I would swap in the ls1 instead of building the 5.3 if you can afford it. Much greater potential with the 5.7

Do the LS1. All parts you have on the 5.3 will bolt to the LS1. Plus the LS1 is aluminum so less weight to try and push down the highway or track. Remember there is no replacement for displacement.

You know your truck sounds good when cops ask you to get on it.

and mod for mod the ls1 is going to pull away from the 5.3. just for reference...i swapped my stock cammed 5.3 to a stock cammed LS1 and dropped 6/10 in the 1/4.
i swapped in a small cam and gained another 7/10
swapped heads and gained another 3/10
now i have a larger cam and the nitrous goes on tomorrow![]()
