I had a similar 340 stroker built several years ago but with X heads at around 68cc’s; my builder used Ross dished pistons (-18cc’s) and it calculated out at 10.2 compression. I would be concerned too as your pistons note +5cc’s.

Would the only

i will call my builder in the morning to get confirmation on the deck height of the block. If he left it tall +.10 I’m in the 9:1 range but if he zero decked it

I think I should call my engine builder in the morning and confirm deck height. If he left the deck height with pistons below the deck by .10 I’m in the high 8’s range but if he zero decked the block I’m low 10’s
