    Beach balls? I have 335s on my car...quite bigger than 295s. They are essential for straight line and cornering.

    Front tires? lol. You guys are really intense. I think im just not aware of the possibilities. Im too much on the purist side.

    I assume you are running stock wheels and that will limit your tire choices. Its really not gonna be worth going to a 245/255 on the rear if you are solely looking to get some extra leg room out of the 3:73 rear axle.

    I have the stock 7 in Z28 wheels on my '73 and run 235/60 fronts and 255/60 rears. The 255 out back is pushing the limit on a 7 in rim but its very doable and after 6000+ miles I've yet to find see any real issues. The guys running the 300 series tires out back are gonna have cars that are tubbed and are much beyond what you are stating as your goal.

    IMO, save your money and swap in an OD transmission - you will absolutely love the car after its done, much enjoy the added daily drive ability, and add value to the car upon future resale.

    I was not aware of the difference but do know the ol Muncie takes a full hand to precisely maneuver the gearbox

    For servicability, adjustabily and almost bullet proof, no comparison.

    Back when the Super Street 5spd came out, Richmond learned their lesson (Doug Nash) and would only sell the SS 5spd with the LONG shifter, no options, and you can't buy the trans without a shifter.!!

    Had a old Nash 4+1 with a Hurst shifter, took "3 men and a baby" to shift it, but it had synchros in it.

    Nice Car! My rims are not stock. They call American racing daisy rims. The back rims are 15x8 and 15x7 in the front. They are from a 1969 z28. What is an OD transmission?
