essential renders the cam phasers inoperable, so they work like the cams in a 2V motor (or 4V for that matter), no variable cam timing...

While I'll still need to check piston-to-valve clearance, based on discussions with Diamond and folks who have built motors with Diamond's on-the-shelf 11:0 CR pistons and using DCR's re-grind cams I should not have any piston-to-valve clearance issues running the cams without phaser limiters or...

yeah, I've been following his build and empathized when he had to make some hard rod and then piston choices. I'll definitely provide lots of pictures as well as some how to stuff, like degreeing the cams... never fun, BUT easier I hope than my 03 Cobra 4V... oh, and no bling... I'll paint the...

Thanks for sharing your thoughts, ship has sailed though... pistons are ordered... block will take a 2 mm overbore... stock is a 102 mm piston, so 104 mm is the limit, the 4.080" piston is 103.6 mm piston. So I'm essentially taking all of the life out of the block. New blocks don't have issues...

First discussion... Cam re-grind... So along the lines I discussed in my first post, daily driver, so I needed to source another set of Raptor cams to send off... If you search eBay and other sites, everyone prices Raptor parts as if they are made of unobtanium... good news, you can still...

As has been stated many times, not many options for these motors from a performance perspective. I have a 2011 Raptor Supercrew that I have owned since new... CAI, LT headers, and tune plus a number of suspension mods... While the motor has only 85,000 miles on it I've been hungry for a long...

If I recall correctly from an old engine builders article the 6.6 is a 4.080" bore (stock 4.015") and 3.82" stroke (stock 3.74") to get to the magical 400 cui. At +0.065 overbore, there can't be much more left in the block. These pistons are custom and the crank is offset ground factory piece.
