If it wasn't for stock class pulling rules I would just run a 68 Stage 2R on our shop work truck, but because of them I started with one of Mark's 68 Stage 2Rs and built a stock appearing 2.5" turbo with a stock front cover and a 3794BMW wheel. It turned out awesome for towing, ran 11.81 @ 115 on it's first 1/4 mile pass and won 2 classes of pulling at it's last event. At Rudy's it took 4th in the work stock class and was 2 feet behind a built motor, stage 2 head, 9100 cam, truck with a Danville 72mm on it (shouldn't have been in the stock class, but after I tuned it the next day it would have been a lot further than 2 feet ahead of the work truck). Even though it isn't an out of the box Stage 2R, it is still a testament to how awesome the 68 is if you can get away with running it. And even if you want a stock appearing one built like mine, Mark could take care of that for you - I just didn't have time before Rudy's to get one from him and had a 68 and a 3794BMW wheel on the shelf, so I did it myself - I will not be making or selling them.
Here's a video of one of the pulls - I got red flagged and had to let out before hitting pavement.
