Double check my engine builder please 340 stroke

Did he deck the block with a cleanup cut? I don't think it would be that much more to take off .010 ?? Maybe the others can comment on this?

You are running 273 adjustable rockers. But you can just measure and order new push rods. That would be a labor charge to mock up and calculate. Maybe someone can comment typical on hours billed fo that. New push rods aren't too expensive.

Sounds like he is working with a tight budget. But that's way to much compression.

In your first post you were asking about running 87 octane. You are miles from that. Was that a requirement when you were designing this build with engine builder??

Seems like a lot of duration.
The requirement was a well mannered, good vacuum, street engine, pump gas and this was a budget conscious build but not to skimp on the requirements.

I don’t understand..if the dynamic ratio at my elevation is 8.1:1 isn’t that pump gas friendly?

Here are pictures of the block
