6.2 injectors normally use the long bodies vs the 6.5 that uses short body injectors. So you run into clearance issues with a 6.5 turbo manifold with 6.2 long body injectors. Simple fix is it either get 6.5 injectors, or Ive seen guys space the manifold off the head with a aftermarket manifold flange sandwiched between the head and manifold.
Also your pump is a normal .290 6.2 pump. Not worth building if your looking for more power. But if you just want a stock setup you can probabply get close too 200hp with is cranked up all the way.
