Well, I have an extra LT1 with about 90k miles on it. I was going to put it into my z28 that has about 150k miles on it but decided I'd just sell the LT1 and buy a LS1 and put that into the car instead and keep the LT1 in case I ever needed it(or for a project car).

So, by selling it and spending that cash on a LS1, what kind of mileage should I expect to be on the LS1? To sum it up, a 90k mile LT1 is equal to how many miles on a LS1?
