All: I cannot speak to the 413 engines. I started my career at Chryslers in the old Windsor Engine Plant, in the summer of 1971. I was there for the start of the 360 engines. Windsor machined all of the raw castings for those engines, including blocks, cranks, cams, pistons, rods and both intake and exhaust manifolds. As the tooling wore down during the machining process, the tolerances varied. I don’t mean out of spec; but ranged from the allowed minimum to maximum. When it came to assembling the engines the components that went into severe duty engines, hi-po, police interceptor, 360 truck engines etc. all received parts that were as close to the base line specs as possible. I would hope that all of the old performance engines received similar care. 300ly bill From: Chrysler300@xxxxxxxxxxxxxxx <Chrysler300@xxxxxxxxxxxxxxx> On Behalf Of Val Jeffers edward1108@xxxxxxxxx [Chrysler300] Sent: April 18, 2019 9:06 AM To: Chrysler 300 List <chrysler300@xxxxxxxxxxxxxxx> Subject: [Chrysler300] G Engine Greetings all, There was some discussion regarding the above several months ago and I want to make sure I am clear. When the engine is being assembled and they are aware it is going in a G they simply stamped the H on the top of the engine boss ? So if that be the case and there is no difference in the pistons or heads then the ram manifolds must be the main thing right ?
