I posted this in the new trucks section, but thought it would get more views here.

5.3 rebuild OR 383 crate engine (GM P/N 12497317)

I have a 2001 burb with a 5.3 engine. It has over 150,000 miles and I am planning on either rebuilding it with a 4340 crank, JE pistons and Oliver rods or use the 383 crate engine. I am gong to add a P1-SC Procharger. I plan on keeping the static compression between 9.3:1 and the original 9.5:1

I have had a good experience with Procharger in my boat. It is a 540 cubic inch Gen VI with a M-4 Intercooled carb engine. It is approximately 820 HP at 6 lbs of boost.

I would like to hear advice from anyone who has used a centrifugal supercharger on a 5.3 or has swapped to a crate engine.

Thanks in advance for your input.

I just looked at the 6.0 and it looks like the ticket.

Here is the best price I found so far.

I would think that this along with 1GI216-SCI Procharger system for 99-03 GM 6.0 would be a great all around performer.

I plan on running FI. I would think upgrading to the 3 core intercooler vs. the standard 2 core would give me a margin.

Can I use all of my accessories alt, power steering etc with the standard 6 rib belt? How about my FI and intake? What if anything would need to be changed? Do I need to reprogram my ECM? If so, who would you recommend?

Thanks for the feedback.
