Somehow missed your build but I am in the process(last 6-7 months or so) of putting together a 292 for turbo/tbi style injection. Shortblock is complete. Did you at all poke around the idea of a Borgwarner EFR series turbo for the twin scroll design and internal boost management?
Also, did you install steel top rings? The Ross pistons I purchased, when the machine shop looked up the part number, said they were cast. Any concern of shattering a top ring? Total seal gave me a reasonable price for the correct rings. I left .013 deck height with dished pistons and was concerned about 10 psi for a daily driver. Are you going back after 15 psi? Sorry for a bit of a scattered post and questions.
Btw, nice build so far. Everything is coming together great. A lot of attention to detail.
