First off, my timing is way too high, it's jumping off the marks, and I try to turn the distributor, but I can only turn it so much and it hits the back of the intake where the bolt is on the distributor.

Second, I replaced the fuel pressure regulator and the fuel pump, and it's still above 90PSI. Is there a way to figure out what the problem is before I swap out all of the fuel lines?

 

The fuel pump I replaced was the Granetelli 255LPH from Jegs, and the FPR was one they found that had the bracket on the correct side for my mounting purposes was for a Buick Rendevous.

 

Jump a tooth or two on the dist and set the timing again. It doesn't necessarily have to point at #1 TDC to run, only the orientation between rotor and points is important

What regulator are you running? When I did the lt1 intake conversion, I was forced to use a SLP AFPR for space and even that had to be turned around
