You should always check the year of your engine before torquing any bolts.

It was replaced by the 4. This was one of the least talked about yet most transformative and comprehensive performance and durability upgrades of its time. And, if you are talking about the torque output of the motor, well, that depends upon how it is built, and, with what parts. The exact displacement is 349. Overheating and damage are likely if head gaskets or heads without 'steam' holes are used on a 400 block.

It offers the performance of more expensive heads, at a much lower cost. The oil-fill location was moved from a tube on the front of the intake manifold to a cap on the left- or right-side valve cover, depending upon the application. We have the L-82 to thank for this not being the case — in its day the L-82 was a pretty amazing performance motor. When the journal size increased to the standard large-journal size, the crankshaft for the 302 was specially built of -hardened forged 1053-steel and fitted with a high- 8 in 203.
