400 big block

I am building a 451 also,possibly a 470 depending on the condition of the crank. I now have a set of KB280 pistons/pins. Very lite,weight 520 grams or so. Combine it with the excellent 440 crank/rods and you have the ultimate budget 451 with the reliabilty of a 440!

I see 451 engined mopars on pinks all the time. Many of them make it to the final 8.

It' makes an awesome bracket motor in a lightweight car.Im hoping to get my Darts weight under 3000.


I wonder about that cold weather block.A good chance many canadian and northern states cars came with one.
