    Oil pressure gauge - pegs right...

    Oil pressure gauge on my 1985 K20 historically has worked with no issues - replaced the front clip and the bed, new tanks etc. Cranked it for the first time in a year or so and now the oil pressure gauge pegs to the right. It seems to peg the right after cranking it (truck cranks up perfect and...

    Need a bit more oomph...

    Much appreciated on a cam direction… You mention that the heads are the biggest problem, thoughts on a direction for heads that won’t break my marriage?

    Need a bit more oomph...

    Thanks for the feedback- The truck has 4:10’s… I would use it mostly as a daily… (I have a Duramax for any substantial towing)… most of my driving is under 2500 rpm… so lower end torque is the desire.

    Thanks for a starting point… I’ll work on getting pics once I get back to my shop.

    Nv4500 ‘rattle’ between acceleration and deceleration…

    I thought I'd provide a follow-up to this post. As stated above - I installed a slip-yoke 'cv' joint drive shaft from Tom Woods Driveshafts to solve my 'rattle' issue from the drive train. I drove it about 800 miles to Breckenridge CO via Amarillo and Colorado Springs. When I got to Colorado...

    Need a bit more oomph...

    I have a 1985 K20. It appears the previous owner put in a crate 350 - likely the lowest horsepower/torque engine - it doesn't have a ton of guts. A few months ago I swap out the SM 465 for an NV4500. It has an edelbrock cab (unknown which carb). I'm about to swap out the front clip (rusty...

    Speedometer cable extension???

    I have a 1975 GMC Jimmy - and recently swapped in an NV4500/NP208 - previously had the SM465/NP203 - consequently my speedometer cable is about 3" short. What are my options? Can I order somewhere a longer cable or can I add an extension - if so where can I source what I need? Thoughts?

    Nv4500 ‘rattle’ between acceleration and deceleration…

    I suspected it may be the single u-joint at the transmission where originally there was a CV joint...and after speaking with the technician at Tom Woods Driveshafts - he felt certain the issue was having two u-joints over-spinning the internals of the tranny. That is why it was yelling at me AND...

    Nv4500 ‘rattle’ between acceleration and deceleration…

    Just a quick update... I was able to order a slip-yoke CV joint driveshaft from Tom Woods as no one else seems to be able to source the slip-yoke CV joint. The new driveshaft WITH the slip-yoke CV joint was less expensive than Inland Truck part's new driveshaft with no CV joint... and got it to...

    Reverse light plug - SM465 to NV4500???

    Nevermind... I think I found a solution:

    Reverse light plug - SM465 to NV4500???

    Is there a way to convert the old style plug (for the SM 465) to a newer NV4500 plug - on top of the tranny?

    Nv4500 ‘rattle’ between acceleration and deceleration…

    Thanks for the feedback... it is a blazer, and it is lifted and it had a CV at the transfer case. I'm hoping getting that added back to the new drive shaft will allow it to run smooth with the NV 4500 as it did with the SM 465. Here are a few pics...

    Nv4500 ‘rattle’ between acceleration and deceleration…

    The rear diff is angled up to point almost directly 'at' the transfer case input shaft... so the rear diff and thus the u-joint and drive shaft are 'in line'. Again, this has all been working perfectly for a number of years... until I swapped the transmission, transfer case and Inland remove...

    Nv4500 ‘rattle’ between acceleration and deceleration…

    The transfer case is at 4.5 degrees, the drive shaft is at 17 degrees - so a 12.5 degree difference... I'm thinking that is the issue with no CV joint to mitigate. The driveshaft I had built for the 203 (2 years or so ago) had a cv joint built into the transfer case end of the drive shaft. I've...
