Re: Pontiac fiero
Late ignition timing could cause that-you might get more response on a Fiero forum,but the 60* v6 is known around here

Re: Pontiac fiero
It MIGHT have something to do with bolting 1987 2.8 heads onto a 2006 3.5 block, and presumably all the 2.8 fuel components designed to feed a 1987 2.8 engine. I had no idea this was even possible, and the mere suggestion is enough to make me cringe. Good luck with all that, you have bolted together an interesting mess.

You need to be on a forum dedicated to the Pontiac Fiero & GM's 60 Degree V6 engines.
There are many threads about what you want to do on these forums.
