Thanks, that is where I was headed. Basically 273s and 318s are free engines. You can always build a bigger engine for about the same price. But, suppose you want a stronger 273 Dart with the original engine? Or suppose you have a free 273 block and dare to be different? Those rods are NASCAR quality and usually available for a couple of hundred $. The pistons are quite inexpensive and with pin about 200 grams lighter than a 273 piston and pin. 2.50 main stroker cranks are all over the place. Yes, the smaller bore limits head flow, but how much flow do you need with a 330?

Check back next week for the next installment of "dare to be different" stroker free blocks. Hint: What's 24mm got to do with it?
