Just joined and wanted to start sharing my build. I have a 1977 c10 step side that bought in High School and have slowly and I mean slowly been building over the last 10 years. I have recently picked up a 01 2500 with a LQ4 and 4180e that I will be swapping out my current setup. This is going to be my first "LS series" swap and will need all the help and input you guys can give me. The truck started out with a straight 6, turbo 350 tranny and body parts from about 5 different trucks. I started building the truck with the help from my dad and a high school kids budget... cheap cheap cheap. First on the to do list was to get the truck one solid color so I wouldn't be embarrassed to drive it. Second was all about the power! Swapped out the straight six for a mild built 400 small block and put a kit in the transmission. I am lucky enough to have a local drag strip only 15 min from my house so this build is mostly intended for drag racing and fun on the streets, best time was 14.02 @ 98mph. Third was to work on the body and interior.

Last year I freshened up the engine and decided to work on cleaning everything up and start with my new theme for the truck, Fast Street Daily Driver. I loved the color and build of Stacey David's "Copperhead" truck so... Copperhead II seemed like a good name. I am still working with a tight budget and will no where come close to his build but I'm sure having a lot of fun.

Here is a photo of the truck when I first bought it.

my grandfather ordered this truck new from the dealer. he passed away about 8 years ago and I just now went and picked the truck up.  It has been in his garage under a car cover for as long as I can remember. Its a 1977 c10 bonanza with the 350 and a long bed with only 23,900 miles on it.  Everything on this truck is perfect. Zero Rust on the body.  So far I have put a edelbrock carb on it and a set of long headers.  I am trying to decide if I should lower it a little and put some 18s or 20s on it.  Only thing I have looked at is the 3/5 kit from DJM. Its a drop spindle and flip kit. what are yalls thoughts on this lowering kit?

If I go with the 3/5 kit what size tire/wheel combo do yall recommend? what width wheel and what backspacing?

Is there anything i need to look out for and any tips i should know. i have been browsing the site a little bit so i have read a few write ups on it.

also any other recommendations on some thing i should or shouldnt do to the truck. just looking for a more sporty classy look.

Thanks alot,

I am going to look at a 1988 R2500 Suburban with a TBI 454.  Thinking of using this engine to replace my ailing 4.1L and converting the 84 to TBI.  This should be interesting for me as I've never messed with a TBI before.  Stay tuned...

I.A.C. testing
(Idle Air Control)
Terminals A to B should be 40 to 80 ohms
Terminals C to D should be 40 to 80 ohms
Terminals A to D should be infinite
Terminals B to C should be infinite

(Manifold Absolute Pressure)
Typical driveability symptoms that may be MAP related include:
Rough idle
A rich fuel condition, which may cause spark plug fouling
Detonation due to too much spark advance and a lean fuel ratio
Loss of power and/or fuel economy due to retarded timing and an excessively rich fuel ratio
A vacuum leak will reduce intake vacuum and cause the MAP sensor to indicate a higher than normal load on the engine. The computer will try to compensate by richening the fuel mixture and retarding timing -- which hurts fuel economy, performance and emissions.

Check the reference voltage supply at pin C of the MAP sensor (gray wire typically).
Measure voltage between pin A (ground) and Pin C (+5 V ref) with a DVM. It should be right around 5 Vdc.
With Key on engine off the MAP voltage (Pin B, light green wire typically) should read around 4.8 to 4.9 volts. If it reads the same as pin C the sensor is probably is history.
Also check ground reference pin A. With everything off, measure resistance between Pin A and electrical ground (stud next thermostat). It should be fractional ohms

Test between blue and black wire.
.5v idle to 5v WOT
the readings should gradualy change hitting no dead spots

1. Jump terminals A and B (see diagram below) with the ignition "ON" and engine off. This will start the diagnostic mode. The computer will display a Code 12, three times, by flashing the check engine light. A Code 12 consists of one flash, a short pause, then two flashes three times.

 2. Codes will be displayed by flashing the check engine light. All codes are displayed 3 times each then a code 12 will repeat and the trouble codes will start again.
