He said with the smaller 2nd pulley he was wanting what a 383 4bbl had for power wise. That was the goal. He came in short by very little. But he stated that A Body 383 had the crappy exhaust manifold so in fact it did meet it. Fribuger(so?) Kinda hinted he cheated. 341.3 Max Toqure at 4800rpm and 328.4 HP at 5500 rpm I think A Body 383 was 300HP and B and E was 330 _335? So you be the judge.
