400 BB build

A word about pistons. Best to go forged if you throw turbo's at it. The hypers will hold up to NOS and the manufacturers claim at KB is that they will hold up to turbo's and nos if the right engine management is in place.

Im building a 451 for my Dart and so far have a good start. The 451 is the most budget minded bb stroker as you can tecnically use all factory parts. That means stock rods,cranks,bearings etc can be used. It fits good in an A body as it is a B block and factory C body exhaust manifolds can be used. Im going with headers myself but it isnt hard to make 550 h.p with exhaust manifolds on this motor. 550 is childsplay for a 451!

Some of the 400 blocks are good for 800 h.p. The factory forged crank will live just fine at 650 h.p. 440 source makes some kits for this stroker as reasonable prices. K1 makes a real nice cranky shaft for this motor !

451 is a torquey quick revving big block!:burnout:
