SRTs are pretty much bullet proof. Just don't get a boost controller. Quick power for the dollar but hurts you in the long run. Thats the only reason I'm having to rebuild my engine, spiking 26psi setting to 19-21 on stock everything. Surging and all that good stuff. If I had been smart and built the motor instead of trying to get quick power of it, then I wouldn't have this problem. You can't go wrong with a cast iron block
