    s/t lover,
    completely built 327 out of a lat 70's firebird? i think not.. 327s were produced up until 69 (or it might ahve been 68) but then they were replaced with the 350

    southsidestyle,
    if u build a 350 and a 327 EXACTLY the same except for the stroke the 350 will Typically outperform the 327, but it isn;t simply cubes that makes a motor. the 327 was a beast from teh factory. if u get one withteh powerpack/camel hump/double hump/fueilie heads with the big valves (2.02 intake) then the thing will perform great. they had like 11:1 compression or something stock (a ltittle high for street) 327s can rev real quick and real fast. the torque aint as gfood as a 350 typically, but uw ill REALLY feel the 327s power in the high end. i have a 327 with the corvette heads. the thing performs great. i think i m probably pushing close to 375-400hp. i think the 338 is a 327 bored.060 over. personally i feel that is too much. its not realyl too much, but u can;t go any further. and it wil be harder to keep cool beacsue of the thinner cylidner walls. my 327 is bored 30 over and its a 331 or 332, so i imagine that it is in fact a 60 over 327


    good luck

    every .30 you bore a mouse it is 5 cubic inches
    every .30 you bore a rat it is 6 cubic inches

    like i said earlier if its .60 its a 337

    2.030squared = 4.1209

    4.1209*pi=12.9462

    12.9462*3.25=42.0751

    42.0751*8=336.6cu

    Bore x Bore x Stroke x 6.2832

    4.060 X 4.060 x 3.25 x 6.2832 = 336.6 :D
    this is a test of the sig

    oldcarguy, I never said that 327 was a the engine from the factory in the firebird. I just know that its a 327 in a late 70's firebird, thats all I know. If I said a Blazer with a 3.4, would you tell me then that blazer's didnt come with a 3.4, or would you just figure it's one of the rare blazers with a 3.4 6cylinder dropped in...? All I know is I rode in this bird, it revved faster than any engine I ever rode in before (that is limited, what ive rode in) and when it got up to high RPM's it seemed to discover new life...

    Heres an idea, find yourself an 283 crank, large journal, and take that 327 and make it a 302.........if you really want it to turn some rpm's.........just an idea, instead of building a 350.....be different

    s/t lover,
    i didnt mean to be an ass.... u said "out of a late 70's firebird" that would imply the engine was taken from a late 70's firebird. sorry if i came off the wrong way.

    OldCarGuy - No No No, you didn't come off the wrong way, and I didn't mean to seem to be snapping back.. I'm just saying I never specified that the 327 wasnt from the firebird, its was just IN the firebird thats all.. My fault too! :bigthumb: way to look out though in case others weren't aware that it didn't come from the factory with the 327...

    TBoz - I was in a late 60's Camaro with the 302 package in it (I can't remember if it was a Z28 or an SS, I think it was a Z28 though) and I tell you what I loved the way that car drove.. I actually forgot all about that when I posted before, it revved faster than the 327 and really was nice.. This guy said that the 302 Camaro's from 69 were super duper rare...

    When you build a small block, you have to get technical with the spec's. Just my .02 cents...lol :bigthumb:

    P.S. Thank you Knudsonm for being a engineer, we need more people like you !!!:bigthumb:

    The 302 was in the 69 z28's if i'm correct....pretty rare motor, the rev like hell, and can make pretty decent horsepower numbers...

    I don't know, I just thought why not be different.....we built one for a buddy of mines 67 ss, that motor, with a muncie 4 speed and 4:11's runs like hell.......
