Cant have both?
I'd go for the later year. Are you planning on FI?
If I had a viper I don't think I'd be too concerned with making even more power.
ABS is good. It prevents you from flat spotting your tires and has no downside.
Aren't Vipers very costly to maintain? I recall reading an R&T article about them as used cars and it suggested they require frequent, expensive engine maintenance. There seem to be some real experts in this thread, something I most certainly am not, so I'm interested in being educated.
The engine came from a truck, so who knows if it's running close to max compression...?I wouldn't think you'd need lower compression pistons to run a decent amount of boost. From what I can tell, the Viper GTS V10 has 9.6:1 compression which is plenty low unless you're looking for 20+lbs of boost. An LS2 has 10.9:1 and an LS3 has 10.7:1 and they both get away with 6-7lbs with no meth or ~13lbs with meth. They both have bore diameters approximately equal to the V10 (4") so unless the head design is more prone to detonation, I wouldn't think you'd need to lower the compression. If it responds anything like an LS engine, it will make some serious power on 8-10lbs.
