We cut the offy intake center out on our racer truck and found 15 horse power , the biggest single improvement we have done. Looking at this one for our new 304 engine...

The plenum is awfully large, so I'm not sure if it will actually run well or not - especially un-blown.

One of the things that Tom Roberts and I discussed when he was making the patterns was to run long MFI injector nozzles on the sides of the plenum - that reached across/through the open area and blew down the port on the opposite side. Tom drilled the side of mine and then tapped it with the Kinsler Universal Injector Boss threads - so that different injector inserts can be used for MFI, EFI, etc..

What fuel system are you running at BVille and NA or blown?
