Visually Larger.

When I rebuilt my 302, I wanted to make it visually bigger as it looked quite small in the engine compartment (sits low in the frame). The trick I used was Ansen 1 3/8" valve cover spacers (Speedway Motors #135-4002 for 289-351w motors) along with tall Ford Racing valve covers. It looks better now. Check out the before and after below.

The tunnel ram and twin 4's certainly help also but those new rocker covers have helped too, looking darn good and you must be getting to bingo a darn sight quicker now.
