    Anytime you have a mysterious crank no start on a corrected firing order distributor cap, I always start by trying another cap. I've lost track of how many times I've seen them with fuel, good...

    The harness change occurred mid year 93 because of all the leaks of the early style harness. The harness is compatible either way. I know you'll have to do some rewiring and swap your drac to a vssb...

    I have an 01 5 speed .bin read from a gmt-800 with a 5.7l. rescale the MAF for the 75mm MAF that the gmt-400 used(gmt800 used an 85mm), and swap the VE table from the express van, and you're good to...

    I almost went with the flex-a-lite fans, but the cost was just too high for me. I bought a brand new set of Spectra fans for an 05 silverado from rockauto for $142 + shipping and picked up a front...

    The seal is available as 16194007 from ac delco as I just bought one for mine when I was doing my marine intake swap. My original was deformed and wouldn't hold the o-ring fillers.

    I would recommend a Transgo HD2 shift kit and a new seperator plate. And I'm not a huge fan of the vette servo myself. I used s 4l70 servo in the last one I built and liked it alot better than a...

    Does this 4.3l have 1 or 2 knock sensors? Most 4.3's I've seen use 2 knock sensors. I fought one before and turns out there was a 2nd one I didn't know about and if the ECM detects a problem in...

    I did alot of injector research and I ended up using the injector values from a 02 LS1. There injectors were 25.2 lb/hr at 43.5 psi which is identical to the marine injectors. The only difference I...

    The 4k ohm knock sensor is for the 7427 ecm. The 0411 uses a 100k ohm knock sensor. You have to match the knock sebsor to which engine, single/dual knock sensors, separate knock module or integrated,...

    For an 0411 you can select 1 or 2 knock sensors and which type in the programming.

    No 95 4l80e 4x4 had an output reluctor wheel stock. The hole is there and it may even have a speed sensor installed instead of a dummy plug, but if it's stock, there is no 40 tooth reluctor. ONLY...
  12. That appears to be a 93 model if I'm reading it...

    That appears to be a 93 model if I'm reading it correctly. If it works with a 91-93 ECM, then it is most likely correct as ONLY the 91-93 model 4L80E had the output reluctor installed in a 4x4 4L80E....
  13. Swapping 88 R30 from 7747/th400 to a 95 7427/4l80e

    I've been reading and reading and reading some more on this. My neighbor has an 88 R30(square body, 2X4, dually, 4 door) with a 5.7L TBI and a turbo 400. His trans crapped out on him, but he really...
  14. I was speaking of pickup's, but everything I had...

    I was speaking of pickup's, but everything I had found said that all vans also stayed with the low pressure system, even the rare 96 TBI vortec. I know that non road going TBI switched to high...
  15. On 94+ the 4 low input is connected to the ECM so...

    On 94+ the 4 low input is connected to the ECM so it knows when it is in 4 low to modify the speed sensor reading by the low range ratio. Not sure if the 2x4 BIN file will have the 4 low tables in it...

    To run the 7427 there's a few changes that I know you'll have to make. The trans change is you can simply remove the early force motor and install the 94+ style. This will work, but you will have...

    That was just for a read, not a write. I've done 3 reads now on 2 different PCM's, and it has averaged 50 minutes for each read. Cal flashes were pretty quick though.

    I have an SX cable and it takes me right at 50 minutes to read an 0411, haven't tried a full flash yet. I wished I knew how to make my TECH 2 work with it as that would flash ALOT faster.

    For the trans, it goes 91-93, then 94+ as far as controls go. Yes the harness changed mid year 93, but the pcs and valve body did not change until 94. So use the correct programming for your trans as...

    Most that I've seen who even swapped one in eventually ditched it and went with an opti-shift. And if I'm not mistaken, that TCM will only work with the 91-93 4l80e that didn't use a vssb for the...

    I've used the Comp XE249H in a few TBI 5.7l trucks with stock tuning, and they ran really good. I'm sure a tune would have helped, but the one with ported swirl port heads and headers put 260hp down...

    It's been awhile, but it was a Crane set of beehives, and I believe they were LS6 style retainers. The stock locks protruded out of the bottom of them.
  23. I've done 3 sets now and each one only had...

    I've done 3 sets now and each one only had .500-.505 after fully seating the seals and using the 648 locks. Had lots of clearance to the retainers, it was the seal to lock clearance that was the...

    What I'm talking about is the well known lift limitation on stock vortec heads without machining the guides down. Even with comp 648 locks you only have about .500-.505 of clearance between the top...

    You always want to degree your camshaft, not just set it 4 degrees advanced. It is better to set it straight up if you're not going to degree it because I've seen some chains with advance built into...
