    I know what you mean about a right soar ear.
    Much better to drive away from the noise than have it right beside over a long/short drive.

    How do you find that 2.88 diff?
    My wee Rover had difficulty getting into top gear and I had to change it for a 3.54.

    Cobragreyhead......it was keeping it in 5th gear at 70mph that was the problem
    4th gear was OK. Not enough torque wi ma wee Rover

    Think you'll like the 10KG weight saving on my new column


    New boss parts being made to get the wheel in the correct position for me.
    column switches required another grp cover to be made.


    Flywheel is also lightened down to about 7KG
    Told you - Every little helps.

    Should sound great with that cross-over built in. I drove mine with and without the cross-over and it makes a big difference.

    Never been much of a fan of side-pipes; they sound fine from the front/back but from the side - like a 4 pot running really badly!

    These crossovers must be a clever thing. I met a cobra owner from Tees-side whose car sounded really good. It had a 1600 four pot Ford engine with the single downpipe split into twin undie pipes just near the gearbox with a crossover further back. Sounded just like a V8.

    I find the 2.88PL and T5 B&W gearbox is a sweet spot for 351C with a low enough first ratio for launches and 2,100 rpm in 5th at 70mph. Great on long trips 23 mpg. I have flat torque 350lb from 1,800rpm mild cam.
    The previous own had built 6 cars with Chevy, strokers and Windsor . Is preferred combination was the 351C and 2.88 plus T5. You can go to a Top Loader with 351C but 2.88 might be a bit long on first gear.

    Isn’t that going to be a bit restrictive in flow? Or is the single pipe larger diameter than the rest?

    And of course, underslungs do give the best sound so good choice there

    My wee Rover is not going to set the heather on fire Jim
    A little back pressure on very little power to begin with will not be noticed.

    That 300mm section of straight pipe is slightly bigger than what was on a P5/P6.
    As you can see from my attempt I'm no expert in gas flow.
    I'm sure it'll do just fine otherwise £1250 for new pipes would restrict my cash flow
