[shoclown]

okay i have replacaed the intake runners with ported ones and installed BBB and now the engine makes a lot of noise above 4k? Sounds like a missfire but all plugs wires etc is new fresh complete 60k all is stock now except ported runners and bbb, ( also have pcv catch can installed)

I think your first issues is new plug wires on a V8 SHO ..... there are no plug wires.

He's gotta be talkin about a 1/2gen.

You made previous posts about 'her' feeling slower after BBB's & acid runners.

now you say you have noise after 4K RPM.
I suggested completely replacing the intake for a stock one before.
NOW suggest it even more!!
Do the BBB's have a new larger plate in them that seals well & do they open/close with no binding? Did you locktite all the plate screws?
Stock plates in BBB's will not 'feel' the same@4K. Loose screws on the plates will make noise untill they get sucked in to the combustion chamber & take out a valve & bind up a piston & then you will have some noise!

--Oh- mods please move this---!
