Okay – let’s get to work and build a 388 (bore x bore x stroke x number of cylinders x .7854)
You told us that the block is .060 over so you’ll need 4.060” pistons. White Performance Machine has an ebay special for a balanced assembly including crank, pistons, rings, connecting rods, flex plate, damper, and big bearings for $769. This assumes a 3.75” stroke so you need to make sure that your block has been machined for such.

Get a new oil pump and pickup that already welded to the pump – another $70

Summit sells their aluminum heads for $995 -
http://www.summitracing.com/parts/sum-162109/overview/ I’d buy new bolts for another $80 and a good gasket set will add another $75 or so.
Cam and lifters are all over the place – however, as mentioned above a roller retrofit is a good idea. Summit sells a COMP Cams retrofit kit with the cam, lifters, pushrods, springs, timing set and all the accoutrements for $900 -

So now we have the major long-block pieces and we’re at $2,900, plus additional machine shop charges to relieve for a 3.75 stroke, deck the surfaces, and install cam bearings – probably +/- $350 so we’re at $3,250.
Intake – Edelbrock 7104 Performer RPM is a great choice with a 750 Q-Jet (electric choke). This combo will be about $525.
HEI distributor - $100
All the “other little things” i.e, fasteners, spark plugs and wires, water pump, etc. will be +/- $500 and that assumes that you have all sheet metal, (pan, valve covers, front cover) the tools you’ll need as well an engine stand and a nice, warm, well lit place to build this engine.
Soooo. We’re looking at about $4,400 smackers – still want to build it yourself? If so, you may want to search this site for small block build threads as there have been a lot of them and you’ll find all kinds of gems concerning cleaning the block, painting the block, assembly lubes, keeping it clean, etc., etc., etc…
Let us know what you decide!
Best,
