Diamond makes them I believe

cybernco

Scoggin Dickey uses Diamond Racing 4.067" flat-top pistons with -4cc valve reliefs.

I have custom L92 4.00 and 4.100 stroke pistons but I have to get them as I do not keep them on the shelf. The 4.100 stroke pistons are NA only or small NOS shot and the 4.000 can take more NOS. They are from Wiseco and Diamond both.

What is the price on them?

racer7088

Well I have been doing customs so far but I am going to do a few L92 flat tops for the 4.000 stroke and 6.125 rods and 4.070 bore and they will probably be right around 575.00-625.00 depending on what options I spec on them.

Thats what i'm looking to hear. I'm looking to do a N/A motor. What rings with them, 1.5mm or the wider 1/16 rings?

racer7088

Actually depends on which compression height. On the shorter 4.100 stroke piston I have used 1.2 1.2, 3.0mm and the 4.000 stroke 6.125 deal I have use the 1.5, 1.5, 3.0mm and teh 1/16, 1/16, 3/16ths.
