can you run 11:1 on cast heads? Yes. Do it safely? Debatable. My thing with it is. i ran a motor with 11.2:1 compression on gm stock castings and the edges of the chambers debured. i had to run such little timing to keep the motor from AUDIBLY detonating that i would have made more power with a SAFE 9.5-10:1 compression. and had more fun. you HAVE to make sure your tune is right ALL the time or like me you are gunna be out there every time the D/A has a big change. as a carb doesnt give a shit. But if its something your gunna pick up and drive for fun COOL. i drove my 87 IROC back and forth to work Everyday. killing TH350's Monthly! haha
