I'm also starting to lean to an S chassis as well considering how well they went as well.
The main thing would be to try get it nice and low in its curb weight and enough power.
Would like to run a vh45 in it been in the process of building a sc kit with a m122 would give nice low down drive out and if what people are saying they weigh they are about 150 pounds lighter then an RB if the weights are correct
