is there a car from any other car that will work in my 88 sunbird and help it with HP

You can get one from a pfi Sunbird for a small power increase. The complete engine will work, actually.

mine is pfi

Your 88 Sunbird is pfi? Then it's turbo? the dimensions I have show the turbo and 92-94 NA PFI cams have the same lift.

I don't know of any stockers that are larger. Look through the archives for posts by motorman377, he might have let out some of his secrets. Otherwise look around for cams from Europe or South America or take a chance on a regrind.

Minion was talking about buying a custom cam in the 2nd gen forum a couple of months ago.

sinbird has a regrind cam in his. it was done at colt cams, a local shop. it works eather well, and the guy that did it has a lot of years of cam regrinding.

whats the specs on his cam
