Changing oil is one of the cheapest things you can do to prolong your engine life, especially with a high performance engine like the LT4.
I changed mine at 500 miles, and added the dimple magnetic drain plug. The oil looked new, but good piece of mind.
Changed it again at 1500 miles, a bit dirty this time.
Will change again at 3000 miles.
This hot rod will be in my family a long time, so overkill is fine with me.
Added mid America motor sports donut magnet to the oil filter too.
Changed the rear diff fluid at 1500 miles, grey and nasty with quite a bit of fine metal sludge on the magnetic plugs, will change it again at 3000 miles.
Love this forum, and the info that’s shared.
I wouldn’t have found out about the performance break in procedures with out you guys. And a good excuse to go,out and wrench on the car a bit
