mattb73lt Posted August 18, 2022 Author Share Posted August 18, 2022 Not really. I only heard the center drop once when I bought the engine 20+ years ago. The backdrop sounds really throaty when you rev it up, with a good bark. The video I have of it revving up sounds really good with my headphones because of the bass. Hopefully, I'll be running it around soon so I'll have better sound with a load on it. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post mattb73lt Posted August 18, 2022 Author Popular Post Share Posted August 18, 2022 Moving right along!! Power steering is complete and works!! Mounted the steering cylinder and fabricated the last two lines I needed. No leaks and it's definitely a help over the manual box, but the Sheppard box in the other truck is a more powerful unit. But no complaints on this Garrison unit. Almost done modifying the floor pans, cutting a slot for the pedal arm to pass through and travel. Need to make some filler pieces to close up the old gaps, the rest and the steering column hole I'll cover with a 1/8" rubber sheet to seal the rest up. Pedal position is much more comfortable as my heel rests where the pedal base was and the ball of your foot easily presses the pedal. Also have to mount and rig the new accelerator pedal. That should be easy as it's a brand new kit From LOKAR. Pushing hard this week because next week will be busy with work through the weekend. 7 1 Quote Link to comment Share on other sites More sharing options...

Paul Yes, there are two patches of plywood, between the fixed floor and the removable panels that go up to the firewall. I used marine grade plywood and made some of the openings smaller. This was the piece before I cut it in two, like the original. 1 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted August 20, 2022 Share Posted August 20, 2022 question?? baskins reefers had 5/8? double sided laminated plywood for the walls inside. would that shed the moisture as good as marine grade plywood? i know it worked great for me turning a day cab into a"bunk" between the seats for my "motel lay-over " LOL ..$$$$ wise don't know the difference. possibly the boys at atlantic would have a partial piece big enough. weather on outside floor might run off with the laminate. just paint the wood exposed edges Quote Link to comment Share on other sites More sharing options...
Popular Post mattb73lt Posted August 22, 2022 Author Popular Post Share Posted August 22, 2022 I finished up the accelerator installation on Saturday. After warming up the engine, I backed down to the street. This gives me almost a 100 yard run to the barn. In first, I walked the compound up, under, direct and over, before I had to get on the brakes. Well, the 220 and exhaust didn’t disappoint. It was LOUD and had quite the bark, much more so than just revving it up. I’m going to run it as is for now. Although I may need to rethink the noise level. It sounded incredible. I don’t have a Go Pro camera so no video of it. 2 1 1 Quote Link to comment Share on other sites More sharing options...

You could always treat it with a preservative or some kind of waterproofing treatment. If you do that and it’s good quality plywood, I think you’ll be fine. 1 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted August 22, 2022 Share Posted August 22, 2022 It is amazing at just how loud things can when no turbo is fitted and I guess it should be no surprise just how deaf a lot of people are as they get older A muffler might a good idea of some description in the future, then again once driving about with the windows up at speed it might be quite bearable as your moving pretty quick away from the noise Paul 1 Quote Link to comment Share on other sites More sharing options...

Mean Green Posted August 23, 2022 Share Posted August 23, 2022 My B model started out with single 4in straight pipe that wasant bad then I went to dual 5 in straight pipe no turbo and it was super loud then I turbocharged it and it sound way better but it's a thermodyne so to compare it to your cummins isn't a really good comparison . Keep up the excellent job your truck looks amazing 1 Quote If your going to be a bear be a grizzly Link to comment Share on other sites More sharing options...
mechohaulic Posted August 23, 2022 Share Posted August 23, 2022 another positive of days gone by ; everything had it's own sound be it the great muscle cars, the music , and the big rigs. a Detroit 318 duel 3 1/2 pipes sounded way better then todays 8 in pipe dumps. noise is noise ; that's todays "music" and 8 in pipe trucks just noise. the sound of DD, cat, cummins ,Mack and music back then will never be duplicated by today's world. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post mattb73lt Posted August 23, 2022 Author Popular Post Share Posted August 23, 2022 TEST RUN! I borrowed one of my car phone mounts and used my iPhone as a Go Pro. A little test run video up the driveway without crashing. I think the sound is right on. Not full throttle, but probably half due to the length of the run. Everything is so tight with no play in the shift towers, yet. It all needs to get run in and adjusted. I'm happy with it so far.
