3.3 p/c's on a 3.0SC?????

[hank911]

Just wonering if anybody has seen a 3.3 bolted onto a SC for displacment increase.I'm guessing you'd go with a custom set of pistons,what would be a good compression for street and what would the resulting displacment be?????? Thanks....

I'm just starting assembly of a 3.3L on an SC case. The pistons are Mahle 100mm which with the 70.4mm stroke of the SC comes out to 3316cc's. This is a set that Andial sold a while back, compression is going to work out to something in the 10.3 to 10.5:1 range, I'll see when I get it all shimmed and bolted together. Not withstanding compression, Dual Plugging the motor is highly recommended because there is a lot more distance for the flame front to travel. So if you're dual plugging running 10.3-5:1 ish compression would be a good idea to take full advantage of the twin ignition.
