Since the 3800 engine is a swap only a percentage of Fieros have them and even fewer use a powerlog. Used powerlog manifolds can usually be found for sale on the Grand Prix forums. The 3800 engines were standard on Grand Prix's for many years and many owners upgraded with them. If you go P-log on the firewall side just bear in mind that the manifold comes very close to the A/C compressor. Not sure how this has an effect on compressor life, and A/C system function. You will also get more engine compartment heat as the heat shields are no longer there and you will have a bit more exhaust noise. More horsepower for sure but I don't know about the possible negative effects, yet. IMO,using the power logs may be a trade off.

Sadly no, they still aren't stocked. I emailed and they said by the end of June. So I'm waiting on my disassemble till then or till I can snag a used one.

Sorry about that Lou. I gather that because the engines are aging perhaps they now build those powerlogs in runs. Still say best bet is to look in the Grand Prix forums. We will be at Carlisle this weekend and will try to find in the Pontiac Grand Prix section for you

I check the Grand Prix, Chicago garage, 3800 pro, regalgs, pona and other club forum websites constantly throughout the day. Im literally waiting on this part to do my engine fix and reinstall.
