if free or very cheap ? if heads are good crank and rods .timming cover .tin .head bolts. oil pump drives are HD .i have used the main caps to turn a 454 blocks from two bolt to four bolt main but is alot of work and a line bore . if you want a 427 short deck 9.800 block as the crank is a 3.760 crank so the crank can be used to build a 396 up to a 427 with the right bore size 9.800 deck block .that block is 10.200 and is not the hot deal for any hp build . the 9.800 deck fits better in most cars and a 9.800 deck block
