5.3 Rebuild Cost

[RichardP]

So I have been looking around and $2500 seems to be the number. It's not bad just making sure I am in the ball park. I am not a mechanic so some of this will have to be subbed out.

The gen 3 I am looking at still has the 305tpi so it will need the 5.3 to be competitive. Just trying to get a ballpark number on this. Thanks.

A well used stock 5.3 still makes plenty of power. No real need to rebuild it. A 100K mile stock motor that has never been opened up is less likely to blow up than a fresh rebuild...

assuming the person who used to own that 100k mile motor was actually maintaining it properly during its life and nothing got jolted inside when that said street car was wrecked.

If you have a GOOD engine builder that actually knows what he’s doing then your motor will last a long time as long as you treat it nicely. I had my motor built in 2013 and it makes pretty close to the same numbers now after 4yrs of thrashing on it.

How hard is it to get the 305 to required power levels?

No clue yet. I can only digest so much info a day and still do my job.

I will somewhat agree with this statement. But without knowing how it was maintained its all just a gamble. In all my searching last night lowest mileage was 111k then jumped to 135k, both of those a rebuild numbers to me.
