(Sold individually.)P4529608P4529609Connecting rod bearing, .OO 1 'I undersize.Connecting rod bearing, .002" undersize.PISTONSThe 360 AMC V-8 uses aluminum alloy pistons (withstruts) that weigh 601-605 grams (21.20-21.34 oz.) each.The piston combustion cavity is an open chamber design.For more piston (and piston ring) specifications, refer to360 AMC V-8 Engine Specifications, 'Engine Assembly'section of this chapter.CONNECTING RODS AND BEARINGSThe 360 AMC V-8's connecting rods are made of cast ironwith a total weight (less the bearings) of 681-689 grams(24.0-24.3 oz.), and a total length (center-to-center) of149.17-149.28 mm (5.873-5.877").Connecting rod journal diameter is 53.172-53.266 mm(2.0934-2.0955"). Connecting rod journal width is 50.750-50.900 mm (1.998-2.004").For more connecting rod specifications, refer to 360 AMCV-8 Engine Specifications, 'Engine Assembly' section ofthis chapter.Connecting RodThis heavy duty forging is shot-peened and Magna-fluxed.Includes high strength bolts. Can be used as heavy dutystock replacement. Center-to-center distance of 5.875".For 360 AMC V-8 only. (Sold individually.)P4529611Connecting rod.Rod RatioFor all-out modified race engines, it is recommended thata rod ratio (length of the rod divided by the stroke) of 1.75to 1.85 be maintained (if possible) for best performance.(The stock 360 AMC V-8 has a rod ratio of 1.7 1 -this isconsidered short.) Side clearance should be 0.25-0.48 mm(0.010-0.0191).Basic Preparation1.2.3.4.5.Rods should be checked for alignment; bores should beparallel. Check big and small ends for size. Use only aSunnen rod reconditioner for this purpose.Using a small file, deburr rods, paying particularattention to the mating surfaces and the tab groove. Youneed the clamping effect of a 60 micro bore. The sidesshould be polished by hand on a flat plate using #600paper.In an engine that is to used in a high rpm situation, therods and rod bolts should be Magna-Glo checked forcracks or forging flaws.A race engine should always use heavy duty rod boltsand nuts.The rod bearing clearances should be 0.03-0.06 mm(0.001 -0.0025").
