*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.
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.

OIL FILTER: (see XRV8 oil filter picture album here)

Baldwin B-9: 'medium flow' 20 micron rating, Made in USA!

Baldwin BT-350: *Largest diameter, no anti-drainback valve, no internal bypass, adds one quart to stock system

Baldwin BT-525: *Longest spin on filter element, with anti-drainback valve, no internal bypass

Fleetguard HF6001: 6.82" long, 3.81" diamter, 13/16"x 16 thread (stock RV8 thread size)

Fram PH11: 'Long style', no rusty cap on filter media, no bypass, medium micron

Fram TG5: Adapts by using AMRV8 oil filter gasket. This unit has finer micron 'composite' filter element but still suitable for 10-40W oils. (don't use oil filters designed for the newer thinner synthetic oil: too restrictive & AMC V8 clearances were not engineered for such thin oil) no internal bypass, made in USA

Hastings LF212: (Baldwin owns Hastings? Made in USA)

NAPA Gold (WIX 510830) -same specs as Baldwin BT-350, no internal bypass, adds one full quart to system

Purolator L30005: 'Long style', quality product (German ownership; MANN Filter)

WIX 51049: 'Long style', quality product, 21 micron rating (German ownership; MANN Filter)

WIX 51830: (same specs as Baldwin BT350*) no anti-drainback valve, 25 micron rating (high flow/lower restriction)

*Baldwin's prefix/suffix chart says 'BT' means 'spin on lube or hydraulic'

*Baldwin info: indicates only about 10% of engine oil goes through filter on stock bypass system, see also p45; BT filters use composite media and show 20 micron filtration ability (despite Zoro showing 27 micron rating)



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

Someone said 'You can lead a horse to water, but you can't make 'em drink.' ...how about filtered water?

The stock Rambler V8 oil filter mount employs a built in bypass which uses an arguably weak spring. With only about 10 psi. backpressure from the filter, the bypass circumnavigates the filter and feeds unfiltered oil to the engine.

To make matters worse, many oil filter makers offering oil filters for Rambler V8 incorrectly incoporate an additional internal bypass in their design; this makes two bypasses ...to make double sure your engine gets served unfiltered oil!

My opinon: 1) Investigate and make sure you don't run a filter that has it's own internal bypass. 2) Run XRV8 RP no bypass oil filter mount for full time 100% filtration only. 3) Double your filter change routine instead.

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

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



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.



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

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...

TIMING GEAR SET: (See Camshaft Timing) Note: Gears do not use a chain! Chains use sprockets.



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.
