Just received the latest edition of Australian Muscle Car and in there is a page story on a guy here in Adelaide who was selling a well used Bathurst Cobra (031 is the number - last Bathurst one made)
Read the story and basically 351 with a 750 holley (doesn't mention any other mods - so fairly stock) and this is what made me laugh: "There were not too many places where you could let the car stretch out its legs to 170MPH!!" I know he's trying to sell this car but come on?? I'm willing to be convinced of this but the XY GTHO was good for 140MPH but a stock 351 XC Cobra doing 30 MPH more with just a 750Holley Come On???? ![]()

They wouldnt do much more than 140mph due to gearing.
GTHO sat on 6150rpm or so to do that speed.

Even if it had longer gears in the diff it would run out of steam before 140mph... maybe 170kmh, but that's a bit sad

I can only find in statistics of the 1977 race average speed of winning car was 144kmh, or 89mph. thats a big difference.
Anyone know the top speed....? |

I'm fairly certain that John French reached 156 mph in the 1972 race in his XY GTHO phase 3 which is the record for that race class. I can remember seeing it in a classified ad when the car was up for sale decades ago. Conrod in 1972 didn't have the chicane and the 1972 race was the last series production great race. The chicane was introduced in 1987 from memory.

Hmm but if it is true (which I seriously doubt) he'd be doing it on the open road - the pictures still show the original 15 x 7 globes too!!!!

It probably has a lightened flywheel.

Just had a read on the cobra statistics, no idea if this is correct, Cobras number 2 thru 31 were fitted with option 97, optional parts fitted to allow for racing but seems limited to twin thermos, engine oil cooler and racing seats.
Maybe those cars had more 'tweaking' than others from factory. God knows what Ford actually ended up putting in them as they rolled out the 400.(or admitted to on the order. |

Well back in the day there were stories of Ph3s being flogged up the Hume at 160mph plus so I guess 170 shouldn't be beyond an XC

Nah, I don't think so, the wind drag would be way too high over 200kays to get to 270plus

Yes, there was some calculation about how much horsepower you had to add to get each extra MPH once the speed got over 100mph. It was a scale that just kept climbing exponentially. Look at the Veyron...it has to use 1000hp to punch that slippery body through the air at 400kph, and I seem to recall something about it only needing half that power to reach 300, but the other half was needed for that last 100kph, or similar.

If the XC car is close to standard then he's dreaming. It is heavier than a phase 3, and standard has less power and is fitted with anti-pollution gear for a start. The John French phase 3 car would have had a blueprinted engine and been virtually handbuilt for racing as it went down the production line. Given the French car reached 156 mph on conrod in the hands of a skilled driver I can't see the XC getting near that during open road time. Bear in mind that the XC production car was not built for series production racing but for group C meaning Ford didn't need to produce a real race car.

If it was lumbered with all the anti-pollution, then that was the dying times for the big V8's as anti-pollution regs bit hard...remember that the last 351 in the later XE ESP was only putting out about 140-odd kilowatts... |

I've heard that xc coupe HWP cars getting to 210-220kmh back in their day. Similar spec car without the the fibreglass & stripes. Can anyone confirm any higher?

Part of the reason I stopped buying AMCM. Too much myth being printed as fact.
The early production Cobra's were much like the production A9X's. The engines were less powerful compared to their early 70's brothers because they had to comply with ADR27A. When Wheels did the testing on both in '78, the Cobra's top speed was 204 KPH (126 MPH) and the A9X top speed was 206 KPH (128 MPH). I doubt a 750 Holley would make up the difference.

If my memory serves me correctly they had engine, gearbox and diff coolers and were certainly capable of 160mph on the right road.They are a rare beast and should be celebrated, not have the proverbial kicked out of them by those who are only going on what they think they know.

True, the engines didn't have to be wild, because it was group c... engine mods were practically free. Off the top of me head the bathurst cobras had - Widened rear wheel arches. Hood scoop Electric fan kit Idler arm support bracket. Strut brace. provision for a left side tramp rod, not all of them got it though transmission oil cooler String tower reinforcements modified cross member. |

All a myth I'm afraid. I was closely acquainted with Cobra 029 some years back. It was stock as delivered with low kms and it barely made more than a standard XC 351 GT Power pack on the dyno. Looked great but a bit toothless.
