That they most certainly has. Prices for these vehicles are in the $2,000-$3000 range in my area and out of the box their pretty quick. The optispark has been and is their biggest problem but there are products available to help with that. 24x and the new torqhead systems totally eliminate the optispark all together and allow the use of the faster and better LS based PCM. The torqhead system allows you to not even open up the engine to install; it's virtually plug and play and everything is external. There's also the LTCC system that still uses the optical sensor but eliminates the spark going through and lets you use LS coil near plug system. I'm just looking for people to think about them as more than the "oh it's just an LT1." I'm the guy in my vehicle group that has a worked up LT1 and get made fun of for it because I don't have an LS in my car; but yet everyone I've raced has seen my tail lights and makes them look at the LT in a new light.
It's the nearly forgotten engine in performance history that in my opinion deserves more respect that what most people will ever give it simply because of the optispark "failure" and the incredible LS engine
