    i mocked up all the changes on this sport coupe body and im looking for opinions

    the body is shortened 3 inches in the door area...channeled 4 inches...the rear of the interior is brought front 4 inches and lowered 3/4 of an inch then a body line added to the top and along the bottom (like a roadster)...everything is smoke and mirrors in this picture...well masking tape and a cardboard door but i think i have all the lines figured out

    just wondered if anyone sees any problem areas...seems ok to me...but nothing is welded yet so i can change if the need be

    thanks
    zach

    Someone, posted pictures of some Miller Race cars a week or so ago and I was amazed and in awe of how every part, every dimension of the ch***is and how the body hood a radiator shell fit was an integrated part of and dependent on the whole of the motortrain and ch***is.
    The radiator shell was placed where the radiator was, not the other way around, the firewall was placed at the rear of the engine, not the engine squeezed in in front of the pre-located firewall.
    The pedals were an integral part engineered into the bell housing and the seating was located relative to those controls, again, the seating was relative to the size and shape of the engine and motortrain, not the other way around.
    I guess what I'm saying is, to "look" right the prewar car needs to have the clutch pedal located where it swings at the back of the bellhousing and the seat needs to be located that way and the body needs to follow the seat and the rear axle needs to go in the middle of that wheel opening, where-ever it ends up.
    And the hood(?) needsto span the gap between the length between the firewall, the firewall that doesn't need to be indented into the footroom becaus eit's in the right place in the first place, and the radiator shell that's located where the radiator needs to be, not the other way around.

    If you're running a four banger, your proportions are probably right on, but if it's an inline 6 or long V8 like a Ford MEL then it's too short.
    Whether the door is the right length or not depends on where the pedals and therefore the seats are going...

    I think the drive train needs to be mocked up in the ch***is, with the rear axle location still adjustable before deciding if the proportions follow the logic of the ch***is engineering or not.
    The hood should be as long as the engine lenght requires it to be, no more, no less.

    In hotrod design, form follows function, always.

    thanks,
    i know what your saying
    everything is measured out for the lines to work out nicely i think

    basically i guess what im asking is...did i fix the stubbiness of it being a coupe?

    i have the front crossmember located 1 inch beyond the front pulley on the crank of the 302 that im going to run...its going to be a (cringe) automatic so the clutch doesnt matter too awful much but there will be ample room for the pedals with the c-4 ****** where it will fall...the rear wheels are going to be centered in the wheelwells but above the opening....and the nose in this picture is actually an old late 40's nose thats too small for the car....but it gave me a line to look at

    anyways....what im getting at is....everything is being planned to fit...but i want nice lines...not a stubby backend or anything....i guess its all what pleases my own eye anyways.....

    thanks alot
    zach

    heres what im shooting for
