Well, it looks as if my 5.3 was short lived. Its been smoking at idle and since i drive the thing daily i can't have it down for weeks at a time. I want to have a backup so that when it goes i can swap it over in a day

I want a running shortblock with under 100k that i can swap my worked heads and cam over to an drop it in an keep on trucking.

Im in west fort worth, but i am willing to drive if the price is right.

Let me know what you have

Thanks,
Alex
