No, the heads on a Ford 289 motor are not reversible. The cylinder heads are designed to be installed in a specific orientation to match the intake and exhaust ports on the engine block. Reversing the heads would result in misalignment of the ports and poor engine performance.
number one cylinder is the left front of the engine, sitting in the driver's seat
With stock gearing 62-65 mph
The atomic number is determined by the number of protons in an atom. Therefore, if an atom has 65 protons, its atomic number is 65.
The additive inverse of a number is the value that, when added to the original number, results in zero. For the number 65, the additive inverse is -65, since 65 + (-65) = 0.
65 - x

Piston engine horsepower of any kind cannot be calculated by engine displacement alone.Horsepower is a broad term which simply denotes 745.7 Watts of power output by any given mechanical or electrical device.First off, there are three (3) types of horsepower involved in a piston engine, they are:1.) Indicated Horsepower (IHP).2.) Brake Horsepower (BHP).3.) Friction Horsepower (FHP).Indicated Horsepower = Theoretical horsepower of a piston engine at a given RPM.Brake Horsepower = Available useful horsepower output of a piston engine's crankshaft while at a given RPM and Torque.Friction Horsepower = Horsepower needed to keep a piston engine running at a given RPM.Indicated Horsepower = Brake Horsepower + Friction Horsepower.For all intents and purposes the Brake Horsepower (BHP) of a piston engine is the useful horsepower which should be used to measure a piston engine's power output. BHP is derived by the combined measurements of Ft-Lbs Torque and RPM at the crankshaft.To answer this question correctly using just engine displacement alone is not possible. More engine data is requiredTherefore, I will post an example of an existing automotive gasoline piston engine and demonstrate how to calculate its Brake Horsepower.Most if not all automobile piston engines are based on a 4-stroke piston duty cycle. This means that one duty cycle of each cylinder's piston is based on: Intake, Compression, Power & Exhaust piston strokes.The significance of mentioning this is that the combustion powerstrokes per minute (N) are exactly half of the engine's RPM in regards to a 4-stroke piston engine.Take for instance a Chrysler Mopar 2.5 Liter In-Line 4-Cylinder, 4-Stroke, Gasoline Automotive Piston Engine with the following specifications:Engine: Chrysler Mopar / In-Line 4-Cylinder / 4-Stroke / GasolineDisplacement: 2.5 Liters (2,500 cc)Piston Bore Diameter: 3.44 inchesPiston Stroke Length: 4.09 inchesMaximum Torque Output: 135 Foot-Lbs @ 2,800 RPMCompression Ratio: 8.9:1The most accurate method to calculate BHP based on Maximum Torque output on automotive piston engines is the following:BMEP - 4-stroke = [(150.8 x Torque) / (CID)]BHP = [(BMEP x L x A x N x K) / (33,000)]BMEP = Brake Mean Effective Internal Cylinder Pressure in PSI per powerstroke.Torque = Maximum torque = 135 Ft-Lbs @ 2,800 RPMCID = Total Cubic Inch Displacement = [(2,500 cc / 16.387)] = 152.56 cu. in.L = Piston stroke in feet = [(4.09 / 12)] = 0.341 feet.A = Piston head area in sq. in. = [(3.14159 x (3.44 / 2)^2] = 9.29 sq. in.N = Number of powerstrokes per minute = 4-stroke = [(2,800 / 2)] = 1,400 p/m.K = Number of Cylinders = 4.BMEP - 4-stroke = [(150.8 x 135) / (152.56)] = 133.44 PSI.BHP = [(133.44 x 0.341 x 9.29 x 1,400 x 4) / (33,000)] = 71.7 BHP.So this particular automotive gasoline piston engine will develop a Brake Horsepower of 71.7 BHP while at its Maximum Torque RPM of 2,800.[65 / 234]^3 x [Vehicle Weight in Lbs] = 71.70.0214334705 x [W] = 71.7W = [(71.7) / (0.0214334705)] = 3,345.24 Lbs Vehicle WeightIf this engine maintained a steady 2,800 RPM with a Brake Horsepower output of 71.7 BHP it will keep a 3,345.24 Lbs vehicle moving at a steady cruise speed of 65 MPH.Many different 2.5 Liter gasoline-powered, 4-stroke, 4-cylinder automotive piston engines all operating at the same RPM can have completely different BHP & Torque outputs.Useful horsepower (BHP) of a piston engine is primarily a function RPM and Torque and cannot be calculated by engine displacement alone.---------------------------------------End Wiki Answer--------------------------------------
Number 65 is Drifloon.
No 65 is not prime since it has factors of 1 and 65 or 1*65=65 and 5 and 13 or 5*13=65. Prime numbers have only 1 and that number as its factors.
Wow what a coincidence I just bought a 65 mustang in Australia with this engine number, could it be the same engine ?? I would be interested to here from you. inoxpa@bigpond.com
