I remember when I wanted to add some ooommph under the hood and bought a 318 with plans to build it. I then started looking for pistons to help increase compression. .. :BangHead:
I was running everything by my machinist and eventually he offered/sold me a fresh machined 340 with used pistons, new bearings for basically the same price the 318 pistons would have cost me lol.
Those Wisecos you linked would be approx $1000 Canuck pesos lol.
