    Vibration at 2500-2800rpm

    Not the original, I got it with a destroyed 351 and out a 302 that had been newly rebuilt in it because of my Financial limitations at the time. From what I recall it is a 78. I should look again

    Vibration at 2500-2800rpm

    I haven’t tried with no belts. But I’m on my 5th fan… so I can rule the fan out. I’ll try to pull all belts. Rather that then tear down the motor again.

    Vibration at 2500-2800rpm

    I have had vibration since putting a rebuilt 302 in my truck. At the time I put a rebuilt Dana 20, 700r4 and new driveshafts. So I thought it was my driveline. I finally drove without the rear driveshaft and vibration is still there. Under load in the highway between 60-70mph it seems very...

    Torn on proper gearing

    Thank you all for the replies! I do a lot of highway driving, but also drove from sea level to 6,000ft often. I do take it off roading, but definitely more highway and surface street than anything. I like the idea of trying the rear out first. And I’m going to call a few other shops to research...

    Torn on proper gearing

    I put a 700R4 in my truck about 5 years ago from Bowtie. I already rebuilt it last year, so it only lasted 4 years. I have a feeling this is due to my gearing. I have a 2.5 inch lift, running 33’s, Dana 20, 700R4 w/ overdrive transmission, and stock 3.50 gears, 9 inch rear. I’m very sluggish...

    Death Wobble is back

    Im back with another death wobble issue! When I think I fixed it, it comes rearing its ugly head again! I had sever death wobble a few years back, turns out it was a broken track bar bolt weld. I replaced the track bar and its bushings and did a very heavy weld to keep the bolt in place. Last...

    Fitech RPM Noise Code

    I can’t believe it! I got the truck to crank and sputter. No rpm noise code. BUT it won’t stay running. Just shuts off immediately. No codes. Didn’t change timing. I did however change my ignition module in my distributor. Put my old pertronix back in that it worked with before with a new module...

    Fitech RPM Noise Code

    Maybe I’m confused, your tach wire is also your ignition wire? I have a ignition wire (when key is turned) going to the Fitech harness, then my tach wire to the coil. I did put the tach wire into a braided line and grounded it. Didn’t help. I thought I did a factory reset. I’ll try again.

    Fitech RPM Noise Code

    I installed yesterday and it isn’t helping at all. I was hoping to take advantage of the start timing retard too :/

    Fitech RPM Noise Code

    Digital ignition came early. Hooked it up. Symptoms are no better. Back to square one. Will be removing and trashing tomorrow. Fitech has been no help unfortunately .

    Fitech RPM Noise Code

    Ok, I’m waiting for digital ignition box, apparently it is hand built and takes 3 weeks... I called Fitech again and they told me it’s because of the coil I had... I had a perteronix flamethrower 2 they said their system only works with msd blaster 2. After 2 .5 years of using pertronix I found...

    Fitech RPM Noise Code

    I’ll give that a shot, I wrapped my tach wire, didn’t help.

    Fitech RPM Noise Code

    I did, and have read what I felt like was every page on the internet. I even wrapped my tach wire in foil. I was just hoping there was some useful insight here. I’ll dive back in. Last resort is wrapping tach wire in this. Just ordered.

    Fitech RPM Noise Code

    I have had a fitech installed for 2 years on my truck. 2 weeks ago I was driving and it shut off without warning. The handheld showed. RPM Noise for a code. I checked everything in the truck, every wire, re-ran my tach wire to try and reduce noise from other electrical components. Cleared the...

    Timing frustration

    Dirt Donk, Hopefully this answers some of your questions and brings clarity. I know my firing order is correct, I tried the other firing order for the 302 around my year and it sputtered and shook and wouldn't start. I did feel each consecutive cylinder after as well. This first data log is...

    Timing frustration

    I am going to try and clarify a bit more. 1st I want to apologize as I may not know the proper terminology 2nd, I have a lot of unknowns with the motor. I don't know what type of heads I have, or cam. I was told it was a fully stock motor. I do have Fitech, but without timing control. This...
