Spare engine is a good idea if you have a place to store it. I seen a engine out of a 03' go for $1300 on ebay about 2 months ago. It probably didn't have more than 25K on it.Q45tech wrote:You must pull the engine to an engine stand then remove the heads then the pistons..............much much longer than a simple engine swap.If you pull the pistons might as well change the rod bearings [supercharged loads] at the same time.
Who will be as precise as you might want to pay for is the question?
Just have a prebuilt spare engine ready at all times and swap periodically.
Finally these 3.5 will be plentiful due to US sales [wrecks] now.
