  • Sizes in reference to Deck Height, Cylinder Bore, Wall Thickness, etc, listed in these instructions are Nominal. This Block must be professionally finish machined.
  • Due to a vast difference of opinion among professional builders regarding specifications and procedures, all blocks, when purchased bare, are finished within factory +/- tolerances. Tighter than factory or OE specs when applicable.
  • Cam bearing OD should be de-burred before installation.
  • When initially removing main caps, the caps & block should be de-burred before reinstalling; this will insure that correct main size is maintained.
  • This Block should be assembled by experienced, professional engine builders. Many parameters such as Cylinder Bores will need additional, professional machine work.
  • Many pistons are oversized, and cylinder bore must be honed to correct skirt clearance. Very few aftermarket components are drop ins to any engine block, without additional checking/machining.
  • Aeroflow Performance engine blocks are the ideal starting point for any street performance build that demands quality and precision at a reasonable price. Why start your engine build with a worn-out production block from decades ago that needs hours of machine work. When you can start with a new heavy-duty cast iron engine block that is a semi-finished bare engine block that requires very little machining to match your internal components. These brand-new aftermarket engine blocks are cast from premium high-strength Class 32B iron. It features Siamese cylinder bores and splayed billet steel four-bolt main caps with priority main oiling system which direct oil straight to the main bearings. The extra thick standard deck height ensures a reliable head gasket seal as well as allowing the use of off the shelf standard components such as camshaft, timing chain, oil pump/pan and oil filter etc. You can rest assured that these Aeroflow engine blocks have a great foundation for your next engine build.
