    Hi all, hope you can help me. I am looking for the dimensions of a typical 4 bolt SBC valve cover. I need both outside flange measurments and center to center dimensions on the bolt pattern (bothe width and length). Thanks in advance.

    Measuring inside the valve cover gasket surface.
    19.5” X 5” outside dimensions

    <o:p> </o:p>
    [[<-3”->O<-4.5”->O<-4.25”->O<-4.5”->O<-3”->]]



    where O= bolt hole

    Im having a little trouble understanding your bolt spacing, i went and meaured what im working with, maybe you can still help or someone else will chime in?

    My bolt spacing is as follows, these are the on center of the hole measurements-- 3 7/8" x 8 7/8"

    My overall dimension is 4 7/8" x 20"---this is a little rough on this one because the flange edge it actrually turned at the edge a little.

    My main concern at the moment is the bolt spacing---and no in case your wondering, this is not a small block chevy head im working with.

    Sorry!!! Here in Texas SBC stands for Small Block Chevy. I gave you the measurements for a 1987 up 4-Bolt SBC valve cover.

    Good luck. Maybe a posted picture would help us inderstand what your trying to accomplish.:confused:
     

  5. What else does SBC stand for?
     
  6. i'm sure if you ask around you could find a SBC valve cover to borrow...then you can measure all you want. most guys that mess with chevies will have several sets hanging on the wall...in fact, in some states it's against the law not to have a pair of valve covers

    why would you want SBC bolt spacing if your not working with an SBC head?

    post #3 says your not working with an SBC head.. Title says you need Chevy valve cover dimensions

    im confused

    are you still selling that cadillac jack that you want to keep?

    There have been a lot of stupid questions and requests here lately from a lot of people who have no idea about cars nor should they even be allowed around cars. Couldn't The HAMB have some kind of entrance exam you have to pass before you can join to weed out the idiots? Just a thought.
     
  9. This guy's new, he wouldn't know about that one, but that was some funny shit.

    Come on guys dont be so hard on the guy.. Maybe he needs the dimensions cause he is trying to disguise another make engine so it looks like the more traditional SBC :)

    read first..type last..
    HAMB...traditional rods and customs
    pre 64

    now is your SBC HAMB friendly?
    if so lets talk..but you got to admit your title and first and third post got things mixed up ..go back and really read them

    Im a little pissed because i just wanted the flange dimensions and the bolt spacing dimensions of a typical 4 bolt, up to 1987 small block chevy valve cover and i get a load of crap over it. I dont know what i did to not explain that any more.

    I gave the dimensions i was working in, thought it was a simple question. The first poster didnt understand what i wanted so i elaborated to try and get help. Thats all. Im sorry if i ticked anyone off being new here. Being new here doent mean i dont know cars--that was a very big assumption.

    If you have to know, which i dont think it is relavant at all, it is a 92-02 mopar small block magnum head. I heard several times that a small block chevy valve cover fit these heads, i was trying to find out before i bought a set.

    Again, my apologies if i tweaked anyone the wrong way, i was just seeking some information.

    My guess is he won't be here very long.

    What are you trying to adapt and to what are you adapting it?

    Edit: opps, looks like we posted at the same time.

    So you are looking for pre-center bolt valve cover dimensions?
     
  23. I'll measure one when I get home, now I understand your question. No problem helping if I know what you want.

    Richard D, thank you for your help

    To the others that can criticize faster than i can type, What is what im working on and what information i seek have to do with anything? Maybe im trying to use styling / hot rod cues from cars that i like alot but dont fit your criteria. I guess the only thing i have that fits is a '25 T pickup, but that probably wont work either because its stock.

    Didnt realize i HAD to own a proper vehicle before joining. Thank you for the help for those still willing to give it, for the others, thank you for welcoming me.

    You could just stop at a parts store and get a set of gaskets for a couple of bucks........... That would show you the footprint. I'd be more worried about clearance on the rockers.

    This may be oversimplifying but....Why not just buy a set of Mopar valve covers ?

    There are about 3 or4 choices for these heads
    -Stock
    -Mopar cast aluminum--painted or polised with mopar performance logo
    -Fabricated sheet metal aluminum race car looking ones
    - a few chromed stock type ones--very hard to find

    I was looking for something alot more traditional, older looking. I have 2 2bbl holleys on a dual offy intake that i am modifying to fit these heads---also a problem, about a half dozen intake choices for these heads---non of which scream vintage.

    Why stick with a motor with so little aftermarket support, the motor has newer technology, makes great power carbed, has a roller cam stock (no more zinc in oil--causing wiped out cams) and is largely still otherwise still based on a good old chrysler small block. Plus its been swapped already into the truck--which doesnt fit your year criteria here im sorry to say.
