[1] These dampers have a 2.280 female pulley locating diameter &, upon request are supplied with an adapter to locate existing OEM pulleys with a 2.380 thorough bore. (Part #916559)
[2] Minor modifi cations to water pump may be needed to clear 7” dampers. Most effective water pumps have clearance.
[3] Requires adapter #916581, & shortening the spacer sleeve .375”, to install stock pulleys in the OEM location.
[4] Aftermarket crank with key at front, hub must be honed to fit. Hub has .150 counterbore for full length press fi t.
[5] Ford 3 bolt dampers will accept pulleys with standard Ford 3 bolt 3.3” diameter circle.
[6] For early “A” timing tab, be sure to tell your salesman that the A timing tab is needed with driver’s side timing marks.
[7] Timing marks 0-60° in 1° increments.
[8] This hub is bored straight through with no counterbore for OEM crankshafts with the keyway 1” back. It is intended for aftermarket cranks or “engine builder hone to fi t” full length keys. Request counterbore if using an OEM crankshaft.
[9] 1994 & 1995 have clearance issues with the rack. Part #918910 is 50 oz. in.
[10] Add “G” to part # for aftermarket crank. This hub is bored straight through with no counterbore for OEM crankshafts with the keyway 1” back. It is intended for aftermarket cranks or “engine builder hone to fit” full length keys. Request counterbore if using an OEM crankshaft
[11] Will not work with ‘03 - ‘04 Cobra factory style supercharger drive pulley. Call for the appropriate damper part number.
[12] Add “U” to part # for undersized specifi cations.
[13] Washer #954078 is required.
[14] All serp. application hubs have 3/16 key @ std SB 10° location.
[15] Contact ATI technician for the correct part number when used
with Ford 3-bolt pulleys!
[16] NHRA approved for new Super Cobra Jet in Stock Eliminator.
NOTE! For passenger side timing, add “P” to shell asembly part number.

Internal Balance or External Balance

Part #918910: For 34 oz. in. - 1982 and later 302 HO only. All other Ford Small Blocks use:

3 timing covers with 3 tab locations (see chart).
2 pulley styles: 3 bolt or 4 bolt.
3 different damper lengths: 3”, 3 3/8” with 3 bolt pulleys, and 3 3/8” or 4” with 4 bolt pulleys
External balance units are 28.2 oz.in. 302-351, except 302 HO part #918910 and 918913 which are 50.oz.

Part #918911 (28 oz. in.): If you install a 351 external balance crank in a 302 HO and use the stock 302 HO timing cover. The 28.2 oz. in. units will work on all external balance engines EXCEPT the 1982 and later HO provided:

The timing tab is in the proper place or you can
fabricate a pointer.
The length is OK if you’re using pulleys.

Small Block Ford Timing Tabs

”A” SB Ford timing tab engines (driver side timing) would most likely be 260 (all), 289 (all), 302-(‘67-’69) and Boss 302 (‘69-’70).

External Balance Damper - 28.2 OZ	Tab	Pulley	Length

918911	B	4 BOLT	4"
918900	C	4 BOLT	3-3/8"

How to read this chart

Locate the correct manufacturer's chart
Choose the specific engine application listed down the left side of the chart
Determine if the damper needs to be internally or externally balanced ( external balance dampers are constructed of steel only). Black bars that extend horizontally across the entire chart designate these sections
Determine if you need steel or aluminum shells. Labels for this information are listed across the top of the chart in columns 2 and 3.
Once you have determined the shell material, you need to find the outside diameter (OD) of the desired steel or aluminum shell. Then choose between 2 or 3 rings and the desired weight of the damper.
From the far right section of the chart, select either a steel or aluminum hub for your desired engine application. To determine the correct damper assembly part number that intersects is the correct damper assembly.
Assembly part numbers that are color coded correspond to the pulley mount bolt pattern listed near the top of the charts.
