Pistons

[Booboo]

I am rebuilding the 4.6 in my 97 GT. I need advice on pistons. The plan is to build the motor NA at first then save up for a supercharger 7 to 10 lbs of boost. Supercharger will be down the road a ways, probobly a year or so. Right now I have the following.
PI heads with +1mm Stainless valves and BTR .600 springs, 75mm TB/Plenum/CAI, 90mm MAF, BBK shorty headers, Planning on EX262AH or similar cams.

I have a iron block and CR3Z-6200-B rods. Looking for a forged piston to go with this. Want something with valve reliefs, not real expensive but good enough to handle the hp after I get a supercharger. What compression ratio I should run.

Look in to MMR or Manley pistons. I would shoot for a 10:1 compression ratio, and maybe a cam that’s ground more for the blower.

Since you're not going with moon boost, probably ask about a 4032 alloy. Less piston slap on cold start, and better overall cold start with higher silicon content than a 2618 alloy. Less of a pain trying to ring the piston for whoever is building the engine, too.

Any comments on these? What about the rings? To go with Coyote CR3Z-6200-B rods and the stock crankshaft.

Is that for the Yote though? Seems from reading it, it's for the old Teskid or the 5.4
