Didn't get what I wanted and paid for! Paper work reflected different parts then I wanted, Very bad quality, engine had very low miles under 2k, low oil pressure 17 lbs at idle, builder said that was good enough, safety equipment shuts engine off less than 20 lbs, u would think they would know that,knocking at the main bearing and rocker arm noise, pulled it and returned under warranty it was disassembled in front of me, we<<seen damage of rear main bearing, crank man said something went thru it and the builder was pulling chunks of gasket from oil pump screen, which they cleaned along with other major parts, picked it up few days later, paper work stated there was nothing wrong with it, checked all clearances, heads so forth, how can that be, seen the damaged bearing my self along with them, started up and still have noise, valves springs installled incorrect,paid good money for junk junk, junk, suggest you shop around,
