If it's either a '6' (windsor engine) or a 'w' (romeo engine) it will be equipped with a 4.6l I'm looking for a used 1 ton and i can find some older ones with either the 5.4 or 6.8 in decent condition Visually, the two look very similar except that the 5.4l has a longer block deck height (to enable the longer stroke of the 5.4l), making for a tighter fit in the engine compartment.

As long are both sohc 2v's or 3v's then yes you can change
The only real difference with the 5.4 vs
4.6 is the deck height Other then that they are the same engine, both from the modular family There other difference is the intake, but since it's for a truck that's not an issue. The kits below are our most popular conversion options
The easiest way to tell the difference is to check the 8th digit of the vin code A vehicle equipped with a 5.4l will have either an l, m, or z for a naturally aspirated version If you donβt have the vin, you can tell a 5.4l from a 4.6l by looking at the deck height The 5.4l is about 1 in
Both have the same aluminum or cast iron block construction, depending on the manufacturing year
However, they have minor differences in their power and torque ratings. Ford 5.4l triton 3 valve engine has redesigned cylinder heads with two intake valves and one big exhaust valve per cylinder The 4.6 liter engine is physically smaller than the 5.4 liter engine, so if you are able to visually inspect the engine, you can tell the difference by size. Reliability, parts and cost of repairs is going to be pretty much the same assuming they were cared for equally over the last 15+ years of their lives
The 5.4 is the stronger engine with better torque, making it the better option all things considered. Bad years for the engine
