346 ci, but they call it a 350), but only for the f-bodies and corvettes. The corvette motor makes 345 hp and the camaro/firebird's makes 325. They aren't making trucks with this displacement engine at all. The available engines are:

    4800, 4.8L, about 293 ci
    5300, 5.3L, about 327 ci
    6000, 6.0L, about 366 ci, (3/4 ton only)
    8200, 8.2L, about 492 ci, (to be offered in 2001 models, based on a stroked 454).

    So, you can still get a 350 but only out of a camaro or corvette and the 5.3 is factory rated at 270 hp.

    I'm holding out for the 8200 with the 5-speed Allison Automatic behind it. BULLETPROOF!!!

    HTH,

    Last year for the 5.7L

    The last year for the 5.7L was 1999. It was replaced with the new motors based on the GEN3 SBC, the LS1. The 350 is still being used on some commercial vehicles, but plan on them being replaced eventually.

    The largest motor availible in the new 1/2 tons is the 5300, which by the way is a 325, not a 327.

    Just being technical, but there is approx 61.5L per cubic inch. 5.3L = 325.95. The displacment of the motor is 96mm (3.7795") x 92mm(3.622") Which comes out to 325.08... GM rounded it up to the nearest 10th to get 5300. In addition the 305 is a 5.0L motor.

    For more info on it and other GM motors, check here:

    Re: Last year for the 5.7L

    a 5300 mis a 5.3 which is actually about 325, or 323 or something, not quit a 327.
    The 5700 is a 5.7 and it is a 347. I know becuase i have been following corvettes all my life and when the new one came out in '97 i was all over it. it had a new design, Called the LS1, it is 347 ci, and that is what the basis for all new GM engines is including the new line of Chevy truck motors. Oh an its not an iron block anymore either fellas, its alluminum.

    Didn\'t I say that?

    As posted before,
    the 5300 = 325.08 cubes
    the 5700 = 346.14 cubes (LS1)
    New version GM motors are called GEN III. Only the F & Y body cars use the aluminum blocks. Truck motors use cast iron with aluminum heads.

    If you REALLY wanna get specific, the old 5.7L "350" was only 349.84 cubes

    Re: Didn\'t I say that?

    I wouldn't be too upset about the 5300 being the largest engine available in the 1/2 ton trucks. They are rated at around 270-280 h.p. (versus 255 or so in the Vortec 350's). My dad just got a 2000 Silverado and, in my opinion, runs much better than the 350's.

    In '02, GM will allow the 6000 as an option in 1/2 tons. (That's 300hp!)

    In the old body style 3/4 and 1 tons, you can get the 454 still and I think maybe the 350. But they are supposed to discontinue these truck in the near future.

    For future reference in calculating cc to ci and vice-versa
    1 cc = 0.06102374 ci
    1 ci = 16.38706 cc

    The local GM dealer has several "older" style 3/4 ton trucks with 350's in them. These are just carry overs until the new heavy duty 3/4 and 1 ton trucks come out.
    About the Silverado trucks, I thought that was the overall name of the truck lineup in general....not just a specific trim level like it used to be. I'm pretty sure the new 2wd trucks on the lot had Silverado on them just like the 4x4's....but I obviously didn't pay too much attention to the 2wd's. I'm also pretty sure you can get the 5300 in the 2wd 1/2 tons.

    Silverado is..

    Silverado is the new name for the truck lineup, it isn't a trim level. The trim levels are Base, LS....

    Actually the 8.2 is the old 502 design from cadilac for the presidential line of caddy's big and fast and somehow it gets better gas milage than a 454?with the exact same fuel injection.

    Hrm? I am pretty sure that the new 502 that they are putting in the Chevy 1 tons is actually a Gen iii block. Same as the 327 (LS1). It is just bigger and badder than the 327. Oh, and guess what else. Chevy's new diesel is supposed to be bad ass. The "dura max" diesel is made by Isuzu, and it is supposed to wipe the Cummings and Powerstroke all over the board. Not to mention the fact that the 1ton engine options are the diesel and the 502 and better yet they come backed with a 5 speed automatic or a 6 speed manuel. Imagine throwing that drive line in a Blazer! If I have the money I will but the first one that is wrecked. HEHEHEHE.
