No new internal parts. Was out of a wrecked Silverado with 66k miles on it.

Bill some do but most major car makers do not have this as a factory option. Just one of those things that I won't do again...lol Plent more motor swaps going forward. The LS conversion is just too easy and perfect for all applications.

Awesome! Great news. Look forward to seeing her on the trail.

PS, you can do an oil sample before/during your first oil change to "see" whats going on. They work and will show trends if you use them often. About $20 a pop at the Cat dealer.

Sweet! For a well broken in motor, running out of oil hopefully won't be a deal breaker. She sure seems to run well

Cheers!

Yeah, I'm really happy to hear that it was a worn-in motor- the damage would likely be far less than if he'd run a rebuild on no oil.

JP- glad to see it's back in action.

The plan was to go single exhaust. Have the passenger side manifold drop down and wrap around the front of the oil pan. It would then Y into the drivers side and run back to a muffler and then exit out the side. I am reusing my flowmaster muffler and asked to have a flange added after the Y so when the exhaust shop is done I can drop it and wrap it. The less heat coming off it the better.

Exhaust wrap will make it run a bit hotter temp wise. The wrap, as used for power increases, is designed to raise the output temp of the combustion process by insulating heat loss from your headers and lower the intake temperature by shielding heat from the intake. Thermodynamically speaking, the greater the difference between input temp an output temp of such a system the greater the system efficiency the greater the performance. But it's at the cost of higher running temps.

Sorry for the earful

Cheers!

Heat I can deal with, with this motor. It runs more efficiently and cooler than any other motor I have seen. Plus I'm running dual fans and a four core radiator. Got her back from the exhaust shop yesterday and man am I Happy, Happy, Happy. Not a HUGE fan of the exit strategy but I did give the guy the green light to do what he wanted in certain areas and did not have a good game plan for the exit. We will see what happens on the rocks. But man the thing runs great, seems to be no issues I have seen yet. Still needs some serious work before wheeling next weekend. Keeping my fingers crossed it all comes together in time.
