What kind of power am I gaining with these heads?

JOE1999

  • My PI swap is complete. Before my 96 GT 4.6 2v topped out around 3500 rpm's and then took forever to gain speed. Now my engine pulls strong right up to 6000 rpm's. It feels exactly like a GT should.. Pypes catted Xpipe, FRPP 4.10's, full PI top end, 4 Bank Eliminator Chip tuned by AM Bama Specialists..

    Great for PI swap on low mileage engine. I choose these heads because with an engine with 38,xxx on it i wanted to keep good running and newer parts on it. Shop instal is a good idea with this one, there are a lot of tool that is needed to do this "properly" although you can do this at home with time and the knowledge.

    PI Swap.. FINALLY!!

    I just bought these for my 96 GT. It's a lot easier to work with assembled heads. And a lot more reasonable considering the time and expense of working with the machine shop. I have a Romeo block and putting these Romeo heads was a direct fit. I'll leave more feedback after the cams are broken in.
