The "short block" is apparently identical on all those engines, SOHC (trucks, minivans etc), dohc Stealth & VR4 or twin turbo VR4/stealth! I sold mine with almost 500,000 miles, burning NO oil, running perfect (after 2 trans rebuilds from towing a 580 C Case backhoe and large 29 foot boats (STAMAS Family Fisherman) 6500+ lbs on trailer...its ENTIRE life!! Was gonna turbo mine, but didn't find management I could tune(and trust)!
UNREAL capacity and "overhead" built in these trucks...
