Remember in addition the block needs clearanced for the rods. You can purchase a short block 347 from several different suppliers including DSS and CHP and just add your top end and accessories

How much of the work are you planning on doing yourself and what type of numbers are you're looking for? If you shooting for 400hp or less na a stock bore factory block from Summit combined with a 3.4" stroked crank / rod / 4.00 piston combo will give you 342 ci. and should serve the purpose. The whole 347 thing kind of started with people taking their existing block, boring it out and putting a stroker together. Remember stroker "kits" are a fairly recent developement. 10 years ago you had to have your own crank custom made, fit up a mismatch of chevy, ford and mopar parts and make your own stroker. Today you can start with a virgin standard bore (4.00) block, standard bore 4.00 (different compression height) pistons and when the time comes to freshen things up, you just buy over size bore pistons, have a clean up bore done to the block, fresh bearings and your good to go. If you start out with a .030 overbore on your block to get the mystical 347 , when its time for a rebuild, you have to get a new block (because the maximum recomended bore on a stock block is .030). That's why my current engine is a 327 and not a 331
