Just wanted to clarify in case anybody else reads this. The original LPE pump was designed around the Gen 1 GT35 camshaft that has a 6.5mm fuel lobe which is 32%. The newer Gen 2 LPE pump was designed around the gen 2 GT35 cam that has a 7.85mm(40%) fuel lobe. I believe the confusion back around the time period of this thread was that the gen 1 LPE pump was only good for 10% more fuel flow over a LT4 pump with the stock LT4 cam that has the 6mm lobe.
