Figured you would chime in Rusty. I’ll check the heads tonight when we are swapping out the rear end and let you all know. My dart is making 410 hp and that big block ford doesn’t seem that much slower but we shall see when they both get to stretch their legs.
It's a small block. I know it looks big, but it's a small block. It may have some compression. Who knows what's in it? You get the compression up in a Cleveland and they'll haul the mail. Run a compression test on it when you get time.
