by the time you were done spending money making the v10 fit, you could mod the 427 to the point where it would just simply curb stomp that poor v10 right off the road.

The Viper motor makes simialr power to the LS7, and when you factor the exhaust manifold (wouldn't call them headers with all thr estrictions you'd probably have) you'd have to use to make the V10 fit, it would be less than the LS7 probably. Not to mention ALL the extra weight. I also don't think the motor would fit without serious body alteration. They are a very long and tall motor. They just sit very low in a v1p0r, but the front of the motor would go VERY far into the hood, and you'd have a hard time getting air to it. Not to mention the cost involved. ECM to control the motor and car, fabbing up the parts. The transmission issues (tq tube etc) if money is no issue, then build an LSx motor.

A good idea would be to put an ls7 into the viper. I like the way vipers look. I HATE the way they sound. They are pretty quick. I would say the ls7 makes near identical power to that of the 505ci viper engine. Not to mention it would be much lighter.
Its about potential, do you think an 8 cyl can make the same power as 10 mod for mod? I mean be realistic... vipers own all.... ls7 is a race motor catered for the street, a viper engine is fairly mild for 500hp....

the viper has more displacement, and because of that, it makes more torque over a broader curve... so while i prefer the genIII+ motors, i know that a 500hpviper motor is putting out more then a 500hp genIII...
however, vipers dont "own all".. frankly i think they're kinda silly.. they make shitty drag cars, shitty road course cars... they purly exist to "be cool"
in anycase, you cant go "mod for mod" between any motors of such different design, but if you want to go "HP per dollar" or BSFC or parts availability or any other actual, meaningful, method that can be quantified, im sure SOMEONE would give you a actual answer.
but a broad overgeneralized question such as that has no meaning and is only fuel for a debate run by idiots who have nothing better to do, and probably minimal knowledge of both motors.
oh, and BTW (i know im just fueling it again, but what the heck...)
BOTH motors have the same potenial... because they both can make enough power to require everything to be replaced...

The newer Gen II+ Vipor motors can't handle a lot of mods without beefing the internals, as opposed to the pre 96 motors, which can take a lot pressure abuse (boost, spray etc) on a stock motor. The vipor motor cost quite a bit to mod bolt-on to bolt-on, but the mods are nice. You can get Roe Racing to supercharge your vipor and get about 900-1000rwhp for $15k or so, but you can easily do the same for an LSx motor.
Now since we're talking about a C5 chassis in both cases, that's the only apples-apples comparison here.
BTW v1p0rs sounds like GIANT HONDAS. I can't stand the sound of them.
