yes. Using Speed Pro H815ACP pistons with 1.5/1.5/3.0 rings. Stock hypereutectic replacements for a 96-99 vortec engine, but I've got them in a '69 Block.

I'm having a hard time finding a thread from 4-6 weeks ago that I think you may have posted in.
By chance, did you build a 350 with Metric Rings and newer (light weight?) pistons?
