This is a great motor!! I didn't get it from RSD but if it had been available here when I did my build I would have. Anyways, this motor is awesome. I have a conservative tune, but a lot of mods. Currently running 410 WHP on a 1.5 xtr (10cm housing and 3in inlet)on pump 93 with very little knock. I've had it for about 8 months and its running strong. Great motor!!! Tuner loved it!
