Top Of The World to you the66mustang!
My friend has an 1984 RHD Opel Monza CD, so can you put the Lotus Omega 24V head in the post, and send it and the turbos to New Zealand?. I'll buy his car and strap that head on. Who cares that its a General Motors product when its got 370 horsepower!
The Opel's Bosch injection set up would be perfect if the intake runners line up. It's not cross flow, so its the same set-up as a US I6!
Info For your Benifit:-
24 valve twin cammer Ford I6's have already been in Australian production since September 2002! Australian Twin Cam Falcon sixes use the same bore spacing as the 144-250 I6'S, and only recently changed from the 250 spec con rod (5.88 inch/149.4mm long centre to centre) and basic crank design for the 4 liter SOHC six. Stroke is still the same 3.91 inches ( 99.314 mm) that the US 250 came out with in October 1968! There 35 years of lineage to the lastest DOHC 24 valve Intech I6 in the Aussie Falcon, almost 44 years if you count it as a realative to the first October 1959 US Falcons! Bore spacings, centre to centre, are 4.045 inches (102.74 mm) for all US and Aussie OHV and S/DOHC sixes!
The Australian GM OHV 130/138/149/173/179/186/202/2850/3300 Holden six and 1900 Starfire four has the same 4.045 inch spacing as well. Just why the arch rival of Ford would copy it is the possibly the same reason a Y-block v8 has the same bore centres as a Small Block Chev!
The Opel engine is very different to the Holden six. I suspect it was totaly metric. Wasn't it 1968 when it came out? The cam in head OHC engine wasn't thin-wall, and was heavier than the Aussie 253(4.2liter) and 304/308(5.0 Liter ) V8's. Peter Brock, nine times Bathurst winner and Holden race driver, said the 1984 Opel Monza3.0 GSi engine was Chev V8 weight at around 245 kg (540 pounds) rather than the 207 kg (456 pounds) of the Holden V8. The bore size was up to about 3.75 inches (95.2 mm) in the 2000/2400 Ascona fours and 3000/3600 Omega Sixes. The fact that Enrich Bitter threw in a stroker crank to 3.9 liters vouches for its durability! My guess is the bore spacings are more like the 4.125 inches( 104.78 mm) that it's English OHV 2.6/3.3 liter Vauxhall Cresta 6 cousin had.
Boy that Lotus Omega was such a weapon. Germans do carry guns!
