I like mine alot, I built it at home, and it does pretty much what I wanted it to do.

PM me if you have any kind of specific questions you don't want to post, but it's all be covered pretty well.

The way I look at it is:
If you like 440s, then you will love the 451 low deck.

It acts similar to a bored out 440 in some ways, but seems to like RPM maybe slightly little more...it is smaller on the outside...gives more room for big headers, and more room for taller intake manifolds.

No better use for an old steel 440 crank with trashed mains
