SB Road Racing/Nascar/Sprint Car/Reving BUDGET BUILD

3.58 - 3.31 = .27, a significant amount for sure.

3.58 + .27 = 3.85, getting somewhere here! A bit more than the largest stroker crank aka MoPar used to offer at 3.79.

3.79 - 3.58 = .21. This used to be a very notable increase and seen as stepping in up performance plate for sure. 386 cubes with a 4.03 bore, 398 w/a 4.100.
 
To be clear, I wasn't saying that the difference in stroke between a 318/5.2 and a 360/5.9 wasn't worth anything, only that it probably didn't make a significant difference in regards to the stress to pistons/rods/crank due to high piston speeds, nor how fast it rev'ed.
