 Unfortunately I cannot, but speaking of Strange Rovers at the recent Classic Motor Show

a rally spec 2-door P6 with 4 litre motor was on display promising 0-60mph in 7 secs :smoking:

What is it intended for?  Not eligible for any historic rallying, and not competitive in modern rallying.  The bull bar suggests long distance endurance type events?

Originally a Traco-Olds engine...

And the engine was never so far back as to say it was 'mid-mounted'.

As an aside, the Buick and Olds engine were similar but not the same. Why defeats me but one had a different number of head studs to the other among other differences. Who knows which was which and which one the Rovers ended up using.

I think I used to know :evil:  but have had the odd sleep since last working on a [by then] 4.4 Leyland engine. 

Traco modified Olds engines, possibly by arrangement with the factory or dealers. I thought Repco based their engines on the Buick?  Presumably the one with more head studs would have been the better bet?

Thanks. Wonderful photographs and the car looks just as good in blue or red. 550bhp with that wheelbase, no wonder there is a lot of rubber. Not just enough to get from A to B, but from A to Z and back again. I really like cars of that short, squat stance. I saw a Dolomite Sprint that I really liked at Donington one year, this Rover is even better.

Repco-Brabham V8s were based on the Oldsmobile block...

It was the one with fewer head studs, but they made up for that in other ways. It's altogether possible that the Buick arrangement was because it was easier to do with the traditional Buick-style rocker cover mount angle.

On the other hand, I feel certain that the Rover and Leyland V8s came from the Buick base.

Oh yeah, the Rover might have had wider rubber if our rules didn't limit it to 10" wide rims...

Though cars owned by Moffat didn't have to stick to that rule.

If you are referring to the Monza it may have done one or two events in DeKeon form. It seems the race organisers wanted it legal or not.

Though I doubt the tyres were any wider, just suited the rims correctly!

Many classes in that era used very wide tyres not really suited to the rim width, in some cases even the manufacturers specs. 13-14" wide tyres on 10" rims was stupid, the tyres rolled all over the rims and in effect you were using about 2/3 of the tyre.

IF the rules were ever enforced the majority of competitors with V8 Tourers and Sports Cars and Sedans would have been disqualified. 

Better these days though there is still many with huge tyres on narrow rims.

GpNc with the 275 wide tyres on 8" rims. Though the book does say 8-10 " wide rims. Unlike the past where the recomended rim was 11-14" with cars racing on 10" wide rims.

For the best performance any race tyre should be on the maximum size rim, not the mininum.

I don't doubt that he might have done so with the Monza...

But I know that Frank Gardner picked him for having 13" or 14" wheels on the back of the Capri at Wanneroo.

I worked on a Monza that was running 12's. Though they were 10's by the time they had the tyres stripped and the wheels measured properly. (now you see it and now you don't)

The fronts were stripped instead of the rears?

Frank's approach, on seeing the size of tyres Moffat had fitted, to ask how the service he was getting to Goodyear was. And once answered he made reference to them being pretty good to get those huge tyres on 10" rims. I gather the following week he had smaller tyres and rims when he ran at Adelaide.

Something like that but not quite. Was funny though.

BARC ran the Burton sprint around the factory in Leeds. They still have "The Burton Trophy" which is now awarded at one of the Harewood meetings.
 
 
I did once see a Land Rover sprinting at an event at Leconfield airfield (aka Carnaby 2).


Did someone mention Land Rover ?

No Repco-Holden F5000 engine ever gave that much power, perhaps 525 for the best of them...

But it's more likely it was a 90° crank rather than a flat plane in this one, while it's also very unlikely it had the very latest of mods that Repco did for their top engines.

It's way more likely that this installation saw about 480 or so bhp.

Thanks Ray, I admire engineering but am far from technically minded, so just had to go with what I'd read online. Still, I'm sure 480bhp, to quote Rolls-Royce and Bentley from the past, is "sufficient." :)

Yes, thats right.  In fact, when Rover were developing their version of the engine, they employed an ex-Buick engineer (Joe Turley?) for a while to help with his advice and experience.

More than that...

They have many better components today, more proficient flow benches and operators, better cam profiles and they push them further because those better components let them.

Better heads, better and lighter pistons and rods. 

Reputedly in period they made high 400s and probably 80 more now.

Speaking to Chris Milton at Mallala a couple of years ago he reckons with a Chev there is a 100hp. That is just with internal components. Everything is lighter, cams and valve trains are a LOT better, and yes porting is better too. Though why use period heads, all the aftermarket stuff is a lot better and cheaper to develop too.

Different. Keep the crowds happy. Less aerodynamic though than  57 Chev. The tent should be good at 100 mph plus!

I've been told that the best Chevy F-5000 engines had about 540hp around '77/'78.

Probably with the then ultimate Brownfield heads. Which were a bit iffy keeping the water where it was supposed to be.

I had a pair of 292 Chev castings, originally from a 5000 and used on the VesKanda Sports car originally and they flow a lot less than a Dart 2 head which supposedly are about equvilant to a Brownfield or early Dash 8 Brodix. These days they are mild street heads!

That is the development. The supercar HMS [Chev] heads are probably a 100 hp better too. reputedly they make 640hp these days. But only about 420 ft lbs of torque. Though those heads really are a clone of a Ford head. Canted valves, equal port spacing etc. They are the junior version of what Nascar used before they went totally racing engine.

360 Sprintcar heads are 23 degree and make about 640 too these days though they are turning them VERY tight at over 8500. Those heads on a 5000 would make similar power with a good deal less torque. But again have to be turned very hard.

410s are off the planet, [besides drag race stuff] that is why they make 800 plus these days but again over 8000rpm. Both capacity Sprint engines are becoming very  high maintenance.

3 years ago a good winning 360 here in Oz would do 20 shows with routine maintenance, now it is about 8 with far more maintenance. I am damned if I know where the money is coming from now with the AUD at about 84c to the USD.

Quite likely they did...

But this conversation is about a Repco-Holden F5000 engine, based on the (quite different) Holden 308 V8.

Then again, Repco figures were often a bit on the conservative side, with his 525hp engine John Walker could pass anyone up either straight at Sandown any time he liked in 1975 so easily he didn't even bother to try to win the start from pole position.

Repco had a team that was way ahead of any of the usual tuning shops, very professional and very capable blokes who actually made a lot of the gear they worked with as well.

Sometimes you need to follow things closely, skip over some rubbish to keep up with the story.

I remember the Camel filter Rover competing frequently at Calder in the SS Series.
If I remember it went like stink but seemed to suffer from reliability problems.

I think it was James Smith that was the driver at the time.
