Default Re: P & IH & TB porting

You may notice some seat-of-the-pants difference, especially so in the 90-92 cars. Port work on the 405 horse later models doesn't make as much of a difference as it does in the 375 horse earlier models. The great equalizer in both is port work to the plenum and injector housings coupled with a set of long tube headers and a tune.
