Thats why I like them too. But most think these cars are ‘stock’ cars.
Extrude Hone is in in Irwin. Wilson Manifolds is in Florida. Wilson is very well known in the EFI world and I believe they make pro stock manifolds and such. They are also well known for their CNC porting on aluminum manifolds. They do CNC work on cast iron stuff too, which isn’t something that many shops offer due to the expense of programming and the possibility of doing 1 or 2 pieces. I would imagine that it is very expensive. If the F.A.S.T. guys can run an ‘OEM’ manifold, then I’m sure it is worth the expense to them.
