    Questions about selftuning efi

    Yes, you do mail to him and he sends it back after he rebuilds the ECM. I pulled mine out of the truck and mailed it to him. I probably had it back within 10 days or so. Turnaround epends on how busy he is I suppose. It was close to $400 for the package I remember. I did not know anything...

    Questions about selftuning efi

    I put a new engine in my TBI truck this spring. I went with a Dynamic EFI system. Similar concept to the Megasquirt. You send your ECM to the guy -Bob- and he rebuilds it and returns it to you. Its pretty steep learning curve but some of the things are auto-tuned for you. The system can...

    Dashpad replacement options

    I dont have any experience with Cheyennes dash. I did just this week put the Dashes Direct Vinyl dash in my truck (the good one, not the plastic one). It fits "OK", took a lot of trimming and manhandling to get it installed but i finally got it in. Looks pretty good, but the fit is not the...

    Crankcase vent tube and open air element

    Anyone ever removed the AIR system before? I want to remove it from my TBI to clean up the engine bay. Do you just unplug everything and its that simple? There is some electronic "stuff" up by the MAP sensor on the intake manifold that seems to feed into the AIR system - does this get removed...

    Spring question

    I have the same year truck - 1987 v10 - and did a similar thing a few years ago. I went with a little higher load spring (it was a 5/1 spring that was around 22-2300 lbs). It carries a lot of weight without any issues. I have had over a ton of rock in the bed a few times without issues. If...

    Dynamic EFI - Anyone using it?

    Thanks for the replies on this. Brandon, since you are using this, did you know much/anything about tuning before you got the ECM? I was planning on using the method of having the Dynamic EFI folks install the new board rather than solder it in myself. Did you do it yourself?

    Engine Build - ran into a hang up with TBI intake, need help

    Thanks for the replys. I was thinking about this last night, I have a few other questions: - if I was to remove the TBi system, I know I would lose my timing control and my 700r4 Lockup. What else would be affected? - Would I lose my factory cruise control? I did a search, I believe...

    Engine Build - ran into a hang up with TBI intake, need help

    I have been building a 355 for my truck for a few weeks. Trying to do it right and use good parts and not get too crazy with compression or wild cams. Using a 12-388-4 Comp Cam and 9:1 compression. I use the truck for towing and want to run 87 octane. I ran into a issue. I have the heads...

    Dynamic EFI - Anyone using it?

    Looking at getting the Dynamic EFI ECM for my 87' with TBI so I can upgrade to vortec heads and a little bigger cam. Anyone using the Dynamic EFI system? The website is packed with info but honestly I was lost in reading it, left me more confused. Anyone using this system and have any...

    TBI Engine Overhaul - Need input

    I think I will avoid the flat tops, not comfortable with 10:1 compression on 87. Heres what I have been thinking of doing: -overhaul the short block -keeping the 9.5:1 compression, but switching to some gmpp vortec heads (new ones from jegs/summit). -Comp Cams 12-388-4 cam...

    TBI Engine Overhaul - Need input

    I spoke with a local engine rebuilder here yesterday and we discussed rebuilding my tired old TBI 350 engine. He has some ideas which I am not sure would work, wanted to run them by you all. First off, says for a little more power we could put in flat top pistons and hes guessing...

    New Exhaust Question

    Im going to order a new Dynomax dual exhaust system for my truck - going with a manifold-back dual system. One question - would it be a good idea to get some new exhaust dounuts for pipes ahead of time? Should I just assume i'll need to replace them?

    Master Cylinder - K10 to K20 conversion

    Hey there folks. Couple years ago I put 3/4 ton axles under my K10. When I did that I reused the 1/2 ton brake calipers on the front. In a few weeks I'm going to go ahead and replace those with the 3/4 ton calipers and put new brake hoses on the front as well. My question - I know the 3/4...
