OK, I wasn't sure if I should paste this here, or in the driveline section. So I flipped a coin, this section won. The engine:
427 small block
240/246 Roller Cam
Cam set on 108 centerline
3000 Stall converter
I have spent the past few days afer work installing a new rear in my car. I went from a 3.07 Dana 36 to a 3.73 Dana 44. A bigger, stronger rear.
Well, forget the seat of pants stuff, because in my opinion that's just subjective garbage.
However, I have been trying like heck to get this car tuned.
Some of the issues include bucking and shuddering off the line when rolling into it slowly off the light. Also did the same thing on the highway between 50-65MPH. Also, there was a lean pop off the passenger side.
The roll off the line problem, CURED. The sputtering on the highway, CURED. THe poping, greatly reduced.
THe car isn't dialed in 100%, HOWEVER, it is a lot better than it was before the rear switch.
