hey all, I was wondering if .040 over pistons (oe cr, of course), add any power to the 85-87 si ew engine?

I ask this, because I just popped my tired old engine this weekend. I may have access to a good running engine that is stock, which I can do a ring and bearing job on and get back in the game sooner.

If I have to build an engine, it will take at least two months out of my racing this year, so should I get something put together quickly, or do a full build?

suggestions?

Thankfully it waited until the race qualifier after completing the double school.

Do both?
Run a stocker, and build up a spare. It matters, but if you are not already hanging out in the lead pack, then probably better to focus on driving and chassis setup instead of engine..
