manifold question

[bens7d2]

This is probably a dumb question, but can I use just the ported upper manifold (3400) to replace my stock 3400 piece? Has anyone done this? Comments please



Thanks,

sure you can.. but i doubt it'll make any difference.

If you want something noticible put on a 3500 plenum, make sure to gasket match it though.
