I'm currently towing 5800 Lbs dry with a 5.3 Chevrolet Suburban. I'm curious if anyone has towed with Ford 5.4 and Chevy 5.3 and has an opinion as to which is best, based on putting that power on the pavement. Which is better for towing or are they about the same?

I towed with two 5.4's, an 08 4sp and a 2010 6sp. Both 3.73 gears and both 145"WB F150's. Plain and simple the 5.4 is a dog. Towed two TT's, one weighing 4050 lbs loaded the other 7200 lbs loaded. Towing the loaded 4050 TT was great. Towing the 7200 lb TT was not fun. The 2010 5.4 6sp has no OD lockout so the trans is always shifting up and down. Any little rise or wind change made it shift.

There are a lot of variables here that would make it hard to compare. With the 5.3, what year? Depending on the version of the engine they ranged from 285 hp. to 320 hp. Gearing is also another consideration.

There are about 10,000,000 5.3s and 5.4s and some are as different as apples and dog poo, so what is the question specifically?
You’re talking 2 trucks of the same era, so upgrading from a 5.3 in a GMT 400 truck to a 5.4 3v and a 6 speed would be an upgrade. If your 5.3 is gmt 800 with a 6 speed, then pick you favorite grille badge.
Both are good engines and both have their own sometimes major issues.

The 5.3L was never available in a GMT400.
I've never towed with a 5.4 but I've never heard anyone claim they made much power. Any owner I've ever talked to claims it can't get out of it's own way.

IMHO the GM 5.3L is much better than the Ford 5.4L in terms of serviceability and overall reliability. If you want a Ford go for the newer 5.0L.

If you want a Ford, go with the 3.5 ecoboost and the 10 speed transmission.

I'm impressed with mine.

Correct meant gmt 800.
Either way, OP, who left the thread is talking about a 5.4, so obviously nowhere near buying a new truck.
10speed Eco has nothing to do with his question.
