Agree 95%. But if this was a 100% DRAG Strip build thread we would not be talking 273, 318 or even the 'LOFTY' 340. They are totally out in todays big block stroker DRAG world. I would never think of boring a 318 0.090" to get 4 inch bore when a same weight and same size 360 fits and can easily be bored and stroked to 416 or 426 if care is taken. But why stay small block when you can have a 528 stroker big block.... for the same price as a 'Special' 4 inch bore 318.
