Frame and Chassis Question V6 v V8

So here's a stupid question...
I understand that suspension, brakes, exterior, and a number of other things are very different or at least slightly different between the V6 and the V8. But, do they stiffen up the frame of the car in the V8 model? I'm simply curious and it's kind of been bugging me haha.

Nope, they are identical.

Not a stupid question.

Are you sure? I thought the rotors were bigger (at least the front) and the sway bars thicker?

And the answer is no, the frames/chassis are identical.

The suspension and brakes between the V-6 and GT's are completely different. The suspensions are different from a GT to a GT Vert even. And the suspension specs change from year to year sometimes. That wasn't what was asked though.

Frame/body is the same.
Some of the suspension and brake parts are the same, many are different.
A v8 fits nicely in a v6 body (i've done numerous swaps and have one of my own).

If you are going to go through the trouble to swap a V8 into the V6 body, if It were me, i would just put a Coyote 5.0L in there as my starting point. You are going to have to replace the whole drivetrain anyway, may as well put in a motor that starts out at over 400 Hp. I've seen stuff recently where others have gotten the stock gauge cluster to work in a Coyote swap, as well as the new electronic power steering.

Heck, by now, there may be some jukyard Coyote engines out there from wrecked mustangs, or maybe even F-150's that you could use. Don't know what the F-150 version has different from the mustang version. It might just be a different cam and tune.

Funny you guys bring up a swap that's exactly why I asked. my car has a lot of sentimental value and I'm tired of camaro guys giving me crap. So, I plan to leave exterior almost exactly the same (maybe different wheels?) and give the impression of a worked V6 with over 400 rwhp in a very aggressive but very quiet (if possible) V8.

I think the quieting down of an aggressive V8 will take work and a lot of patience, but I only have one semester left of college and its time to start messing around with cars more. As a drafting engineer, I think I could pull at least part of it off

I've been in the welding and fabrication business for almost ten years now, so I believe if anything needs to be adjusted as far as engine bracing placement and other what-nots I can do it myself. Eventually I hope to get up around the 550 - 575 hp and 530-550 ft/lbs mark and still be daily driven. Probably impossible, but its worth a shot

I don't have any plans as far as the actual engine to drop in yet, but it won't be small. Possibly a 427 or a 460 with a twin turbo setup.. self made bracket to attach to bell housing on a massive transmission.. custom made drive shaft.. 9 inch rear end, 3.73/4.10 gears.. and some fatties on the back

I don't know if it is completely legal to put an older engine in a newer model year car. I think you can go newer, without issue, but not the other way. I'm sure it can be done, but a coyote engine will basically be a direct fit when it comes to transmission. I understand that it uses the same bell housing pattern as the existing 3V 4.6L and maybe event he same engine mount locations. The challenge would likely come in the wiring, but as far as fitting it in, it should fit well in an S197 engine bay since it is basically the same as a 2011+ anyway.

hmm.. well nevermind on that then. Guess I'll look for a wrecked late model V8
