    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Currently at home in northern Virginia, but go to school in Radford so I’m almost at the southwestern tip. 2 hours from school on a good day? 81 is 81 so it’s a turkey shoot lol.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    That is with the 66 jets I haven’t yet changed anything internal. Does that mean it kind of invalidates the idea of changing the jets back to stock?

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Gap is 35, same plugs as came stock and what dodge recommends. I usually do yeah, when I don’t I have dieseling issues but the booster works well enough. The current tank has no booster however, 87 octane.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Here’s a plug from cylinder #1. My alternator is also charging at 14.9 according to my $4 Walmart multimeter.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I found one from ACDelco off of good old rockauto that’s 120 so I’ll probably end up with one of those. I’ve had nothing but bad luck with reman. Alternators so I’d like a new one if I can find one lol

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Yeah my voltage gauge drops when my blinkers are on lol so I’m sure part of it is a bad ground, but doesn’t hurt to check. I think I’ll be getting a new alternator anyway because I want to run dual batteries with a beefy inverter (it’s a work truck but not slow is the goal here).

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I’ll check voltage again in a minute, I’m going to go pull a plug and take a peak. I really only get alternator issues at idle, once I’m driving it’s fine. I notice the headlights and dash dim and the voltage gauge drops down but when I’m moving it’s where it normally is.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    About 13.6-13.8. My alternator is going out though so it fluctuates a lot, I’ve had this issue prior to doing the engine swap just have been bouncing between getting a HD alternator or stock replacement. Also can I have reasons why people say don’t use a mechanical secondary carb on a street...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    So does it make more sense to run the VA on ported vacuum or manifold vacuum? Or is that really dependent on how the engine reacts to each?

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I mean when it’s hooked to ported vacuum, or “timed vacuum” as it’s called on the diagram. It’s the port that gets the same Venturi as the jets I believe? Manifold vacuum decreases under load but Venturi “vacuum” increases does it not?

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I have this picture from after quite a bit of cruising with the #66 jets, still with 14 degrees of timing. I’ll take another picture once i get back from the store. I drove over to Lowe’s with the timing set at 10 and it feels a little peppier off idle but it’s significantly less quick at WOT...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Alright well that’s a start lol. I guess I’ll have to order a throttle cable kit and flip the carb around. Do you guys think it would be worth getting a manual choke? I know those aren’t reversible once installed. At least from what I can tell with the lead ball.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I didn’t really think that the orientation mattered honestly, I mainly did it this way because I wanted my fuel line tucked against the firewall and wanted to retain the stock throttle cable for time being which was routed the same way it is now, around the front of the engine to the passenger...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Here is the startup video. Ignore the ticking, it’s a pushrod issue and I have non adjustable rockers

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I had it set to full manifold as opposed to ported from suggestions from a couple of people. I believe the can pulls about 26 degrees at full vacuum. It’s a MSD chinesium clone that didn’t specify. I need to take a peak at it once the engines warmed up. It did fix my off idle stumble when it was...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    The AFR numbers I listed were "goals" I was asking for opinions about if those were safe numbers, I should've specified that lol. I'm about to go out and take those pictures for LO23M8B just have to let the truck roll down the driveway a bit so I don't smoke out my house haha. I've set my...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    If I recall correctly it’s currently set up as it was stock. Set to be fully open at 72 degrees according to the manual. I’ll take some pictures later today when it warms up a little more outside and I go to tinker with the timing.

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Yeah I plan to get a wide band in the next coming weeks and use that for tuning, I was just curious if there was anymore useful input with my current situation. Do these numbers sound pretty good for AFRs? WOT: 13.0> Cruise: 14.5-15.0 Idle: 15.0 I've been basing my jetting off of what the...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    I think I got my carb names mixed up lol oops. Anyway, I started messing with the timing and Idle mixture first, I tried 10, 12, 14, and nothing made a real difference. Timing is all in 31 degrees at about 2800, I haven't messed with the curve yet. I then went to the jets as I was burning...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Holy cow that's a lot of information to digest lol. I guess I'll add some more information if it helps you. I have the AX-15, geared to I believe 0.79OD, stock tire size 235/75r15 @ 41psi, and 3.55 gears which brings by 65mph rpm to actually probably about 2200. At 70 I'm at 2300. Vacuum...

    Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

    Hi all, First time posting on the forum, I was posting on DodgeForum but was pointed here by another member as the first gen Dakotas are mainly EFI, and this forum has more knowledge on carbs. I've been chasing a couple of issues but wanted to get some final input to help me fine tune my carb...
