DART BBC Sportsman Cylinder Block C.I. 4.25" Bore

These days it is getting harder to find a decent block to base your 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.

Dart have designed a user friendly block, with the features needed for today. The lubrication system is a true- "priority main" system that feeds all the main bearings before the lifters. A stepped main oil gallery increases the flow of oil to the crank at high rpm. Two extra head stud bosses have been added. Blocks are CNC machined. Siamesed extra thick cyl walls. [.300" thick with 4.625" bore]. 4 bolt ductile main caps. Crank tunnel has clearance for a 4.5" stroke with steel rods. Dual sump bolt patterns. Bellhousing flange & rear mains are reinforced to resist cracks. 2 piece rear seal. Can be bored to 4.625”. Dart claim this block is good for 2000bhp.

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 were developed primarily for NASCAR type racing, but are suitable for all types of competition engines. H series bearings have a medium level of eccentricity, high crush, & conrod bearings have a hardened steel back & thin overlay. The chamfers are enlarged for greater crankshaft fillet clearance, & are made without flash plating for better seating. Mains have grooved upper halves and plain lower halves. Ideal for engines running in the medium to high RPM range. Contact pattern should be 2/3 to 3/4 of the bearing surfaces.

Performance Clevite "V series" CON ROD BEARING Sets

Performance Clevite "H series" MAIN BEARING Sets CHECK FOR FILLET CLEARANCE!

These bearings basically duplicate the old British Vandervell bearings and are suitable for all types of competition 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 greater crankshaft fillet clearance. The chief difference between the V series & other Clevite 77 Trimetal bearings 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 somewhat better comformability than lead-tin-copper overlay.

Clevite Performer Hydraulic Camshafts- “mild” Performance Good torque, performance gains in the low and mid range. Good idle. Can give power to 5500rpm

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 lifters full 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.

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.

Standard Hydraulic Lifters 1955-85 Gen 1 SBC, 1965-96 BBC Mk4 & 5

Hydraulic flat tappet

BY550-16

These lifters 'Bleed Down' below 3500 rpm, thereby reducing overlap and lift. In engines where noise is not an issue [eg: Stock Cars] a slightly wilder cam can be used, & yet still retain good power out of the corners. These lifters make a ticking noise. They are also a “high rev” lifter. Same fitting range as std lifters.

Sealed Power 'Hi-Rev' Hydraulic Lifters

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. BYHT817R Hydraulic flat tappet £62.28

Hydraulic Roller Lifters

Mechanical or solid lifters are most often used for Motor Sport applications. The oil to the rocker gear is restricted, so it is common to use rockers with needle roller bearing trunnions, that require less oil. Same fitment range as std lifters.

Competition Cams Solid Roller Lifters & Bars

These lifters are for use with hydraulic roller camshafts. There are two main types, standard as used in the original “OEM” engine, or “RETRO” for use in engines that never had a roller cam. Then there are standard, or “high rev”. For lifts over .570” or so, and rpm’s over 6000rpm, it may be safer to use the “high rev” lifters.

For years, Comp Cams Super Roller Lifters have set the standard for solid roller lifter technology. With todays radical cam lobe designs & increased rpm ranges, it takes a superior roller lifter to withstand the abuse. Now with EDM oil injection technology which ensures the bearing receives a constant flow of pressurized oil.

Competition Cams Roller Thrust Bearing The 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.

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 Bronze Distributor Gears

Cam Thrust Buttons & Lockwasher Cam 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.

Mr Gasket Advance & Retard Cam Bushes The offset bushes can be used to advance the cam for increased low-end torque and mid-range horsepower, or to reduce excessive low-end torque and increase top-end horsepower by retarding the cam. They can also be used to more accurately set the standard cam timing. Cam sprocket dowel pin hole must be drilled.

The standard cast iron gear is not compatible with a steel roller cam. Comp Cams gears are machined from AMPCO-45 extruded aluminium bronze with 5% nickel added. These gears feature a high strength tooth design that will resist wear even when a heavy duty oil pump is used. Carbon Ultra-Poly Composite gears have 300% increased durability over bronze gears, when used with a steel camshaft. Proven in NASCAR racing to give precise timing & extended durability.
