When did the GMC 366 gasoline engine come out?

General Motors Company introduced the 366 gasoline engine beginning in the 1960s and continued production until the mid-1990s. The 366, which is considered a tall deck motor because of the elevated shape and design, has a small bore and long stroke, making it a powerful workhorse that doesn’t produce particularly high rpm.

Is the 366 cylinder bore smaller than the gasket?

Tall deck engines are no less likely to incur headgasket failure due to this spacing than a standard engine. In the photo can be seen how much smaller the 366 cylinder bore is than the gasket which sits on it (and yes, this is the first disassembly of a factory engine).

What are the gaskets on a 1972 366t engine?

As can be seen below, this set of factory heads off of a 1972 366T engine is a standard oval port casting. Visual indication of standard head use: as can be seen below, the head gaskets on this factory 366 cubic inch engine used standard size gaskets.

Are there valve springs on a 1972 366t engine?

The valve springs and rocker arms are not anything special, as these engines were not made to turn high revolutions per minute, instead specializing in low end grunt power. As can be seen below, this set of factory heads off of a 1972 366T engine is a standard oval port casting.
