Are you running a 427/425? If so, are those heads legal? I don't think they are legal for a 427/425.

I think the only legal aluminum head for the 427/425 is the 401 head.

The 077 heads are legal on a 427/430 ZL-1, the factor for that in Super Stock is 476.

Yes, the 427/425 is a natural SS/D or SS/DA car. For a 7.5 class, the car has to weigh 3553 w/driver, that is correct.

But the 427/430 is a natural SS/C or SS/CA car, at 7.0, for a total, w/driver, of 3502.
