SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

So a lot depends on gearing which most leave as an after thought.
True. My 273 Valiant was a nice highway car with 2.76 with a 26'' tire. But getting to 65 MPH seemed to take forever.Avatar photo.
The 318 Belvedere I have now also has 2.76 with a 29'' tire has more grunt down lower.
Both engines were stock bottom end and stock heads. Edelbrock Performer intakes headers and small lift cams
.446 to .454. Now I had 4.10's in the Belvedere and it was quite a stop light performer.That was the chioce I had at the time. Gotta use what you have...
