    EFE, traditional Heat riser & thermac informational

    @bucket yes. That and anymore it's not like O'rielly's has them in stock, so they must be ordered.

    EFE, traditional Heat riser & thermac informational

    Ok so lets discuss what is the same about the EFE & the traditional heat riser. They are both located in the passenger side between the exhaust manifold and the down pipe. When the engine is cold the valve shuts which diverts the exhaust though the intake manifold cross over into the drivers...

    Barn-To-Garage Renovation!

    Yes but @bucket You barn takes the cake I love those traditional farm style barns like crazy. Regardless any kind of barn to garage is pretty neat!

    Exhaust single to dual on a tight budget - Then we get into some after issues

    @GTX63 you echo my thoughts. So I used 89006 kit which is listed for the C trucks, where as the 89003 is listed for the K trucks, though I'm sure you could put a "3" kit on a C truck though. There is an extension pipe used on the between the tailpipe and muffler for the long beds like mine...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    That would be possible to do but there are to many complications. At minimum I need to add a idle kicker as the idle speeds would be different. I know your joking though. I hauled a second load this afternoon and all was well she idled well enough, drove good and sounded fine. Which I really...

    Tool battery mod with pics

    I've rebuilt my own battery packs in the past, and have soldered them. It's really quite easy if your proficient at soldering, but you got to kind of watch it, if most of the batteries are shot a new pack might be cheaper, but if your just replacing a few clapped out ones then you can save...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Well I fiddled around with the idle mixture screws this morning and settled with them a little more than a 1/4 turn leaner. No equipment was used set my ear and feel. Well that made a hell of a big difference. (Shaking head at myself), I should have known going to ported vac would require a...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    @Ricko1966 I'll read the article you linked, but also want to say this. Part of the attraction to a vacuum draw system is it's super quick and simple to set up. One bottle, one vacuum line, one valve. Adjust valve open until NOx is reduced (would really be nice to have an exhaust gas...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Ok I will think on it. To me a few bucks (or possibly just rummaging though my junk) to make a simple vacuum operated system to fool around with is one thing. Spending a couple hundred for a professionally made system is whole other ball of wax (and ain't happening). I don't think that water...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    A couple things I'm going to mention / play with. I'm not at all ecstatic with idle quality or sound of the exhaust with the ignition on ported vac. 4 DBTC is just not much and to some degree I've traded the smell of NOx for the smell of unburned fuel which is no surprise really. So tomorrow...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    I'm running stock manifolds, and yes the air pump, pumps into the manifolds. Why do you ask? To be honest at this very moment I'm a little pissed at myself for not waiting until I had $$ for the cats and just do it all at once, what with all the complications with the dual setup, I should have...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    That's my understanding. I do prefer the idle feel of manifold, but as you and I talk about these 305's were pretty much built to run with their emissions equipment, so I guess it makes sense. Sadly I liked the idle quality of manifold but that's ok. So the drive home was better, but I...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Oh I know an emissions era 305 is going to be what it is and I know it, I just know this was way worse than a normal 305 missing the cat. I really think that moving the timing back to ported made a difference. We will see when I drive it tonight. I really liked the way it idled on manifold...

    It does. I could nit pic it and the kit isn't perfect but for the price paid I'm happy!

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Update on the NOx thing. I richened the idle mixture up 1/4 turn, and drove it at lunch. No noticeable change. Then I remembered that I had switched the vacuum advance from ported to manifold, and that retarding timing will lower NOx usually. So I changed the vacuum source back to ported...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Well I'll tell ya, the cat I took off looks pretty decent inside. With a well tuned carb a cat should last for years and years, it won't last as long as it would on an EFI car though. A lot of vehicles in the late 70's though the early 90's came carb & cat equipped from the factory, and todays...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Ok now I have another issue I'd like to make improvements on and I just know @Ricko1966 will have some good ideas on this. So he doesn't have to read the entire thread, the short version is I went from a single exhaust with a catalytic converter to a dual exhaust system without cats...

    Exhaust single to dual on a tight budget - Then we get into some after issues

    Plan is to weld all the joints together after I'm happy with the setup, so that would be after the cats are on and I'm 100% sure I'm keeping these mufflers, which in reality I'm quite sure I will do.

    All you picture ****** here ya go. Since the story and the info here is completely useless maybe these will be useful.... Below, here are the exits! The Thrush turbos. That band clamp was just temp, and I can take that off whenever. Below right side muffler and tail pipe to pump and...

    1980 C10 backfires through carb under load

    Well you have taken an emissions era 305 and stripped the emissions stuff off. No offence, but it's no surprise it's no longer running well, it can be tricky at best to get these 305's to run decent after that. But the most common causes for backfiring up the carb, is too lean of a mixture...

    Pulling all the smog stuff

    @DoubleDingo You are right about that and nothing any of us say will change that. I have to admit I just went to dual exhaust on my truck, and until I get to the first of the month and get paid I'm having to run without a cat, but this is just a small two week gap and they will be back on.

    Exhaust single to dual on a tight budget - Then we get into some after issues

    I still need to do the shields and yes I know I still need to take pictures which I will do tomorrow. The low resonation I was complaining about is gone with the tailpipes installed and generally the exhaust note is more mild, which is what I expected. At idle you cannot hear the exhaust at...

    Pulling all the smog stuff

    @Radiohead & @Ricko1966 Did ya guys catch the part where he'd step over us on his way to buy a beer if one of us "strangers" was having an episode on the sidewalk. I guess he's never had help from a stranger because he was in a situation and needed help. Man I remember one time I did something...

    Pulling all the smog stuff

    I couldn't agree more, and it's nice to see someone say things like this besides me. I especially agree with this part: I don't know what some people don't get about that. It seems like it use to be team us - as in the general population, now it's me, me, me....
