buffer (bÅ­f'Ér) Chemistry A substance that prevents change in the acidity of a solution when an acid or base is added to the solution or when the solution is diluted.
These Ford Racing Performance Head Gaskets are specifically designed for use with cast iron or aluminum cylinder heads on a Ford 289, 302, 5.0L, or 351 Windsor V8 engine.
A major part of the displacement equation comes from the crankshaft, and thatâs where things get funky with the small-block Ford. There are many options for stroke and main journal diameter. Factory 302 engines use a small 2.248-inch journal size, where the production 351W uses a huge 3.000-inch journal.
