excessive's 4.6 heads 69+hp

cbt · 10-01-2000, 09:52 PM

In the mm&ff the excessive motorsports 4.6 power parts come in 3 stages from ported 4.6 heads that make 69hp to fully ported motorsport heads that makes an unlisted amount of hp. Has anyone bolted any of these in the 4.6 because I want to know if the gains are correct, If not I'm going to get a supercharger first. I wonder if the heads will make quicker 1/4 times than with the superchargers.

Not sure about the performance you would get out of those heads but I would stay clear of excessive motorsports if I were you. I've heard nothing good about dealings with them. Poor customer service, receiving orders months after promised dates, wrong parts delivered or even used parts sold as new.
