    Heart Rate fun

    My (rather painful) record was at the end of a long whitewater slalom course at the World Masters in 1998. I was 52 years old. Approximately 200 bpm. I wasn't sure I was going to survice, but at least I won...

    Early planning options on transaxle

    Then you'd probably be better off with a 302/331 (~350 bhp) with Webers for show.

    Chassis plans

    I suggest you do some measuring before you buy a 429 series engine. It's quite a bit longer than the FE, even the SOHC version.

    Oil Pressure Reading On Cranking Over

    Coolers are non-directional but oil filters have a check valve to prevent reverse flow. Plumb them backward and you get no oil pressure or flow. In a filter, oil always flows from the outside into the center.

    Oil Pressure Reading On Cranking Over

    If you are using a remote filter, make sure that the connections are flowing oil in the correct direction.

    Mk2 nostril hinges

    Move the pivot point back, onto the main body. That will increase the clearance while the hood is opened.

    Brake calipers for 15" rims

    We have also found that when using original GT40 cast wheels, 11.75" is the maximum rotor diameter in the front.

    Front suspension and steering Drawings

    What brand of replica do you have?

    exact dimensions 351/427 crate engine

    I've got a very crude DWG 3D model of a 302 that includes the engine mount bosses (and some other stuff). Some of the surfaces are missing, but that shouldn't effect what you need. E-mail me at [email protected]

    Heavy steering

    This is probably due to gyroscopic reaction. Not much you can do to change it except reduce the rotational inertia with lighter wheels and tires.

    Check your ZF

    A copy of the ERA system. It even uses the same BMW slave. However, we put the bleeder at the top.

    Discrepancy in header temperatures between both cylinder banks

    The temperature variation from side to side is way too much. Measuring the temperature of each pipe near the head will isolate any cylinder that's weak. Something's not right, either mixture-wise or even no ignition at all.

    Quick ratio steering rack for G T Racing chassis (ex MDA kit)

    If it has a bolt-on steering arm, a custom (shorter) one might be the simplest path.
