Anyone done the 318 to 390 stroker build ?

I need more power !

Currently running a 318, .030 over, 340 cam, edelbrock performer intake 600cfm elelbrock carb, early 340 exhaust manifolds. Runs good but I want more...

Thinking of doing the 390 stroker, just wondering if anyone has done it,, did you buy a kit or shop for the parts individually ?

Also wondering,,,,Since I had the engine bored .030 over and assembled several years ago, its only been driven around 5000 miles...
Would I have to get additional machine work done on the cylinder bores to take the new pistons,,, or should my bores be ok as long as I get .030 over pistons ?

Next, how much will it cost to put together the parts for shortblock.
I'm already planning on looking for J or X heads cause i'm pretty sure the 318 heads would not be the best choice for a 390.

OR, Option 2
Pick up a used but running 360 and do a basic rebuild, then add cam, better heads.. etc.

I dont have 4 or 5 grand to spend on an engine so I need the most bang for the buck.. or lack of bucks... lol
