349 CI on the cheap
I'm not sure where my post went. i wrote it a while ago, it lokoed like it went up...Anyway..
I finally got to the book I wanted. What I would do is go with a flat top 307 Chevy piston, .040 over. Specs end up like this: 3.935 bore, 3.58 stroke, 6.123 rod, yeilds .015 down in the hole on a 9.6 deck. I have found dished and flat tops w/4 valve releifs in the few tries at searching. $122 plus shipping w/rings off ebag. The pistons would need the pin bores cut for pin retainers. Most blocks are taller than 9.6 to start, but it gives a little wiggle room if needed. The valve releifs are not placed right, but I think running them .015 down, and runnnign Magnum or 302 type heads with a mild to medium cam would make things fine anyway. The rods would need the bushings swapped to ge tthe chevy pin size of .927 from mopar's .984. But that's no big deal, part of re-doing rods anyway. All totalled, it would end up aounr $1300 plus parts, for bore, hone, sq deck, redo rods, modify pistons, turn crank, and balance. I'm sure the complete engine could be done for under $2500 using swap meet or ebag stuff, and buying a set of new/done Magnums. Assembling yourself too. That makes a 10ish:1 static 348 with good qeunch, modern heads, and decent street manners. It would be decent for mild truck or street/cruiser. Redline would be 5500. That's how I'd do it. I had a 318 with some chevy pistons years ago, and they worked fine.
