Hey Guys, I have read the stickies and printed off a lot of material. I have a 1987 chevy p/u with a TBI and below are the mods that I plan on performing in the near future and i need opinions and feedback if at all possible. Below is a list of upgrades I plan on using:

Vortec Heads (part #12558060)
Vortec Intake (part #12496821)
Comp Cam (part #12-256-4) intake lift 0.449 exhaust 0.456

Opinions needed: Any and all suggestions needed...
Walbro 190 or 255?

Stock TBI with cop car injectors and GM production regulator (part #17113079) or xtreme fi 46mm TBI with xtreme AFPR and cop car injectors?

Custom Computer Chip from TBIChips or Fastchip?

Thanks guys I don't think I left anything out.

 

You should only need the 190 with that setup. The 65# injectors will feed it, but you might get a slight bog from a roll due to it sucking out all of your fuel. Mail order chips will get you running, but you need to get into tuning yourself if you really want to get it to run the way you thing it should.
