440

[Schimms15]

There's two used 440 on craigslist. If I went to look at them what should I look for. One is 300 the other 1200

I'd say it depends on what your plans are? If you plan on rebuilding it anyway ( core) then go for the cheapest option. If it's a running engine your after and don't have a big budjet.... check compression, look at head casting #'s check the oil ( clean/dirty)

If not running, you need to pull the heads and check bore, also check lifter valley for cracks from a hard freeze.  CDEFG blocks are for the most part, steel forged crank engines.  Before pulling heads, see if the engine spins over by hand first. Take an 1 1/4 wrench with you or socket extention and ratchet.   To rebuild a 440 back to fresh is around 12-1500 bucks. As you step up into performance and around 3k for start

When you say rebuild what are you including?

If you plan on building a motor (pistons, alluminum heads, forged crank, stroker kit etc.) and all your worried about is the block then go cheap (price not material). If you are just looking for a running motor then there is more to it like Brads70 said.

 to do block prep
re ring, bearings, turn crank,  valve job, cam n lifters, timing chain, oil pump, clean all covers and gasket set.  This is a basic keep it simple rebuild like this. Useing the block dates above helps with the compression, then finding 66-67 date heads will give you an increase in compression, but and about 325 more to the cost of installing bigger valves, hardened exhaust seats and a better valve spring set up.
