no were there junk any ways
YES! You can put ANY small block Chevy into a Fiero. Visit here, http://www.v8archie.com/, there you can find the conversion kit (minus the engine) and answers to all of your questions.
You can find a vacuum line diagram for your 85 Pontiac Fiero in the vehicle's owner's manual. You can also find it at different auto part stores.
i found the diagram in the chiltons repair manual
A good auto audio shop can fabricate one for you. Or, you might try Crutchfield.com
An individual can find the tech specifications on the motor used in the Pontiac Fiero in the manual that came with the vehicle or on the Pontiac web site. There are also many auto repair manuals that can be purchased or perused at an auto parts supply store that will also have the information on the motor used in the Pontiac Fiero.
This not so rare but difficult to find part will have a cost set by the seller. Because these change hands so rarely you will just have to make a deal.
in the back of a haynes repair manual for the 1984-1988 fiero .. it has every wiring diagram you need for the whole car including wire colors .. Crosby
on a sticker located on the underside of the hood on the right side
The fireostore.com has them
The weight is either 5W30 or 10W30 The trick is to find an additive for "Flat Tappet or Flat Lifter" Engines Current oil will not protect your engine properly without this!
check the haynes repair manual for 1984-1988 fiero chapter 5 section 5. it is under engines electrical systems. it has pics also. hope this helps. Crosby
