ERA FIA 2088,

I recently installed a set of 48 IDAs on my 1966 GT 350 Replica and would like to share my information with those listed in your chart. Here are my specs:

Engine - Ford 302
Displacement - 331
IN dur @50 - 232
EX dur @50 - 240
IN lift - .565
EX lift - .574
Lobe Separation - 112
Venturi Size - 37
Main Jet - 135
Emulsion Tube - F11
Air Correction - 110
Pump Jet - 50
Idle Jet - 65
Idle Jet Holder - 120
Carb - 48IDA

Before I installed the Webers, my car showed 365 HP on a chassis dyno at the rear wheels with a Holly 715 cfm Shelby carb mounted on an Air Gap manifold. I also have AFR heads and estimate my compression ratio to be approximately 10 to 1. With the new Webers, it feels like that performance has been improved over the range from 3500 rpms to redline at 6500. After I complete the jetting sequence using a wide-band O2 sensor, I will try to put it back on the same dyno to compare results. Since I have the dyno graph from the previous configuration, the comparison should be interesting.
