Should be slightly faster... July 18, 2005, 09:32:32 PM Just picked these babies up, 255 shipped. GT40P heads.That with a 268XE cam from comp cams (next paycheck) should put me around 325 HP and 337 TQ at the flywheel according to desktop dyno.I'll let you guys know how these heads work out.

Re: Should be slightly faster... Reply #9 – July 20, 2005, 06:19:38 PM oh man, got the headers in, took one day to ship!Look like they are in pretty good condition, im going to take a dremel to the chambers to clean them up a little and repaint it, should add some decent power over my low compression heads. Goodbye regular unleaded gas :( Quote Selected
