I just bought a pair of Arias heads off of ebay for $200. I have no clue about them and the description didn't help at all. I was wondering if anyone here knows anything about them. He said they are the "Wide Head"? I know Arias has heads that go on the BBC, but these heads look like they won't go onto a stock configuration. I saw a picture of an 8.3L Arias block and the head bolts where the same as the heads, four bolt pattern. Can anyone point me in the right direction? Thanks, Randy
Be careful if they were used on a alchohol burning engine. Seen many cheap aluminum Hemi heads at swapmeets that were porous from the alchohol/methanol.
Methanol is used on a limited basis to fuel internal combustion engines. Pure methanol is required by rule to be used in Champcars, Monster Trucks, USAC sprint cars (as well as midgets, modifieds, etc.), and other dirt track series such as World of Outlaws, and Motorcycle Speedway. Methanol is also used, as the primary fuel ingredient since the late 1940s, in the powerplants for radio control, control line and free flight airplanes (as methanol is required in the "glow-plug" engines that primarily power them), cars and trucks, from such an engine's use of a platinum filament glow plug being able to ignite the methanol vapor through a catalytic reaction. Drag racers and mud racers also use methanol as their primary fuel source, as well as heavily modified Tractor Pullers. Methanol is required with a supercharged engine in a Top Alcohol Dragster and, until the end of the 2006 season, all vehicles in the Indianapolis 500 had to run methanol. Mud racers have mixed methanol with gasoline and nitrous oxide to produce more power than gasoline and nitrous oxide alone. One of the potential drawbacks of using high concentrations of methanol (and other alcohols like ethanol) in fuel is its corrosivity to some metals, particularly aluminium. Methanol, although a weak acid, attacks the oxide coating that normally protects the aluminium from corrosion: 6 CH3OH + Al2O3 → 2 Al(OCH3)3 + 3 H2O The resulting methoxide salts are soluble in methanol, resulting in a clean aluminium surface, which is readily oxidized by dissolved oxygen. Also the methanol can act as an oxidizer: 6 CH3OH + 2 Al → 2 Al(OCH3)3 + 3 H2 This reciprocal process effectively fuels corrosion until either the metal is eaten away or the concentration of CH3OH is negligible. Concerns with methanol's corrosivity have been addressed by using methanol compatible materials, and fuel additives that serve as corrosion inhibitors. When produced from wood or other organic materials, the resulting organic methanol (bioalcohol) has been suggested as renewable alternative to petroleum-based hydrocarbons. Low levels of methanol can be used in existing vehicles, with the use of proper cosolvents and corrosion inhibitors. The European Fuel Quality Directive allows up to 3% methanol with an equal amount of cosolvent to be blending in gasoline sold in Europe. Today, China uses more than one billion gallons of methanol per year as a transportation fuel in both low level blends used in existing vehicles, and as high level blends in vehicles designed to accommodate the use of methanol fuels.
