Well, you'd have a hard time in a rally with a 2.5:1 first gear!
Been talking to Norm again. Just to put you in the picture, he's owned his car since it was ten months old. He's pretty fastidious with his cars and very much aware of what makes them tick. He's also gathered data on the GT500s because of his ownership and he was recently told by someone who is regarded as an expert that his is the most original he's seen.
Getting to the items listed by Ellis:The original fuel tank was turned around so filler pipe was at the back to meet up with the added tank easily by the hose you mentioned....not under the floor
The original tank also has a strengthening plate fixed to the top of it.
Both incorrect, though it might appear correct to someone looking at one of these cars.
The original fuel tank was tapered upward slightly on the underside to give more ground clearance further from the axle, so it couldn't readily be turned around. So they took the filler neck off the back of it and soldered a plate over the hole. The filler neck was then grafted into the right front top of the tank, while there was also a small vent hose between the tanks.
The 'strengthening plate' was probably a dealer fix after the cars were sold, no doubt a warranty job. With regular use with the weight of the upper fuel tank over humps and bumps, they found the fuel tank tops started cracking, so what Norm describes as a 'bracket' was fixed over the top of the tank. His car doesn't have this.The added tank has 3 bolt in baffles.
Good point.The filler blank off plate has 4 screws not rivets at 12,3,6,9
Covered previously with photo as well. Quite right, screws had Phillips heads.The boot lid hinge has a stopper block to prevent lid hitting fillers when fully opened.
One each hinge, correct.Boot also has a rubber mat ....(as well as interior of car mentioned).
Undoubtedly correct, we didn't discuss this.The generator bracket is strengthened. (double and welded)
Top or bottom bracket? Norm's car does not have anything different in either bracket to standard issue on Cortinas
. It does have, however, lockwired bolts on the bottom bracket and has had since he bought it.Air Cleaner was supplied in boot wrapped in brown packing paper.
Didn't know about the brown packing paper, but Norm had previously heard this. They were not a part of the cars' specifications, but undoubtedly supplied so engines wouldn't wear out too quickly (warranty...) with road use.
If they'd been fitted to the engines or mentioned in the specs, the Bathurst cars would have to use them. Clever Harry!Strengthening plates (flat with rolled lip) fitted on each side of rear inner guards.
No sign of anything like this on Norm's car. He looked under the wheel arches and inside the boot, found nothing. There is, however, a stiffener on each side mounted between the parcel shelf and inner guards, but this was on all models in Australia.
The picture shows that in the 220 I photographed the same day:
Is that what you mean, Ellis?
Further to all of this, Norm consulted his GT500 parts list. Things not mentioned so far were:Head gasket
- not the fabric type, but the original Anglia 105E gasket (copper/asbestos/steel) was specificed and fitted. The normal type were prone to failure.Thermostat
- again, Harry was a cagey old type. No thermostat was fitted, but a brass restrictor plate was put in place with a hole about the size of that in the thermostat.Double valve springs
- additional inner springs were fitted.Oil pressure raised
- a spacer was fitted behind the pressure relief spring on the oil pump.Copper-lead bearings
- I mentioned this before, just clarifying the specification.Inlet manifold roughly polished
- as well as matched to the head.
Besides this, he says this isn't mentioned in the list but it's on all these cars...Modified fan blades
- a triangular piece cut off the tips to clear the longer crank pulley bolt.
Now, to further educate our British friends, here's something that all Australian Cortinas had:
A part of the 'export package' I understand, an extension to each end of the front crossmember with bump rubbers on it. And forged rather than pressed lower control arms.
I'm sure all the Dagenham rally cars got these!
Another thing, which I can't give you in a photo, is a brace that was welded between the inner guards and the scuttle/firewall. The only underbonnet pics I have don't show these as they apparently weren't there on the 220 model... the only car I've fully photographed.
By the way, it's a 220 that Norm has in his shed for conversion to Lotus Cortina specs, and he's compared the rear inner guard detail with that car and sees no difference (as mentioned above) between that and the GT500 in that area.
