Re: 68 c10 6.5 turbo diesel

i'm running a full manual 4L80 in mine. gonna get this shifter:
http://www.tciauto.com/tc/fast-gatetm-shifterhtml
looked at a lot of them and seems like the best.
chasing fuel leaks and changing filter faster, relocate the FFM to fender.
for a better connection, do the battery bolt mod.
was really surprised you decided to go electronic.
love the 2 piece crossover. would make it easier to mess with.
truck looks great and runs even better.

Thanks. Yea I put stronger gears in it and has held up fine. 4l80 takes a lot of power to drive. I didn't want too lose that's much power. I went electronic because at the time I could get the most power. Now their building pumps that run like garden hoses. It's nice though with cruise and high idle.

So looks like you must be right. All vehicles made after 1/1/96 had OBDII. I wonder does that make it more complicated or less?
I'm just following thru this build that Marv sent me and wanted to clarify a few things since i'm the 6.5L nut.

The oddball injection pump was in 1994 and has DS4-5068 on the label. It's an easy fix in the PROM chip to swap that pump onto any year 6.5. Easy is a term relative to me since I can do the tuning.

Don't let any years of the 6.5 electronics scare you away. I can help out, just let me know and we'll continue these sweet builds!

The 4L80E does take a bit of power to drive but on the 6.5L's it's also a slug due to heavy torque manage settings in the PCM. Slap a 2200 stall converter in and remove the torque manage with an Intercooled Holset, and you are pushing the limit on the torque rating of a stock 80E.

Re: 68 c10 6.5 turbo diesel

Just read the first post with the "mild 27psi". That is not mild on a 6.5.
