Tuning for Mild Cam, Headers, etc....

[Fast355]

Did you notice the specs on the cam you have?

HYDRAULIC − Excellent mid-range for TPI
350, injectors, plenum and exhaust system.
2000+ stall converter. Requires custom tuning.
Hyd. Hyd. 2000 to 6000 RPM 12-366-4 268XFI H13 268 280 224 231 .520 .515 113°

Without the higer stall converter, even with a good tune, it's going to be a dead zone off idle... 6000 RPM is going to require a lot more fuel then stock injectors and pressure.

As well as better heads and a single plane intake manifold.......He would be better off to pull that stick out and put something around what I put in my L31 in it.

I was cruising about 65-70 mph on the open road today, a/c blasting, listening to some Bon Jovi, rolled on the throttle a little to pass a car while climing a hill, glance down a few seconds later and I was doing 85 mph! Never had even unlocked the TCC or downshifted.

I also running a little late to work the other morning and hit the pedal pretty hard taking off from a redlight on the service road headed into a 2 lane to 1 lane merge.. Gave it probably 1/2 throttle and noticed about 30 mph, I had a floored Avalanche beside me trying to jump in front of me. I had just shifted 1-2, but floored it anyway. 2nd gear from 30 mph, I walked away from a 5.3 Avalanche. All his over cammed, over runnered, high strung, understalled, under geared, small bore 5.3 did is make noise as the old L31 350 pulled away. TORQUE is your friend in a heavy truck.

I was explaining torque to one of the Honda idiots at work and performed a few second gear starts from 0 and never missed a beat there either. With a 2,600 S10 stall its actually a pretty smooth, quick take off too.

Even on my Vortec the throttle plate opening is adjusted for the IAC to only have about 5-7 counts at 600 rpm in Park/Neutral with the a/c off and all the electrical stuff switched off.
