273 Freshen...pic

I liked the use of the Cometics. I wouldn't build a serious 273 or 318 without them now. I think I would have liked to see good pistons and the bores fixed. But I think you're right. With the homework youve done and the steps taken I don't think 325 is a bad estimate at all. All depends on the cam... What's the duration and LSA on it?

Oh the pistons...don't get me started...but they were new and I had no idea of the shape the bores were in...this engine only had a 1000 miles on it...
It'll be OK though...The cast alum pistons are heavy and the pins weighed 257 grams....We had 318 pins ground down to fit the little pistons and saved over a 100 grams a pin.
I'll get some forged JE's when the ring pack gets loose on the cast pistons...everything else is done to the max that I could think of except the pistons...
The cam will make the power...230ish and 240ish @50 and it's on a 109 because it's a small motor...
