That's about right for a well tuned SB combo with a 508 cam and 727. I'd bet it would be faster with an Air Gap intake on it, especially with a only a 3500 converter.

The 508 is a big cam from a duration standpoint at .050 tappet lift, 248ish IIRC. If you build it, put it in advanced a bit as in 102 ICL using the 108 LSA camshaft.

I have a 508 in a 340. It sounds nasty, however, it sucks for driving around on the street.
