I ran across a 377 buildup ( 400 cu.in block bored .30 with 350 crank) but didnt get all the info.. I know theyre hi-rev engines..
What exactly do I have to do to assemble one ? Are forged parts necessery ?

Thx 4 the info (if there is any lol)

 

Forged pistons should be used but lower cost pistons will work also. all the fasteners should be good aftermarket like ARP etc.

To put a 350 crank into a 400 block special bearing spacers are required since the mains in the 400 block are larger.

These engines are designed for high rpm HP but with only the stroke of a 350, don't produce as much low end torque as a 400. A typical race 377 starts building power above 4000 rpm. A street engine usually tops out around 5000 rpm.

The 377 makes a good race engine for drag or oval track but I wouldn't suggest one for use on the street. Build a 350, 383 or 400 instead.
