Nick's Garage dyno's a 318 Stroker.

I thought they were post J era 360 heads but Im not 100 % on that.

I know where a 318 core is I could get for cheap. Maybe I will, I need something to do after my 340 is together. Can't hurt to have one laying around I suppose. I do have a spare set of j heads to go on it also, you may say I have "one too many sets of heads..." :)
