Re: Can't decide between 5.3 or 6.0

I went from a 305 to the 5.3 and don't regret it at all. Truck ran a high 17 sec and dropped down to high 14s with just the engine swap. Ran the same trans and rear end from the 305. I should drop to high 13s with a trans and gear swap actually a full rear end swap.
