Stroker with stock deck height and bore can either be 331 or 347. Why wouldn't you want to bore it? lack of tools?

Your going to have to get new pistons anyway for the right stroker.

Well you did say it's getting up there in miles so even a standard rebuild might call for boring. Maybe your shop teacher can get a local machine shop to donate some work. Think you can still get stroker kits with the standard bore pistons but why, cost would be the same. Stock bore but stroked is actually 327 CI or 342 CI. I would love to tell people that I was running a 327 Ford motor!

Without boring it is possible to get a 327 or a 342.

That said...
1. If your car is "getting up in miles" it will need to be bored, if for no other reason than to give new rings a fresh surface to work themselves into.
2. There is no stroker that you can use your current rods and pistons. You will need longer rods and pistons with a shorter compression distance.

Dave is right, you can use a stock 4.000 bore but add in the 3.250 stroke for a 327 or a 3.400 stroke for a 342. That's about the limit for a stock 5.0 block.

How many miles does it have? If it's really high, you might need to get it bored. If they're out of round, it won't have a good ring seal.

But you'd need new pistons for sure because stock pistons won't work with a stroker kit, they'll be coming out of the tops of the bores and crashing into the heads so you can't get out of that. You'll need pistons that have the wrist pin relocated to compensate for the longer stroke and stock pistons won't work.

well it has 175,000 miles. that being said its a great running car and still holds great compression. i dont know a whole lot about boring. im just worried its gonna cut my fuel economy in half. maybe you guys can help answer...???

if your gonna do stoker you need new pistons for clearance issues and why risk having scored up cylinder walls that wont hold compressions because rings cant seat well? I mean you have the block torn all the way down why not just bore out to .030 over and have a clean cylinder walls for your rings to seal up well? If you wanna save a few extra bucks you will be paying even more in the long run if something goes wrong. Something I learned while working on engines is that you never wanna HOPE it will work, you gotta make SURE its gona work..

Lol, relatively good fuel economy can still be achieved with a performance engine. Its a trade off though, to make more power you have to burn more............GAS!

... A 5.0 block can't be taken to a 427.

I don't think any 8.2" deck SBF can be taken to a 427....

But what do I know

If It runs great, holds compression, and you're on a budget leave it alone.

Stroking will cost you more that boring fuel consumption wise. The absolute maximum a production block can be bored is .060", while the maximum you can stroke it .400". Do the math.
