So I decided to start my first build, and have bought a mint 440 big block with a 727 on it. It runs pretty good and everything. What’s the first thing I should start with?

Ah, paint it?

Seriously, things like a compression test, std refresh would be a good idea. Where did it come from (type of car/truck), year and what do you want to do with it?
You'll need different things for 1/4 mile, circle track, daily driver or a combination. What's it going into?

Ya gotta give us more info.

Well it’s out of a 2500 truck, it’s a 70 440 long block with an edlbrock intake. That’s just about everything I know about it.

 

Hayden -

And what do you want to do with it???

If it's never been rebuilt, it's due.
The parts you put it depend on it's purpose.

Ditto on the tranny.
