I know it's a 351M/400 bellhousing... Did they come with C4's behind them, or is it a FMX bellhousing that interchanges?

Thanks!

The 351M's did come with C-4's in late 70's T-birds, Cougars & Torino's. It is a panfill C-4. I have a line on one if you get stuck, just don't know how long it would take to get.
