Stroke a 318

i think @MonkeyMadness has a 392 stroker in his D series truck? maybe he can weigh in.
Yep, my D100 sports a 318/396, 4" x 3.970" (.060) stroker. I got the kit from CNC-motorsports. Couldn't be happier! Easy install no block clearancing needed, due to the I beam rods. I went with the 9.3:1 kit but then I added the felpro head gaskets 1008 and a set of CNC speedmaster heads and it runs like a raped ape... I love it!
