What is the cost of converting a 350 to the four-and-an-eighth bore 391

What's the CR of that engine?

Finally, I don't care about running 10s, but I do care about getting 60,000 miles out of the engine with it running nearly as good at the end of that 60,000 miles as it did after the break-in. Can I do that?
For complete rotating short block done ready for install $9500
New pistons,rings,rods,etc.
You need to supply a good short block/crank.

Compression is your choice 9.5-1 thru 13.0-1

The way this is done the sleeves are thicker and stronger then open deck 4" sleeves.
One of these already have 10-15k miles on them with alot of drag time
alot of Chicago traffic and has run 10.40's @ 133 this car runs just fine.

So if you won't drive it as hard as the above car then i would not worry about reliability.
