It’s Winter. Let’s discuss strokers. How much faster

If I was to stroke a 318, I'd buy the kit and go 390. You get the crank rotating assembly. I wouldn't put a 360 crank in a 318 either, I'd just get a 360 and get the .090 bigger bore... means 360's are so easy to get.

Pistons for the 318 - 349 are hard to find. A 360 crank into a 340 block is easier. 318 - 390 is easier and a better path.
