    Just took the Cobra kit car for a run and here the results.
    Engine is a 5L roller, E303 cam, roller hi-lift rocker, World product heads, Edelbrock intake and 650 vac carb.
    Carb has been dialed in to match the engine.
    Ignition is full digital programable with a crank trigger wheel and 4 seperate coils to fire eight cylinders form a base timing of 20 * and a max dial in of 15* more. The stock distrubuter is just there to drive the oil pump and has no guts or wires.
    Car weighs about 2000 lbs with a 5 speed and a 3.08 rear.
    The acceleration is nothing short of phnominal and feels like a blower engine at close to 400 hp in a light car with two people.
    My guess for 1/4 mile time would be in the midi 11s to very low 12s.

    Ken could you PM me your phone #? I would like to talk to you about that engine set up. Also instead of running that empty distributor have you ever thought about the late model 5.0 that came in the explorers. They had coil packs and a little plug that drives the oil pump that way the front of your motor would look really clean.

    Impressive numbers, Ken!

    I would think about a taller gear though (as I'm sure you have).

    2000 lbs??!! You must be driving a shell ? That's SUPER lite! WTG!


    Good luck with it and keep us posted on the times.

    The car is a Factory Five Cobra Kit car.
    Engine is 5L roller built in house.
    World Products Windsor Jr heads with big valves, 11:1 cr.
    7/16 rocker studs with roller rockers that are same as chev.
    HPV-1, 4 coil Digital ignition.
    Cam is e-303 or Crane 2040.
    Edelbrock RPM intake.
    Carb 650 vac universal.
    Trans is 5 sps ford.
    Rear is 8.8 3.08.
    Headers and side pipes.
    Fuel is electric pump with regulator and return line with spring loaded flow control valve.
    Tires are RE7s X 9" wide on Mustang 17" rims.
    Brakes front disc, rear drums.
    Paint silver metalic with with black strip.
    Air/ fuel ratio gauge and full compliment of gauges.
    .........
    A 3:55 rear gear is being considered.
    Notes; The car is very light and will accept a lot of ignition advance in the mid range. This also mandates the use of a high value vacuum power valve in the 9 to 10 range so the fuel is richened up much quicker than on a heaver car.
    Idle is at 750 rpm. Secondary spring is the lightest one and can use it do to the engine response being so quick on a light car.
    Top RPM is unknown at the moment but has been to 6600 with hydraulic rollers.
    About all there is to tell.
