Any idea on what the weight difference will be between this and the 6.2?
The sohc rapter v8’s were about 600lbs.
This engine could be closer to 500lbs.
For comparison, the voodoo 5.2L is about 415lbs, and a 455hp 6.2 Chevy lt4 is about 450lbs iirc.
Woah, are these #'s fact checked? Wouldnt think a 4cam voodoo would be that light.
I know its dreaming, but this was almost exactly my thoughts! Give me a low-tech Cobra, Boss, Mach 1, whatever they want to call it, with a variant of this engine and a 10r. Keep it light and cheap and you'd have the new muscle/pony car KING. All the technology in the latest vehicles is amazing, but damn, give me a new terminator with no widgets already!
The voodoo mill is very light. It’s actually lighter than ferrarri’s 4.3 and 4.5L. Those mill are 425-430lbs iirc.
The voodoo mill is like 415-420lbs.
I don’t know what the 7.3 weighs. I’d imagine an aluminum one is 500lbs and an iron one being 600.
I thought someone stated 500lb for the 7.3L
I think @jeffh81 said it’s 500lbs and can be punched out to 500ci but he was joking I thought.
If he was or whoever said it was serious/factual then wow
Edit* my memory was snopes verified.
Can someone 100% confirm le claims? If le 7.3 is 500lbs and can punch/stroke out up to 500ci, then god has blessed us all.
Let me look. It was on another forum i think. Might have been the engineering video that mentioned it. May take me until tomorrow to find it. Im having truck issues right now with my junk so im busy
2020 Ford F-Series Super Duty Engines and Transmission: 11 Power(train) Points - Motor Trend
I'd like to thank everyone that's planted the seed of a high powered NA Boss 429 in my mind...just when I convinced myself I was 'happy enough' with my current ride.
I’m seeing that ford says this 7.3 is 50lbs lighter than the 3v v10 which weighs 620lbs. That would be 570lbs give or take.
Let’s assume an aluminum casting could shed another 70-90lbs and we may be looking at a possible 500lbs or lighter big displacement v8.
I love that the bore is so big, yet the stroke isn’t insane. 107x101 4.22x3.98” is oversquare and translates well for different future applications. As that sits it supports over 6,000rpm redline in truck-guise.
It would not take much tweaking to achieve 7000rpm which is plenty for a boss 429. Trinity gt500’s hit 7k with 4.16” stroke for context here.
The stroke on 5.4’s is LONGER than the stroke on this engine. That is an excellent thing given this 7.3 is also a narrow design.
I've been hearing that it's a square setup.
It’s pretty close if I read the dimensions right, from press releases and reporting here on svtp I’m seeing 107mm bore x 101mm stroke, but I don’t know the actual rod ratio and piston dimension.
Do we know deck height?
This and the 6.2 are iron blocks. The coyotes and LS are aluminum. I really wanted to do a 6.2 build and we actually had an engine plan accepted to Engine Masters but that 6.2 was heavy and large for a Mustang.
A future aluminum block 7.3 would be awesome.
Still a canted valve headed aluminum 9.5 deck Windsor is still very relevant in pushrod racing.
That short block is lookin like a modern day 427 with a steel 428 crank thrown in, 6 bolt bottom, nice......
What's that BORE SPACING!???
Not sure which thread to put it in, but thought this was interesting!
Ford Says Its New 7.3-Liter V8 Can Fit In The F-150, Mustang
Like that's a revelation. The 7.3 longblock is obviously more narrow than a Coyote.
Agreed, but I recall some debate about whether it would fit or not. Or am I having a case of oldtimer's and thinking of the GT500 5.2 not fitting? TOO MUCH Ford excitement lately!
With the proper oil pan and intake a 7.3 should fit basically anywhere a Coyote will go. The biggest difference will be length.
