CONNECTING RODS:
 
XRV8 Race Parts: Custom race rods made to order for AM Rambler V8 engines -cores required
 
*XRV8 RP can re-cut your rod bearing notches, to defeat the low rpm oil spurt feature, or in order to use the less expensive miss-engineered semi-grooved rod bearings.
 
 
CONNECTING ROD BEARINGS:
 
JEGS: Sealed Power Vintage 2230CP -these are a 'Tri-metal' design like the old "Clevite 77"s but have no oil spurt notch to keep more oil in the rod bearing for high rpm/race type application.
 
*Avoid buying the mis-engineered aftermarket semi-grooved rod bearings... if you already have these, allow XRV8 Race Parts to reverse your rod bearing location notches; this will keep more oil in the bearing area for greater durability past 2000 rpm.

LIFTERS:

Comp Cams 'Endure X' pn# 87017L-(x) & 87018R-(x) look to have high probability for use on custom ground RV8 roller cam (.904" dia. left and right offset) Use pn# 838L link bar (link bar for Ford SB 1.730" center to center, where c to c on RV8 = 1.714") -dedicated race engine only that will see routine teardowns for inspection

Dow Corning: G-N Molycoat Paste: Consider this for lobe to lifter interface break-in lube

SBI: VL31 -solid lifter, high performance

Sealed Power AT-2084, interchanges with TRW VL31 -stock solid lifter

 

OIL FILTER:

Fram HP2: 13/16"-16 thread, for increased GPM, screened higher rate bypass valve -true race filter

System One: pn# 216-0113, 13/16"-16 to 1"-12 thread insert -to gain wide selection of oversize filters

A few 1"-12 thread filters to consider: Fram PH3776, Wix 51820 -these add two more quarts of oil to total system capacity

 

OIL FILTER ADAPTER:

XRV8 Race Parts: Oil Filter Mount, no bypass for 100% filtration

For race application only, for those who will religiously change their oil filter...

or for those who would like to use a higher GPM race filter having a higher rate bypass spring

POLISHING:

EPI: Excellent article on the benefits of detail polishing mechanical parts

XRV8 Race Parts: Detail grinding and polishing (AMC products only)

 

RADIATOR:

AMC radiators by US Radiator but I'd easily recommend Champion Cooling Systems for a well made high performance radiator if keepin' it stock looking is not an issue on your car. The correctly sized two row aluminum for AMCs from Champion is seven pounds lighter, having much better heat dissipation & has excellent trans fluid cooler in correct location.

 

ROCKER ARMS:

Crower: custom offset rocker arms, various ratios

Galvin's AMC Rambler Parts: used and rebuilt RV8 shaft mounted rocker arms

-Adjustable, also replacement adjuster screws, or non-adjustable types

Harland Sharpe: Custom made rocker arms, various ratios

-also sells 'cup type' adjuster screws for stock RV8 adjustable rocker arms (for use with 5/16" ball/cup type pushrod)

XRV8 Race Parts: Weight matched, detail ground & polished

Rocker Arms Unlimited: Rebuild service/Rebuilt rocker arms for '56-'67 AMRV8

...if your shafts are worn, consider having them hard chromed after brazing process to fill in gouged areas...

See article on rocker arm adjustment here: Eaton Balancing

 

SHOTPEENING:

See article here on benefits of shotpeening.

 

STARTER:

Automotive Electric Services: Gear reduction mini starter

High torque mini starter -eBay vendor

 

TIMING GEAR SET: (See Camshaft Timing) Note: Gears use a 'link belt'. Sprockets use a real chain.

 

VALVES:

Falcon Global: Source for stock 250/287/327 RV8 and 360/401 AMV8 valves

XRV8 Race Parts: Cut down 360/401 AMV8 valves (1.95" intake, 1.60" exhaust) to fit RV8 combustion chambers

Summit Racing: .080" thick valve stem lash caps for .372" valve stem (works with adapted '73-'91 AMV8 valves having 'one groove lower' 4G locks... won't work on stock RV8 'one groove higher' 4G lock type valve stems)

*Demand to use only Sealed Power VK-174R 4-groove locks (the 'R' suffix means they are case hardened)

*DO NOT USE any other VK-174 locks -they are not case hardened and are known to fail in higher performance applications (ie: with higher rate valve springs!) = if the seller does not know the difference between VK-174 and VK-174R... buy from someone who does know the difference! ...hint: it's easy to tell the difference between the case hardended locks and the simple stamped steel locks by testing the metal with a mounted stone in a rotary tool -the harded locks will destroy the grinding stone rapidly, but the stamped steel locks will grind down easily instead.
