    heres a link to some useful suspension info.... reading thru the sub linked info could take a few hours but be well worth the effort

    heres a few corvette stock and aftermarket 3rd generation frame pictures to give you a few ideas, its sure not covering every option but it might be useful,
    some of the pictures below are designs that are 30-60 plus years old, that still work fine ,but by today's standards are archaic and can be improved upon

    This is a fact lots of guys seem to ignore, a good deal of ingenuity by a cars builder in selecting the components he will use and and a great deal of thought going into getting a good power to weight ratio ,and setting up the frame suspension and brakes and drive train, regardless of the cars appearance, can result it some amazing performance characteristics, but some thought should go into the cars aerodynamics and interior occupant comfort , along with the cars braking ,handling acceleration, and over all looks.
    now obviously its far cheaper and easier to build and modify an existing car as a starting point but that has built in limitations, you can go with several dozen kit cars or if you have the funds and several skilled friends you may take a crack at designing something totally new.
    purely from a point of physics, a 4 wheel drive,drive by wire control, mid engine, car ,with a reasonably powerful aluminum block V8 like the current mopar third gen hemi or current GEN V LT corvette engine with a 5-8 speed automatic transmission, could be built by anyone with the access to the internet and the skills to do the required research, plus the will, and cash and tools and a place to work,that allow them, too actual follow thru and build the car, once the design is perfected. Id bet easily 90% of the parts required are already being produced for other applications and it would simply be a mater of finding out what IS available and what might need to be fabricated to build the car in the case of the few components that were not available "off the shelf" some place, other than obviously parts like body panels , glass, some of the interior and the frame itself that would tend to be unique, BUILDING a sports car with a computer controlled, independent suspension and 4 wheel disc brakes, at least from my perspective, sure would seem to be the ideal sports car design, especially if it could be built to weigh under 2800 lbs and to have under 5-6 pounds per hp at a reasonable cost, sure would seem to be both a reachable goal and nearly ideal with todays current ,engine, suspension,braking , drive train, and computer technology

    OPEN YOUR MIND AND THINK OF THE OPTIONS....YES YOU COULD BUILD IT IF YOU WANTED TOO!
    you would be amazed at the components you can find for sale in salvage yards or on ebay, or if you put out want adds

    STRANGE ENGINEERING NOW SELLS A DANA 60 IRS DIFFERENTIAL with the DANA 60 9.75" GEARS
    yeah pricey but far stronger than most other options and it retains the IRS differential for road racing traction

    a 4l80E could be built to easily handle a decent chevy V8 power range so who makes a decent durable 4wd transfer case that could be used and a front wheel drive independent suspension to use on an AWD sports car,thats potentially compatible with building a awd mid engine sports car?
    Im looking to find a transfer case to bolt into a custom built hot rod behind a 4l80e to convert to awd, and suggestions
    Oh and obviously the FWD differential
    I can fabricate most of the suspension if required but the more off the shelf parts available the better, it would seem that the drive train out of a 4x4 truck might provide a great many components that could be adapted, to build a mid engine sports car if some engineer or serious hobbyist were so inclined
    what transfer case fits the 3500 series 4x4 chevy trucks?

    I'm curious as too how many guys have any desire to build a mid engine V8 powered sports car type hot rod?
    Im thinking that if we pool our talents and do some research, surely theres got to be several people who have already designed and built cars on that mid engine/ v8 powered format and by looking over and combining the previous designs for suspension and power plant, and power train design and the parts used in the cars fabrication,an even better composite ,using the best ideas in the previous designs could be built?

    I seen A small Group of Rat Rods driving by cutting the Lawn today Grumpy.
    None sounded real powerful as We like.
    Likely 14's-13's.

    Earlier I ran to town to get gas for the mower.
    On my way back in front of my farm house a New Blue Dodge Viper Rode by.
    Then A Sunburst Orange C6 Corvette Following.
    Got me thinking.....
    Like our other Forum Digital Corvette...
    None are Drag Racing.
    So many Excuses.
    Ironic the guys that want to like us need $.
    The guys with $ are Sissies.
    Won't Race.

    Be a while Grumpy.
    9 -Second fast could be built with A Big Block & T-bucket layout.
    I won't screw around with IRS Rear.
    Solid axle only.
    Race Hard.

    I've always thought that ID like to build a dual engine car just because it would be both some what unique and impressive, but like BOB mentioned I'm wondering how practical it might be to effectively couple two chevy big blocks nose too tail and wonder if there's any easy, and well proven, way to do it or commercial kits or at least detailed instructions with diagrams posted by some of the tractor or truck pull crowd that regularly deals in that type of drive train configurations.
    yeah! Im fully aware that the power to weight ratio, handling etc might be better with a single engine, in a well built car, but obviously this is partly about WOW factor and pride of engineering skills and having something a bit unique and not practical.
    and yes I've also thought of a 4 wheel drive car with dual but separate engines, where a front engine drives the front wheels and the rear engine drives the rear wheels
