couple ?s on using aftermarket pistons Been looking at the following and trying to see has anyone used any of these on a lq9..... what there opinion is about it also trying to what kind of power people are making on some slightly ported heads
LS1 Flat Top Pistons - 4.030 Bore, 3.622 Stroke, 6.098 Rod
Diamond Part Number
11510
I thought this one was funny cause its .60 over Does anyone have any info on this?
LS1 Flat Top Pistons - 4.060 Bore, 3.622 Stroke, 6.098 Rod
Diamond Part Number:
11511
this one requires rods but does it really make it a 408 with the stock stroke?
DSS1920SX LSX 408 -5cc, Flat Top, 4.030 Bore/6.125 Rod/3.622 stroke 11.5:1 at 64cc

Either of those diamond pistons would work well for a stock block with a stock style rod. I would use an 04+ rod or an aftermarket 6.100 rod.
As for that last set.....there is no way to make a 408 out of an iron block with bore alone. They must have misprinted it.
