How did the small block Ford V-8 reduce weight?
How did the small block Ford V-8 reduce weight?
More iron in the main webs permitted elimination of block skirts found in earlier Ford V-8 designs, which reduced engine weight. The small-block Ford V-8 was a quantum leap in lightweight engine technology at the time. This Tech Tip is From the Full Book, HIGH-PERFORMANCE FORD ENGINE PARTS INTERCHANGE.
How big is the intake valve on a Ford small block?
Intake valves are 1.670 inches. Exhaust valves are 1.440 inches. What makes the 289 High Performance head “high performance” are valvespring pockets for stability, along with screw-in rocker arm studs engineered to withstand high RPM when compared to press-in studs.
What was bolt hole spacing on Ford small block?
These early blocks are also differentiated via engine mount bolt hole spacing, with the earliest 221/260 blocks being 6 inches apart along with two freeze plugs instead of three. Changes to three freeze plugs and different engine-mount bolt hole spacing happened early in the 1963 model year to reduce NVH.
What was the compression ratio for a 1965 Ford small block engine?
Valve sizes remained the same. For 1965, the 289-4V engine went from sharing dished pistons and the same compression ratio to 10.0:1 and flattop pistons. All pistons, flattop and dished alike, had valve reliefs. The 289 High Performance V-8 remained virtually unchanged aside from the six-bolt bellhousing block and a higher compression ratio.

What kind of bell patterns do Ford engines use?
The following is a list of Ford bellhousing patterns. A list of bell housing patterns for General Motors transmissions is also available, as is a list of engines for Ford Motor Company. Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some “big block”-sized V8’s as well as some V6’s and I6’s.
