Built engines and performance packages

[DPViper]

I have been looking for a GTS and I have come across a number of nice cars with "built" engines and performance packages from Hennessey (can I say that here?) and others. How do you evaluate these type of cars? Is there a reasonable way to verify the engine is actually improved? Should these cars be more or less desirable? Thanks for the comments. Doug

MORE valuable but its tough to get your cash back on mods....

Get a motor build sheet -dyno sheet .Even with this the only way to really tell if the bottom end ect has been done is to pull the heads and pan .

Here is a good example:

eBay Motors: Dodge : Viper (item 250291545942 end time Sep-12-08 13:55:28 PDT)

How is a buyer supposed to verify the engine work was done as described? I'm sure it is better/safer to buy a stock car (and then mod is yourself) but you save a whole lot of money if you buy a car already modified. Thanks

Buying that one is like buying a pig in a bag. No way of knowing what John actually put into it (or didnt?) and its not worth dismantling the whole thing.

might wanna ask a few texas owners if they know the car or owner. and start there. unfortunately that tuner does have a rep for NOT doing what he was paid to do in the past.

meet owner at a chassis dyno and get a printout stock hp #'s are fairly well known and if "built" to whatever degree should have greater hp than known stock nums

The website states 605rwhp and 605tq.Take the car to a neutral dyno and spin it!
