Vk valiant 142 weiand project

No its a small block chevy kit that was a waranty claim that i got from the Australian distributor. I cant remember the actual part number of the kit but we used everything from the kit apart from the intake manifold. I did have to do some machining mods to the crank pulley etc. When i say waranty claim i mean it was damaged when pulled out of the box from new. The rotors had rubbed inside the case and were scuffed up towards the rear of the unit. My understanding is that these blowers are run on a machine and tested when new at the factory. Well it must have been tested right on smoko because it was boxed up and sent here damaged. Turns out when i clocked the rotors they were machined on a taper larger toward the rear. So i just remachined them in the lathe to square them up and put it all back together which balanced the bottom clearances to the case and away we went. Ive checked it out a few times after getting it up to temp and running it at the track and nothing has rubbed inside again.
