Dogdays:"The 273 cannot by any stretch of the imagination be called "long stroke". It was oversquare, bore 3.625, stroke 3.31. It had exactly the same stroke as the 318 and the 340."

You realize I referred to the LA family of motors in regards to the "long stroke" comment. Forget "imagination", using real numbers, It would be accurate to designate the 273 as the least "oversquare" motor of the LA family I believe. In threads here on Moparts for overa decade it is common for members to comment about building a "high revving little 273", and its stroke/bore ratio is the opposite of the usual ratios sought for high revving, especially relative to the other motors in the LA family.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
