318 or 360? That is my question...

The car probably had a 904, the truck a 727. The 904 is lighter, the 727 is stronger. How much stronger, I can't say. I haven't messed with a 360/904 combo, yet. About 5 years ago, the SS/A record fell to a Hemi/904 combo. I'd feel comfortable with a 904 and 350 rwhp.
