I had a 67 318 with new speedpro pistons i sold with my barracuda I wish I would have kept it now!

No huge loss so don't beat yourself up over it one bit ... those are still pretty low in the bores and not really much higher CR..... maybe 0.1 point. They would not change the large-ish cam challenge in any significant way.
