Fellows,
This is Brasilian built speed equipment. Engine makes a bunch of parts for the GM L6. They are well done. And of course much cheaper for us here than the Clifford of Offy parts. They have a cool valvecover, side cover plates and a bunch of manifolds. Many years ago there were some other options made by Envemo, there were a 3 single barrel carb manifold, had finned fibs between the carb mounts and looked pretty nice. Nowadays almost impossible to find one. As I have said here before, due to many particular politics here concerning the car industry, we had the 250 chevy produced here tillalmost year 2000, using Multipoint fuel injection, 12 port head, one piece rear main seal, longer 6.000 rods, thinner rings and so on. Now they are gone, but still possible to obtain complete engine sets.
