    Where are you located in PA? I'm just out of chambsburg pa.

    What's the engine going in, and what are you trying to do with it?

    The more you tell us about your build the more we can help

    Well first off the old 283 block will likely need machining to fit the 400 crank.

    There are a few different types of heads for the sbc 305 smogger none of which flow very well.

    As others have stated we need more info, much more.

    ....and Welcome to

    Welcome! Always good to add another Keystoner to the ranks.

    You can probably make the combo work, but it may be better to simply start with a seasoned 350 or 400 block to begin the project rather than trying to reinvent the wheel. Even a short block assembly from Jeg's, Summit or GM is going to get you further ahead. As stated, how about some more details on the project?
