I monitor the "List" each day looking for technical questions regarding the Eagle 540 engine. When I saw the venomous critique of the Eagle 540 I wondered whether the writer (Carlson) was describing the same engine. Simply defined, the Eagle 540 engine is a 540 CID 500 hp V-8, inline 2 valve per cylinder, with shaft rocker arm assemblies. It's tuned induction features equal length equal spaced intake ports which open to a common plenum beneath the port runners. The lower end bearings are larger much larger than a 454 or 502 BB Chevrolet as are the connecting rods and wrist pins. The bore is 4.500" and the stroke is 4.250". American Engine owns its own casting patterns, forging dies and tooling to generate this "original design" engine. Block, heads, crankshaft, connecting rods, induction manifold, exhaust manifolds are not interchangeable with Ford, Chevrolet or Chrysler. Block and heads are aluminum, induction, rockerbox covers, sump, and PSRU are cast magnesium. The firing order is entirely different than the Chevrolet. Testing was first done using a DTS dynomometer and further testing was done in our computer enhanced test cell with PSRU, propeller, and all systems fully funtional. Accompanying this was structural materials properties analysis. Extensive flight testing is scheduled wihin the month now that pre-production first phase ground testing has been completed. The airframe integration package designed by former Boeing engineer Curtis Longo allows for increased useful load and stability in flight improvements. This is not to be considered a sales pitch or an endorsement of the Eagle 540 engine, but rather a technical description to correct any misconceptions and other erroneous data submitted to this forum.
