Thanks for that Steve, do you (or anyone else ) have a picture of the Bellhousing which has the RH boss intact with alternator removed so I can see where mine differs? To be honest I was ignorant of fact that mine had been modified along the way!
And I should have said to Nate that his solution is far neater than the IDA's (especially the airbox) but not an option for us as our regs stipulate IDA's. Although jury is out on Mangusta as a race car at moment....
Nate, have you run your car ups yet? Compared to the 289 in Mustang the Mangusta struggled to breath well over 5,000 rpm, either cam needs changing to suit Webers or the headers are small than the Mustang which isn't allowing gases out There's always something!!
