I finally finished putting the motor back together on my car. Its running pretty well, except that I feel very slight bogging at low RPMs. Once I reach about 3k it start to pull smooth, but in the low 2k RPM range I feel it slightly sputter. I adjused my timing to 15* and my fuel pressure is 39psi with vaccuum off. Anyone know what this can possibly be?
Setup: GT40 heads and intakes, 1.7 rockers, mild cam, full exhaust (shorties, x-pipe, etc), a/c and smog pump delete, under drive pullies, densecharger w/ larger MAF (forgot size), 65mm TB, and all the other little bolt-ons...

I saw your post over on corral. I think the b-cam just leaves a little to be desired down low.

Did You try pulling the codes on the computer? Is it an auto or a stick? stock converter's or off road? What about basic tune up like plug wires or fuel pump?

SilverLX...I havent turned the timing down yet. I will be once I get home today. JohnB said to turn it down to about 11-12* and the fule pressure to 38-39 psi. Its currently at 15* 40psi.
AJBlackGT...yes, I saw your post over there, thanks. If it still does it after changing the timing, I will assume that thats the reason.
Thanks for the input guys ![[patriot]](graemlins/patriot.gif)
