QUESTIONS ABOUT BUILDING MOTORS

im sure everyone is going to have their own opinion on this, so here's mine...
the completeness of the rebuild depends on your intended use(racing, daily, if you need another 100k out of it, etc..) and how it was taken care. i tore mine apart at 109k and all the internals were in great shape. you need to find a quality shop, first of all. speak to them and have the block cleand and magnufluxed, have them check the bores(if you are on a budget and dont need a bore, dont get one, it will save you the cost of a set of slugs) same thing with the crank, have its tolerances checked and if need be, have it turned down, if everything is fine, have it polished. alot of people consider having the rod bolts upgraded manditory and the same thing with balancing(the shop will need pistons, crank, rods and flexplate and possibly balancer) but these procedures add to the cost obviously. my opinion is that you can always bolt on new heads or a cam, etc...so do the short block right the first time. also, after all is said and done with the machining, sometimes a stroker short block isnt that much more(they start around 2grand), but if you feel everything is fine, a new set of rings and bearings are pretty damned cheap. sorry this is so long, but i hope it helps you out, nick
oh, just in case you didnt know, a 306 would be a .03 overbore on your current 4 inch bore, and would require a new set of pistons
