5.3L with PD/Roots blowers towing - How's the Trans/water temps?

[RideZX6R]

I'd really like to get a maggie/TVS 1900 and add about 100whp to my 5.3 Sierra, but leave the rest stock

 

Anyone have a similar setup and tow with it?

 

I'd be towing a 3700lb car and a 1500lb trailer with a small few things in the bed (tool box, ramps, floor jack, and 2 fuel cans)

 

How bad is it?

My truck is 100% stock, but I also tow a similar setup frequently during race season. For me, stock is peace of mind. That's where your best reliability is at, no matter what any aftermarket company may tell you.
