The Big M Sportsman block gives you the versatility to build a wide variety of engine combinations. A true priority main oiling system oils the main bearings before the lifters for extra reliability.

Features:

  • 9.800" deck height.
  • 4.600" bore size with siamesed extra thick cylinder walls to resist cracking and improve ring seal (minimum .300" thick with 4.625" bore).
  • Uses +.300" tall Gen VI style lifters.
  • Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to equalize temperatures.
  • 4 bolt ductile iron main caps have splayed outer bolts for extra strength.
  • True priority main oil system lubricates the main bearings before the lifters. Our stepped main oil gallery (9/16" to 1/2" to 7/16") increases the flow of oil to the crank at high rpm, and our front oil crossover eliminates internal oil leaks around the distributor shaft.
  • Oil filter pad is drilled and tapped for an external oil pump.
  • Lifter valley head stud bosses prevent blown head gaskets.
  • Rear main cap uses standard oil pump and two piece seal - no adapter required!
  • Mechanical fuel pump boss, clutch linkage mounts, and side and front motor mounts simplify installation in any chassis.
  • Dual oil pan bolt patterns fit standard and notched oil pans.
  • Coated cam bearings, freeze plugs and dowels are NOT included.

Hamilton targets winning streak

Thu, 19 Jun 2014

LEWIS HAMILTON knows he needs another run of four successive victories if he is to overhaul team-mate Nico Rosberg in the race for this year's Formula One world title. It is a feat Hamilton managed earlier this campaign after Mercedes rival Rosberg won the season-opening grand prix in Australia where the Briton retired. Hamilton then triumphed in Malaysia, Bahrain, China and Spain, clawing back the 25-point deficit, with Rosberg forced to settle for the runner-up spot on each occasion.

Driven: Nissan Juke

Wed, 25 Aug 2010

Nowhere is the fragmentation of established market segments more evident than when thumbing through Nissan's current brochures. The new Nissan Juke, the smallest and most extreme member of Nissan's crossover range, is pitched as an 'urban proof' alternative to more conventional superminis. We took it to the streets to see how Nissan's scattershot small car strategy – which sees a range of four models occupying a similar space physically and fiscally – plays out.
