Unless it's a race car, I have found much more fun with my cars using stock parts. I have already gone really fast in my diggers, so for me it's now all about reliability with my muscle cars. Some stock parts perform just fine on the streets and don't keep your car from performing great, like fuel pumps and ignition.
not having had the experience of really racing, the fun comes from having a car that is fast that can be used on the track as well as the street. nice situation to be able to get the go-fast out of your system on the track to that extent.
i'm starting to move more to your point of view, i must admit...
