Well found out why my 4.6 was missing......Can you say detonation? Will be going with the MMR piston kit and Hitech blower cams while the motor is out :)

Mine looked identical after I ran out of fuel spraying a 150 with the low fuel light on...mine was the #7 piston though and it made a terrible pop when it happened

thanks man... plans were to do a completely forged bottom end with crank but I think Im just going with rods and pistons, stock crank, and put some money towards cams and a port job for the heads.... even with the blower if I get to the point where that set up isn't enough Id rather build a complete separate block to swap in like a Teksid or something... My motor was surprisingly really clean... It only has 82xxx miles... So I think that set up will do what I need it to

Stock crank will hold a lot of power. It'll save you some money to skip it. It's the pistons and rods you really need.

Sweet that's what I like to hear... anyone know of a good gasket set? I keep seeing everyone offer the felpro kits for like 275-300... Anyone ever use felpro?

Were y'all not running a fuel pressure safety switch?
Because it cost to much compared to an engine! Sorry OP I suck at humor online.

Be sure to correct the tune issue before you crank on whatever engine you go with. Even a forged piston engine can be damaged with detonation. I have had very good luck with a MMR engine but have heard bad things about MMR also. So far so good with lots of boost (20+ psi) on mine with a conservative tune and knock detection (J&S safeguard).

Stock crank will hold 450hp just fine. But if you can spare the extra few hundred bucks, Id get a forged one anyway.... might as well since your in there, never know when your gunna want more power :3gears

^ This. It's not hugely expensive for a forged crank. Might as well do it if your block is all torn apart anyway. But, yeah, not needed unless you're pushing big power.
