Carb is an edelbrock, set as it came out of the box except i adjusted the mixture a bit i know the valve lash is supposed to be .020 intake and .022 exhaust it has a solid lifter cam. it runs ok untill it hits like 2200 rpm right before the water meth injection kicks in now i do most of my driving at 1500 rpm or less because i have the stock 6cyl gears in the back. it has been fouling out plugs but they are too cold i was told it had a ar133 i bumped up the heat range to a 134. it runs a little hot like 210 215 i will do a compression test tonight and a leak down test too. thanks for the input.
