You can get an overhaul kit from Engine Parts Warehouse Inc. for about $220 which includes 4.030" flat top cast pistons giving a C.R. of about 9:1, but you will still need a cam, block cleaning and boring, heads rebuilt, probably a dual plane intake, rebuilt distributor and headers. I am trying to do it for $2000 and it is close so far without the headers or distributor AND then I only have cast pistons. Oh yes, I added a set of new rods for $90. I enjoy knowing what is in my engine, but at the risk of screwing up something so maybe you should look at a Goodwrench rebuilt crate moter for about $1400, but then the warrenty is void if you change the cam. I would say that a 350 can be built for $2500 so take a look at crate motors before you start.
