Avoiding the extensive damage that could result to the internal engine parts if the debris was allowed to enter the oiling system. Eight plugs are included to plug the oil return holes in the lifter valley above the camshaft. This redirects the oil to the front and rear return galleries into which the screens are fitted. Oil is returned directly to the sump area instead of dumping it on the crankshaft with consequent increased windage and loss of horsepower.

9 S3/9 - Chevrolet 4.3 V6 & V8 - Crankshaft Area S3/9 Stroker Information To build a 334cu in stroker, use a SBC 305 cylinder block bored to +.030, together with a 3.75 stroke Eagle crankshaft [not 400], and 5.7 conrods. Pistons are BYKB186030, and rings BYC A 400 externally balanced harmonic balancer & flywheel will also be required. All parts need balancing. To build a 377cu in stroker, use a 400 SBC used block or a Dart BY cyl block, and bore to 4.155, use a 3.48 Eagle crankshaft, and 6 conrods. Use forged pistons BYKB with rings BY , & bearings BYCB663VN & BYMS1038H. This engine is ideal for a higher revving Race engine. To build a 383cu in stroker, use a SBC 350 cyl block, bored to +.030, together with a 3.75 stroke Eagle crankshaft [not 400]. If you use 400 [5.565 ] conrods, then you can use 350 pistons. 5.7 & 6.0 conrods can be used, but be sure to match up to the correct height piston. Different compression ratios can also be obtained. If you are using an externally balanced crank, then a 400 externally balanced harmonic balancer & flywheel will be required. To build a 395cu in stroker, use a SBC 350 cyl block, bored to +.030, together with a stroke Eagle crankshaft and BYCRS6000S3D Eagle 6 H beam conrods. Forged pistons BYIC & rings can be obtained to order. H type Clevite bearings must be used. Using 64cc heads & a.015 deck height, the CR will be 10.93:1. With 70cc heads and a.005 deck you will get 10.47:1 CR. To build a 427cu in SBC stroker, use a Dart BY tall deck [9.325 ] cyl block & finish to 4.125, together with a 4.00 stroke Eagle crank and BYAJG590 Eagle 6.20 ; H beam conrods with ARP 2000 bolts. Forged pistons are BYAJG580, rings are BY Perfect Circle Firepower PC479, together with a set of BY mm oil rings. Bearings are Clevite BYCB663VN, and BYMS1038H. Conrods are good for 1100bhp. To build a 496cu in BBC stroker, use a std deck [9.80 ] 454 block, & bore to +.060, together with a 4.25 stroke crank, and conrods. Add the appropriate pistons & rings suitable for your purpose. With a cast crank, use bearings BYCB743P, and BYMS829P. With a forged crank, use bearings BYCB743H, and BYMS829H. The cast crank & H beam rods with 8740 bolts is good for 700bhp. If you are using a forged crank, & the H beam rods with the bolt upgrade, the kit is good for 1500bhp. To build a 540cu in BBC stroker, use a 502 GM block, or a Dart BY cyl block, & bore to 4.50, together with a 4.25 stroke crank & conrods. Add the appropriate pistons & rings suitable for your purpose. With a cast crank, use bearings BYCB743P, & MS829P. With a forged crank, use bearings BYCB743H, and BYMS829H. The cast crank & H beam rods with 8740 bolts is good for 700bhp. If you are using the forged crank, & the H beam rods with the bolt upgrade, the kit is good for 1500bhp. To build a 572cu in [9383cc] BBC stroker, use a Dart BY tall deck [10.20 ] cyl block, and finish at 4.50, together with a 4.50 stroke crank, and the L19 bolted conrods. Select the pistons and rings that best suit your purpose. 1500bhp ok. Use bearings BYCB743H & BYMS829H. This kit is good for 1500bhp, naturally aspirated, and possibly more with a Turbo or 2.

NOTES: Always buy the correct valve springs for your cam. This can avoid mechanical failures later on. Do not use a standard timing set, as these may have "retard" built in to them. Do not use performance camshafts with non adjustable rockers, or injected engines. Because modern oils have less lubricity, this can cause premature wear on flat tappet cams [does not apply to roller cams]. Use BY159 to combat this problem Most Chevrolet V8 Distributor runs clockwise.
