5.4L Cubic Inches.
Me and My Buddy got into a long argument, he said a 5.4 Triton is a 351, but I said a 5.8 is a 351, Heck I even proved to him, cause we were talking about a lightning. He said lightnings weren't made untill 2000, I pulled out the haynes repair manual and showed him the lightning section which said 351W. He said yeah it's a 5.8, well I looked it up on ask, and showed him the 351w HO Fuel Injected Lightning was 5.8. I keep telling him that the 5.8 is the 351, and the 5.4 is the 329. Well he calls his cousin, his cousin says it's a 351, then his cousin asks his uncle, who said it was a 5.7 (Thats damn chevy motor), and then he says a 5.4 is a 351, just cause his grandpal owns one, he says it's a 351. What is it fellers, a 329 or a 351. Here's what I said, a chevy 350 TPI (Mom had one in her 86 vette) is a 5.7, so if a 350, is a 5.7, then wouldn't a 351 be a 5.8? SO guys settle the dispute. He even said on the engine it says 351, so guys give me all the pictures you have, Thanks in advance JP.

5.4L = approx. 330 cu. in.
5.8L = approx. 351 cu. in.
There were two generations of Lightnings if I'm not mistaken. The first, in the mid 90's had the 5.8 (351) HO. The second generation had a supercharged 5.4 (330).

You are both wrong, I call them 331's but 330 is also used, I can't remember the exact CC though I think it is 330.something. FWIW a 4.6L is a 281. Also I should note a 329 would technically be a 5.3L

Here is a link to a listing of Ford engines, most with both liter and cu. in. size.

What kind of pictures are you looking for? My 05 only has 5.4 on the intake - no cu. in. size. My 77 was built prior to Ford placing engine size in liters, so the original valve cover sticker indicates 351M/400.

Size Comparision: 5.4 L v 5.8 L
To anyone who is trying to settle a discussion about displacement:
To calculate cubic inches from litres:
1 litre = 61.023 cubic inches, so,
5.4 L = 329.528 c.i.
5.8 L = 353.937 c.i.
The 1 litre = 61.023 cubic inches conversion equation
is available in any standard math table.
(I will be stroking out my 5.4 L to 5.8 L soon.)
Keep in mind that the "Classic" 302 c.i./5 L and the 351 are of the older "push-rod" design, the Triton engines are OHC, so trying to compare displacement to performance is of no value.
Bruce,
since my learner's permit and a '62 Falcon.
