This engine right here. Was it pump gas at 12.98 -1 CR ? The highest CR of any pump gas Pontiac I know of was 12.3 -1 and it had a very specific cam and aluminum rods.
Don't think any pump gas Pontiac will live long or make the power it should at 13-1 . Certainly not without the exact cam it needs and steel rods do not help.
Was this a E-85 engine ? If the heads were close there is some reason this engine did not make more power than your new SM engine is it had the right cam and fuel in it. Its over 1.5 more static CR. Significant enough you should see it.
