There is no problems what so ever with this block it is absolutly in perfect condition with all brand new parts with 0 miles on them. You would need a Head/ tranny basicly to finish this and have a amazing single cam high compression motor. I am making a road racing ef for nasa events/ honda challange (h1) and didnt understand the rules fully then after purchasing this stuff I realized for (h1) that I need a completely stock OEM d16a6 or a b series/k series entirely consisting of OEM parts depending on what level I race at so Basicly I need this stuff gone asap and thats why I am selling it for so cheap. My loss your GAIN! Let me know guys, Thanks! Josh
