Aftremarket block may not make more power but it let's you run a lot more boost or nitrous and turn more rpm which means,a lot more power. I've never had race gas or mixed gas in this car. And yes,you don't use overdrive goung down the track but the aod still uses up more hp. I know what that car runs,I don't have anything for it. Not even close. Like I said,I'm too slow.
