performance engine on. The bores can be too thin, with corrosion from
behind, there can be hidden cracks, the main tunnels can be out of line,
or maybe you just want to build a decent stroker. The little "M" block is
ideal to build your engine from, here are some of its features- uses std
small block parts, except for cam bearings which are 2" OD. Extra thick
cylinder walls [min .275" with 4.185" bore], priority main oiling system,
blind tapped head bolt holes, extra thick decks, centre 3 main caps are
ductile with 4 bolts [splayed outer]. Extras required- BYAJG375 rear
cam plug, BYGMP-8 2" OD cam bearings, or BYGMP-8T [coated
bearings]. On the 400 block, a BY2909 seal will also be required.

Moroso Oil return Gallery Screen Kit V8
This kit is designed to retain any metal fragments or loose components
resulting from a valve-gear failure in the lifter valley area. 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.

These bearings basically duplicate the old British Vandervell bearings and are suitable for all types ofcompetition engines. V series bearings have a low to medium level of eccentricity with high crush &conrod bearings have a hardened steel back with no flash plating. The bearings are narrowed for greatercrankshaft fillet clearance. The chief difference between the V series & other Clevite 77 Trimetalbearings is the use of a lead-indium overlay. Mains have grooved upper halves and plain lower halves.Ideal for engines running in the medium to high RPM range. Lead indium overlay offers somewhatbetter comformability than lead-tin-copper overlay.

to ensure that the balancer is locked in position, ARP has developed these ultra strong
200,000psi bolts that let you exert maximum clamping force. Special features include
a 1/4” thick wide area washer, and an extra tall 12 point head that accepts a deep socket.
As the c/shaft flexes and twists, the balancer absorbs high amounts of kinetic energy.

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 BYC3817030. 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 BY31152211 cyl block, and bore to 4.155”,
use a 3.48” Eagle crankshaft, and 6” conrods. Use forged pistons BYKB762030 with rings BY3150032035,
& 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 427cu in SBC stroker, use a Dart BY31122222 tall deck [9.325”] cyl block & finish to 4.125”,
together with a 4.00” stroke Eagle crank and BYAJG580 Eagle 6.20”; “H” beam conrods with ARP 2000
bolts. Forged pistons are BYAJG590, rings are BY3150073005 Perfect Circle “Firepower” PC479,
together with a set of BY303-0319 3mm 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 6.385” 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 BY31273344 cyl block, & bore to 4.50”,
together with a 4.25” stroke crank & 6.385” 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 BY31263454 tall deck [10.20”] cyl block, and finish
at 4.50”, together with a 4.50” stroke crank, and the 6.535” 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.
All the above information is based on parts we sell, only. Remember, all
reciprocating parts must be balanced, and you must check the oil clearance
existing between the crank & the bearings. Crank, rods & pistons, must clear
the block, & each other, by a minimum of .060”.

Perfect Circle Plasma-Moly Ductile rings are designed for the serious racer. These sets feature rings that maximise combustion sealing and minimize
frictional losses to increase horsepower and oil control. These sets include Reduced Radial Wall [RRW] top rings, and CP-20 oil rings to reduce tension,
improve conformability and maximise power output. Ring sets with low and ultra low tension oil rings are not recommended for street use and should
utilize a vacuum pump for maximum performance.

Important: Check that your valve springs are not "coil binding" at full lift. It should be possible to open the valve a further .090", at full lift, with the liftersfull of oil, before the spring becomes "coilbound" or solid. Alternatively, use the valve springs listed for the cam, and install them at the correct height.
Good torque, performance gains in the low and mid range. Good idle. Can give power to 5500rpm

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.

These lifters are designed to operate at higher rpm limits, when used
with the correct preload. If you plan on running your engine past
5500rpm with a high lift cam, these lifters are safer to use. Same
fitting range as std lifters.
In some endurance uses & most oval track applications, it is necessary
to use a rev kit for the lifter to follow the profile of the cam. In the event
of a push rod or rocker arm failure, the lifter will not come out of the
lifter bore. This could save a loss of oil pressure and major damage to
the engine. The kit comes with all required springs & buttons.
Competition Cams Roller Thrust BearingThe stress placed on cams and timing gears has produced a weak area at the front of
the block where the cam gear rubs against it. This one piece encapsulated thrust
bearing solves this problem. Machining is necessary when used with oem type timing
set, but it can be done with relative ease.

Cam Thrust Buttons & LockwasherCam thrust buttons go between the cam timing gear and the inside of the timing cover.
They are mandatory with race roller cams, as the lobes are ground flat, not tapered
like flat tappet cams. This taper, drags the cam into the block when the engine is
started up. OEM roller cams normally have a retaining plate, and do not need a button.
Cam buttons can be used with all types of camshaft if the engine is used for Racing.
The thrust button controls the fore & aft movement of the camshaft, ensuring more
accurate ignition timing, and less wear on other components.
