Looks like I'm going to have to replace/rebuild my tired, oil-thirsty 440.

Option A: Have the bottom end redone locally (and have them put in a hotter-than-stock cam) and put on a set of those near-stock cast iron Aero heads. I want to re-use the dual-quad setup I have and put on a pair of HP exhaust manifolds I have. This would run me probably about $2500-$3000. or so.

Option B: Get a remanufactured long block from this place...

...ask for a mild performance upgrade, throw my stuff on it and call it a day for about a grand less.

I would love to have a 600hp beast, but the car and my wallet aren't up to it. At this point, I am just looking for a reliable driver...

Any opinions on which might be the best option?

Thanks.

Also, what would be a good cam grind to get a nice, lopey-ish idle but good drivability.
