HELP!

Does anyone have a part number for the tensioner used in this swap. I'm thinking it's not stock. This was from a Fiero Factory conversion to which I added an Allante intake to...

I used the tensioner off a 94 Camaro. From my research at the time, this was the part that most people doing the 4.9l swap were using. No guarantee that it's the part used by every swap, but probably a good place to start. Sorry...I don't have the specific part number on hand.

I don't know what the guy that did your 4.9L swap used, but the tensioner on mine is from the 3.4L 93-95 Firebird/Camaro.

Take the old one with you to the parts store, but I am pretty sure the guys above are correct. I use the same one on my SBC and LS swaps.

I have also heard that the FF used a Camaro tensioner.

The 3.4 v6 tensioner was a perfect match!
Hopefully this fixes my perpetual belt squeal as well....

Thank you all for your help!

Note that Too Short belt may seem to work but will wreck tensioners fast.
Same as 87-92 L4 in Fiero and others.

Is very possible this broke for same reason.
