Rule # 1 - Never throw a Tiger part out.
Original generator has a Tiger specific fan and pulley
Original exhaust manifolds - 1 is a Falcon part the other is Tiger specific
Just when your about to throw a Tiger part out refer to Rule #1

Subject: [Tigers] Brake & Clutch pedal ratio modification
All, I sent the question last week about the stock 4:1 to 6:1 pedal ratio.
Tom H as always has a great solution ready to go and he sent his work
details. Tom's solution is great and well-engineered for those not wanting
to alter the firewall.
I don't mind the firewall modifications and since my car is a body only in
primer the firewall modification is easy. Don't look at the photos if you
don't want to see the cutting of a Tiger.

A quick run down of changes.
* stock pedal ratio is 4:1, clevis pin hole is 3" from pivot and the
pedal is 12" long.
* Needed to drill a new 1/4 in hole 2" from pivot (1" higher than
stock) for the clevis. I did build up and grind smooth some extra material
with the welder to match the thickness
* The plan is to use the standard pedal mount top hole in the
firewall.
* Once the pedal was drilled the pedal bracket needed to be shortened
and the lower mount hole moved up by 1" so I trimmed, drilled and welded the
braket to clear the higher clevis pin
* For the firewall I've cut a piece of steel plate and traced the
stock holes to overlay on the firewall
* I cut out two slots in the firewall leaving the perpendicular
reinforcement braces to allow for moving up the MCs and pushrods.
* I've ordered a 0.7 clutch and 15/16 Brake (Datsun) MC. Once I have
those and am sure of the mounting hole pieces I'll drill the plate bolt it
in place and weld it into position. Then I need to sort out the pushrod
pin length and retention.
I'm really happy with how the work went over the weekend. Please give any
feedback if I'm overlooking something critical or if anyone has done
anything similar.
Also in digging through parts I was trying to decide if I should keep or
trash parts. Specifically, any reason to keep the original Master
Cylinders, Exhaust manifolds, or generator?
thanks for looking
dan
