Hey datsunmike, quick question here. I was looking over the Jason Grey info and had some ideas to pass on to you for some education. I have the L20b as mentioned above, I just pulled it apart to see it has the stock crank with a set of Cosworth piston that are +0.50mm over. Not sure about the rods, if they are stock, haven't measured them. My question is that I want to run the z24 crank in this block like the 2.3 stroker, but I don't want to bore it any further than it already is. I would like to run 9:1 to 10:1 compression in the build, what piston/head combo would be best to achieve this? I need to purchase the head and would like to do the 280zx valves in it. I also am thinking of running Dual sidedraft Webers probably around the 36 cfms, this will be a weekend driver. Thanks for your input.
