alright we all know that doing the stroke on the 360 versus a 318 nets more cubes as well as torque (given all things equal) and is cheaper to boot. Yeah I know about the 340 but if you ain't got one and are willing to pay a small ransom for one, you have my blessing(s). 360's are plentiful but not as plentiful as 318's but I digress. My question is durability. I was told that a 408 is not a good choice if you are actually going to "drive" the car because the piston for the 408 is too short to actually rack up mileage on because the short piston wears out the cylinder wall faster than a taller piston. Now I don't know this by experience it's what is told to me by owners of the 408's and a few builders that I know. Well, what about the lowly 318 stroked to a 390ish size? Do they suffer the same piston rocking problem or do they have a taller piston from the pin to the dome? My way of thinking is if they do AND you plan on actually logging some miles on your mill maybe the added cost of a smaller mill might be the ticket. Anyone knows if the pin to deck height of 318 strokers have a taller/shorter/same pin to dome height?
