In response to swoop- no disrespect- but- the 'industrial' engines we have today are mostly modified auto engines. I had a customer with a 6 series Toyota which had a Chevy 4 cyl engine. I forget the nomenclature for the engine but it sounded real new & high tech. I had to replace the head gasket & it was back ordered from every forklift channel I tried. I went to my local NAPA dealer & after some research found out this engine was installed in 1969 Chevy panel trucks along with '69 Novas. So much for 'latest & greatest'.

On a side note- from the dealer there was a choice of head bolts- standard or torque to yield- although there was no choice of head gasket- only one part # for that. I thought that was interesting. Opted for the standard bolts & never had a problem from that point forward
