When I bought my '02 the previous owner told me that he blew out the #3 plug and had a helicoil installed. Now a year later thoughts of building another supercharged car are running through my head. I've heard the 4.6 2V responds very well to boost, but that #3 plug keeps popping up in the back of my head. Has anyone successfully ran a blower on an engine with a helicoiled plug? I know the best plan would be switch to Trick Flow heads, then boost it. But for that money I can do a full engine build and a blower on my 5.0.
