If we work this out properly , we may have an alternate source for reciprocating parts. The 3.0 uses the same rods as the 2.5. The 3.0 has a larger bore, meaning bigger pistons to match. The 2.5 can't easily be bored out to match the bore due to press in cylinder liners, that's why people are swapping the 3.0L short blocks. ------------------ Brad Noon '99 SE MTX, finally supercharged!!!! http://www.bnmotorsports.com Brad Noon '99 SE MTX 3 point oh my God H.O. 179HP/178TQ BNMotorsports Floormats, powder coating, TB optimizing, Gutted cats, etc BNMotorsports is now the preferred distributor of Contour/SVT/Mystique Indiglo style gauges!!! bnmotorsports@msn.com

The big question is the height and the pin diameter. Getting a forged , lower compression piston for the Duratec would open the door for forced induction. my 2c flacoman

I'm actually considering this, I just don't have the money for the 3L yet. ------------------ Joey 2000 SVT Black #1811 of 2150 MODERATOR www.svtperformance.com If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins.

Maybe 1.5mm overbore with custom pistons. (that's 158ci or 2.6 litre) Not a big change. But yes possible and with custom pistons you could dictate your own CR. 2000 SVT #674 - Check it out!

I've also been looking into this cause I don't want to get forged pistons but I want to use hypereutic (sp?) pistons. Email me, I think I might be able to help you out on the piston specs. I've found some 89MM VG30 pistons, but they are too costly for me $1500+ David Zambrano svt_mondeo at yahoo dot com CSVT E1 #4808 - soon to be 400hp You get what you pay for.
