Dart Race Series Aluminum Small Block Chevy Blocks

We created all new tooling and added superior new features like central oil cross-overs and extended cylinder barrels. Deck heights from 8.850 in. to 9.500 in. are available. Dart’s Aluminum small block is light, strong, and affordable.
Deck heights from 8.850” to 9.500” provide maximum versatility. Cylinder barreLS2 are extended at the bottom for better piston support with long strokes; Raised camshaft (+.391”) provides more clearance for stroker cranks and eliminates need for fragile small base circle cams. Option for .434” raised cam; Siamesed 4.000” or 4.125” cylinders can be safely bored to 4.165”. Ductile Iron sleeves and extra thick walLS2 produce excellent ring seal; Requires use of remote oil filter. No provision for block mounted filters; Relocated oil pan raiLS2 are spread .400” per side (.800” wider than stock). Oil pan bolt holes are relocated in line with main caps; Big block camshaft bearings allow the use of cams with larger base circle diameter to improve strength and reduce twisting with cam driven pumps; Rear external oil inlets, with crossovers and restrictor provisions located centrally in the valley to simplify plumbing with external pump; Parts kit included (PN 32000012 )
