If the 400 is a 481988 block it's an excellent foundation for a high performance rebuild- get some early 72cc D-port heads, a decent cam (280 dur/480 lift or better) and you're making at least 350 hp- 400hp with all of the usual power adders and tuning.

keep it ,the 74's where the last of the good castings,I have paid $400 just for a bare block , the lower webs are thicker so they are less prone to cracking
