1973 440

I have came across a complete 440 locally, for 300 dollars.

I do want to put a big block in a car down the road...

Can someone give me some info on the 440's?

I would assume the 71 and earlier motors had higher compression, and perhaps better cranks and pistons and rods?? Maybe even better heads?

The motor is said to be from 1973...

Is it worth getting?

Thanks,

Shane
