Sudden thought, why bother fixing the 3.9/4.0? The 3.5 is much more reliable, surely you could fit up all the D2 stuff to it. Who would know? Must be zillions of the things lurking in sheds...
Tank, Ive got a Y-block crank in my Holden 308, taking it out to 346 CI ! (Nobody does that anymore , the machining cost is twice as much as buying a 355/383/396 stroker crank !)
All this crap about F1 , how totally ludicrous ! Talk about useless for intended application .
The magic formula (Torque x Engine speed) / 5,252 = Horsepower
So a F1 engine doing 19000 RPM to make 800HP NA only has 220 Ft/lb ,really useful torque in a 4WD application !!!)
Then again a Chev RO7 Nascar engine
Does 9000 RPM to make 800 HP which translates to 470 Ft/lbs of Torque (somewhat more useful in the desired application ..)
My 355 Holden stroker puts out over 400Ft/lbs 400HP easy . on LPG ! so what !
The old holden 308/304/5 litre engine fitted with alloy heads , stroked to say 355 , is still cheap to buy , reliable to run , and injected , will still do better than 25MPG in 2 tonne vehicle. The RV8 , in anything but the standard 3.5 size is a unreliable dog of an engine .I dont mind an engine that Chews fuel if has real power , I dont mind an engine that has good fuel consumption but has no power , but what I dont like are engines that have no power and Chew the Juice !!! (and are unreliable !!)
PS , I just bought a Disco 3 with TDV6 in it , Far better than any RV8 !!
The 3 litre Formula One engine was pure Costin and Duckworth, no Ford input other than money. Ford's first Indy engine post WW2 was a pushrod 289. Next Ford bought an Offy 270 from Meyer & Drake and copied the top end making twin cam heads for the Ford block. This became a complete balls-up, Offy sized valves and ports not working well on small short stroke cylinders. Then, shamelessly, Ford tried to recruit Leo Goossen and Dale Drake to fix it. Later Ford recruited Lou Meyer as their sales agent for the Indy engine resulting in Lou and Dale parting brass rags..

I think if we are going to talk reliability the Le Mans 24 hour race might be a better gauge than F1. I am no petrol head so don't know the history other than the Europeans have done fairly well in this race. I am sure that there will be Ford wins in there somewhere. Recently I understand that the Corvettes have been giving Porsche a run for their money so I expect that GM can claim some kudos for that.
However horses for courses means that the engines that are used in racing of whatever type have little resemblance with what is required in the engines the public gets in their vehicles.
Racing is a publicity tool for the marketing types and that is about it.
Precisely. I doubt if Australian V8 super cars have anything in their engines made by GM or Ford.
Le Mans no longer has the cachet it once had. It has been decades since cars raced there resemble in any way those available to the public from your local dealer. Pure purpose built and highly specialised race cars.
Formula One has little involvement by manufacturers of passenger cars. It is an entertainment business focused on television dollars like soccer, tennis, etc. Nascar is probably the most successful sporting business on the planet but it is not motor sport.
Technology became a factor from about 1963-64 when Chaparral (Chevrolet Advanced Engineering), Ford, and later McLaren (GM Performance Parts) and Porsche entered the fray and soon after race cars could no longer be made in small shops by privateers with any great hope of success.

Is this Schumaker the same guy as Schumacher?
For Christ sake, check your facts!
Just kidding.
To me F1 is the ultimate in technology where what they try filters down into cars in one way or other.
Its a showy sport and one at the absolute pinnacle of racing.
I have been to many as photographer and the whole organisation is so friggin professional, its just scary and the cars and motors and their tolerances are fraky.
Did you know that all engines are basically seized and have to have hot fluid pumped through them to get the tolerances right to be able to crank over.
Just amazing.
To those that wanted to fit a 3.8L V6 to a D2---Please don't do it.
I had one and it was useless, absolutele, the wiring was messy and there are frigging relays and crap every where for it. No good for going bush or dust.
The torque is probably there somewhere in the motor but not at a useable speed.
Get a 4.6, some head work and proper injection(haltech etc) top hatted and no-one will ever be able to tell the difference. It will last, be legal and above all reliable if done properly.
Cook any motor and they are toast, its that simple really.
Chev-Ford-Fiat or Porsche all require cooling.
Simple really when you boil it down(Joke)
Happy new year!!!
When Carroll Shelby was looking at building the AC Cobra he wanted to put a Chev small block in it, they said no because of the Vette, his second choice was Ford.
