From our point of view I certainly agree with Keith's praise for Chris Weisberg.....he's literally been a Breath of Fresh Air to those of us who've been trying to get changes made at Shelby.
I can remember trying to resolve a major problem during 1999 and 2000 and working with Mike LeFevers who was until recently Shelby's engine project director. We eventually built a go no-go gauge to help resolve the problem and I'd like to believe we helped get the machine work corrected and back to the original drawing for cam centerline to distributor bore specs....for some time they machined these two componet centerlines to close together. The original thought was the blocks were perfect and the aftermarket gears were to blame.... we bought every gear possible and worked with Mike to get it resolved. But like Keith mentioned the listening ear was one way most of the time.
Early in 2002 Mike was having problems with engines having rear seal leaks....I can't guess how much time this one took to resolve, Mike spent endless hours, seals and rebuilds trying to get it back under control and eventually resolved that it was tough to run their blocks without the original style directional seal grooves being machined into the new cranks he was using. Working with LA Ent. the better tooling was aquired during the fall of 2002.
I can remember the lifter bore chamfers, main bores not right, the
oil galley threads the lower bore areas perhaps requiring more meat....the list has been long but with continued and additional help from Great experienced engine builders such as Keith Kraft and others of us out here in the real world...the Shelby products are much improved. Like Keith we also have a real desire to use the Shelby heads but up until now the Edelbrock was a better way to go for many applications.....Prior to all this the Dove heads were one of the options as they are now.
Chris also has a head on the way to us for our R&D as he wants their products to be better and as Keith said they're willing to listen now.....it's very encouraging....
