It is a factory, heavy truck motor. Cast iron crank. Strictly a low rpm workhorse. It is based in the latest series of big blocks, with their cooling and oiling differences, one piece rear main seal. As built, there is nothing hi-performance about it. Heads are small port truck.. But, those glorious cubic inches! Add some hot rod parts and you should have a real stump puller..
