Hi Guys, I'm new here....I come in peace, not necessarily bearing gifts but maybe just a few good stories.....Ive always been a Holden guy. We run a Bellytank lakester in the Dry Lake Racers of Australia and may be able to lay claim to Australia's fastest Commodore V6 motor , this March just gone I did 310klm/hr or 193mph at Lake Gairdner in Sth Aus. It took us five years to build, we built just about every single piece in my little garage with bugger all , but it ain't no show car.....it's just a really big go-kart with great aerodynamics and a super-rigid frame.For instance I made this twin TB manifold... The first year out we ran 160mph with a VP motor, a shortened Aussie 4 speed and a 2.77LSD out of an XE 6, the donk had done 330,000k's out of a one owner Berlina.This years motor was Scott Taylor's old "Turbo VN" bottom end with the heads we'd used the year before and a fairly long duration cam. The lifters started pumping/collapsing at about 6275, that translated to 195 mph top speed the best average mile was 193. I've just bought some stage three heads done by Trick and Mansweto which we'll get some solids to run. We've also got a US 10 bolt rear end with a Torsen centre coming which will allow us to go down through2.73,2.56,2.41,2.28 and 2.14:1 ring and pinion sets but my suspicion is we'll never get past 2.41:1. The year after next we'll go to an Eaton blower that we have, by that stage we hope to be up in the 225-230mph range. We run in E class which is 3.0 to 4.3 litre. When we get up beyond 220mph we'll be hitting the affordable limit for us.....so....here's my question. I'm thinking about de-stroking a 3.8 to under 3 litres. What I need to start my research is a good blueprint of the early cranks the VN and the VP with accurate measurements. If anyone knows where I can find one it would be much appreciated. Thanks guys, I look forward to my time here and any help I can get to knock this over.
