Patrick I'm glad you chimed in as you can enlighten me about this. I am wanting to build a mileage sb for my early dart & I was thinking of a 273 rather than a 318 & I was thinking that there was a comprehensive thread awhile back that detailed the ills of doing a 273 but I could not find it. A 273 would be a bit smaller but if the pistons are way more $$. What are your thoughts?
