port/polish question

[slow_one_eight]

I want to know how much horsepower could be attained from a fairly radical port/polish on the intake/exhaust manifolds on my stock (except for k&n filtercharger) one eight. It is currently at about 105 hp.

depends how you ported and where, but don't excpet anything huge unless you port match the runners on the head too. That combo results in much better gains.
