DESCRIPTION

350ci Bow Tie
Straight Nodular 4-bolt Main Bearing Cap

P/N 10185047
This block, which can be used for 302ci, 327ci, and 350ci engines, is the same as the cast iron Bow Tie bare block P/N 10051183, except that it has a “straight” nodular 4-bolt main bearing cap. It also features “siamesed” cylinder walls which could give it a maximum bore of 4.150”. It has a crankshaft diameter of 2.45” and the newer (1986 and later) one-piece type rear main seal. It replaces the older P/N 366287 4-bolt block, the difference being the one-piece rear seal rather than older 2-piece rear main seal. Block weight is 182 lbs.
