    350 Engine Improvements

    Hey all - long time no post, and this should actually be a rather fun one. I swapped my tired 250 out for a 350 last summer (2014) which I found for an unbeatable price on Craigslist - $125 with an engine stand. While yes it's from a '72 El Camino (rated at 165HP I believe) and yes, it is...

    Caster issues after lift?

    So I FINALLY got the 4" on my suspension that I've been wanting (and my truck is more badass because of it) and replaced a few worn parts discovered - especially a particularly dead tie rod end. Problem is... there is a TON of play in my wheel that didn't exist before. I have to turn the...

    Gas Tanks - swaps/mods

    I didn't see a more appropriate area of the forum to ask this question, so... I'm gonna just leave this here. I read 'somewhere' that a GM 20gal tank will not fit a shortbed. Just wondering if I could confirm this bit of information with the experts here. Furthermore, if this is the case...

    Eddie 1406 - Fun with adjustments

    I'm going to rip this bastard apart when I get home. After the truck sat for a good ten weeks so I could give the GTO some road time before she gets garaged for the winter, I hauled 'er back out for an axle swap and some other adjustments in anticipation of the cold months ahead. My tune was...

    Axle Swap - Fuel Econ Woes

    Am I missing something? I went from a 3.55 ratio to 4.10 to run 33" or 35" in the future. I'm running the same 31" tires and my econ seems to be cut almost in half - from 12-13MPG down to 6-6.5MPG. I was under the impression that the change in fuel econ would for this setup would be quite...

    Ready to gear - next steps

    Good afternoon, all. Long time since I posted last... Anyhow, I went down to the local upull yesterday to see what was sitting around and came home rather disappointed and empty-handed. I was for awhile entertaining bumping up to 1 tons, but figure that I'm never going to have this truck in...

    power steering/armstrong steering

    I guess this is just for confirmation... Power steering was totally fine prior to my 250-350 swap. Of course the pump I had on hand was of questionable origin. Now... low rpms = no power steering. Presumably it's time for a new pump and the steering box shouldn't be suspect since all was...

    Rochester/Edelbrock Quadrajet Information

    ...so I saw that the 1406 had its own sticky, so I figure to myself "Why the hell not". The Quadrajet has seen quite a few decades of production starting in the mid 60s and became GM's standard-issue fuel delivery system until the era of TBI engines when GM ceased production and Edelbrock was...

    Rebuilt 350 - Abysmal Fuel Econ

    Good morning, y'all... Long time creeper, first time poster - and I'm at a loss for what to check next. The backstory is that I picked up a '79 K10 for one hell of a good price - it had the 250 straight 6 in it with a monojet, SM465 trans. After cruising it for a few days, I found that it was...
