This 12 3/4" Small Block Chevrolet Flywheel is for 1986 and up. Standard weight flywheel for one-piece crankshaft seal.

Note: Torque converters for TH350 and TH400 transmissions are produced with both 10.75” and 11.50” diameter converter bolt patterns. To identify the correct pattern, measure from the converter center to an attaching bold hole and then multiply this dimension by 2.

Technical Notes: Flywheels, in engines before 1986 us a two-piece rear seal. The bolt circle on pre-1986 production crankshafts is 3.58” in diameter. For 1986 and later production crankshafts the bolt circle is 3.00”. If your engine has a crankshaft with a one-piece rear seal, you must use a flywheel (or flexplate) with a 3.00” bolt pattern and a counterweighted flywheel for proper engine balance.
