I love real life tuning discussions over speculated theory. Have you posted pics before? </div></div> If this question was directed at me, I've got a 454 with untouched 990 heads, an Edelbrock TR2X, and a Crane p/n 134691 solid flat tappet cam (256/[email protected], 580/600, 110LSA). It runs pretty well, but I can make it better. The best pass of the three I've made so far was [email protected]. A/F ratio was pretty darn close to what it should be, but it leaned out for a moment after each shift (TH350) and went way rich when I let off at the end.

Maybe I'll try the vacuum advance this weekend and see how it likes it.
