I have a 69 vert. with the 350 that was rebuilt at some point before I purchased the car. Car came with a two barrel than a four barrel was added, also the cam was change.
The compression on the engine is running around 170 per cylinder. The 46 heads are still on the motor. But deal is I have no idea what was done on the inside. I can only guess
it was a complete rebuild. They had installed a edelbrock 650 that was not setup the right way, I changed the jets out to a smaller set, which the motor thank me for doing.
I'm happy with the way it runs, It's not a race car by any means. I may be able to do more tuning, but for me it's a cruiser. On the highway it feels happy running around 80.
