    1974 Valiant Scamp 318/904 feels sluggish

    I put it all back together with a new power brake booster, runs great now:

    1974 Valiant Scamp 318/904 feels sluggish

    I finally has some time and decent weather after the holidays to dig back into the car. I tried tuning the carb but it was all over the place. It wanted to be super rich on the passenger side mixture screw, and still seemed lean. I started spraying some carb cleaner around the intake and...

    Graveyard Carz

    I love the show, the history and historical accuracy of their builds interests me a lot. BUT, and I know it sounds weird coming from a 28 year old guy - his daughter adds nothing to the show. I don't mind giving her a chance to learn, if she actually seemed interested in cars. By all means I'd...

    Lets see your cars.........

    This is how I want my Scamp to sit. I saw from your garage journal it has SS springs? What size tires are on it? I like the tall height "tough muscle car" look. Mine sits so low it reminds me of the old Cadillacs.

    Lets see your cars.........

    My POS 1974 Scamp. I think it's just tired and wants to be a parts car, or get recycled into cans.

    1974 Valiant Scamp 318/904 feels sluggish

    It's a stock long block as far as I know. Don't have the tools here yet for a compression check, but it is a new motor, something like 17k miles on it. I put the silver springs (8") back in and it gets up and goes pretty good for a stock 318 when I go WOT, so I am going to step back down to the...

    1974 Valiant Scamp 318/904 feels sluggish

    I have been working on a 1974 Scamp that I got in a trade, the car has a ATK DD03 replacement longblock, Edelbrock 4bbl 1406 and a rebuilt 904 transmission. So far I have: Rebuilt the 1406 with stock jets and rods, set t-port sync, installed orange springs (5" HG) Installed a new distributor...

    Oversized front and rear windows?

    Sorry they are Lexan, and they are oversized by 1" on the perimeter. I removed the chrome/stainless trim from the windshield, rear window, and drip rails. I found tons of dirt, leaves, and mud caked into the backside of the trim and in the channels around the window. Plenty of rust to deal with...

    Oversized front and rear windows?

    I have been looking into oversized windows for my Scamp after I pulled all the trim off. I was never a fan of the large trim around them since they just seem to collect debris and cause rust. Does anyone know if these are made or where they could be purchased? I saw that Optic Armor seems to...

    LSA or Duration to fine tune glasspacks??

    I rewatched the video and I definitely get the thip vs the thap - milled heads as much as possible, stuff in a big cam, you'll get tons of thap! I think you are going to want to mill the heads so you can bump the compression to something closer to 14:1 and run as much duration as you can. My...

    LSA or Duration to fine tune glasspacks??

    These are cheap thrush glasspacks on my cammed 5.3 '89 Formula. Terrible muffler, but the previous owner put them on to get by. I have LTs and a SLP Loudmouth going on it. If you are determined to go with a "glasspack" go with a Borla XR1, Dynomax bullet, Magnaflow, SLP, etc. All they are is a...

    1974 Valiant Scamp, timing retarding when revved

    Well the car is back up and running. I finished rewrapping and looming the engine bay portion of the wiring harness. I also did a fleet bypass. 2AWG wire from alternator stud to the battery directly, 2AWG from battery to starter directly, then a 4AWG to the relay, and a 4AWG to a distribution...

    1974 Valiant Scamp, timing retarding when revved

    Hopefully minimal, it was rebuilt before I got the car about 17k miles ago. When I had it running, shortly before I ripped the pickup wire in half - timing was steady and I didn't get any erratic readings. Once I finish up the harness, fleet bypass, and feel safe driving it, it will be getting a...

    1974 Valiant Scamp, timing retarding when revved

    That's good to know, I was afraid it was beginning to overheat. I bought two new ones, a Mopar Orange/blue box and some off brand box. The Mopar box has the same sticky gel like packing in the back of it while the off brand has an epoxy fill. I wonder if it would be ok to fill the old one with...

    1974 Valiant Scamp, timing retarding when revved

    I probably just imagined it honestly, it ran horrible when I got it and all I had was a cheap HF light. I think I just caught it going ATDC since idle was set at -5* and it stumbled, choked and stalled off idle. so every time I caught the mark with the light it looked like it was going the wrong...

    1974 Valiant Scamp, timing retarding when revved

    Timing is no longer retarding, correct. AJ, thanks again, and that will be the first order of business here in the next day or so. I pulled out the harnesses from the bulkhead connectors and I'm working on rewiring and looming them all. While working in the bay on the distributor and wiring, the...

    1974 Valiant Scamp, timing retarding when revved

    Here is a video of it while I was testing a few throttle stabs and seeing if it would idle in gear. I messed with the idle mixture adjustment to get it sounds right at idle, but I think that threw it off in gear. I think I'll just have to reset and start over with the mixture screws, and then...

    1974 Valiant Scamp, timing retarding when revved

    AJ, it runs great after setting the transfer slot as you said. I get a fairly smooth idle at 850rpm just adjusting the idle mixture I can put it in drive and it idles at about 750rpm with 12" of vacuum, on 10* of spark advance. I think it could use more fine tuning but the baseline is set, I...

    1974 Valiant Scamp, timing retarding when revved

    We are on the same page now, I get ya! The transfer slot, or how much of it is exposed on the underside of the blades. I pulled the carb when I got a break from the rain and set it at .030 using a feeler gauge. This is the timed vacuum port side, as you said it's not exposed at all when the...

    1974 Valiant Scamp, timing retarding when revved

    Yessir, I read over it. What I'm having trouble translating over the the edelbrock between your directions and the manual are these two steps "2)With the Curb-idle screw,set the t-port exposure under the butterflies,to about square to rectangular,or .025/.030 high. 3)Set the idle-speed with...

    1974 Valiant Scamp, timing retarding when revved

    I'll give it another go tomorrow if the rain lets up. I'll try lowering the idle speed screw a bit more, I tried earlier and it lowers the idle, but I can never get it back to the 750RPM spec, regardless of how I change the idle mixture screws - light still shows right at 10* initial timing all...

    1974 Valiant Scamp, timing retarding when revved

    AJ, I went and bought a timing light with the RPM function, super handy for this! The timed vacuum port has no vacuum on it at idle. Spark is solid at 10* advanced at 750RPM idle, 16" of vacuum, with or without the vacuum can plugged in. I then set the mixture screws to get the best idle...

    1974 Valiant Scamp, timing retarding when revved

    I installed the rebuilt carb and it runs much better. After that I set timing to 10* BTDC and idle speed picked up a LOT, I dropped the idle back down using the idle screw and then set the mixture for max vacuum, backing off a 1/4 turn. However, now when I put it in gear it stalls out. Restarts...

    1974 Valiant Scamp, timing retarding when revved

    I'll check the wiring there too, but I seem to remember it had a specific way it plugged in. The other portion of the harness could be backwards though, that has been spliced at some point. The only time I had it idling well enough to try and get the base timing off it, it was at 5* retarded. It...

    1974 Valiant Scamp, timing retarding when revved

    It looks like both the voltage regulator and ECU are doing that. I'll get some better pictures as I unwrap the electrical tape abyss that is the wiring harness. It's a marvel it didn't burn down before it made it to me....I even found wire nuts like you'd use for home electrical stuffed under...

    1974 Valiant Scamp, timing retarding when revved

    I just rebuilt the carb with the stock 98 and 95 jets last night, the tuning kit should be here tonight with the new springs. I will give the carb a try, set the timing, and fueling. I'll also take the fan off and try it, the shaking really is what bothers me. I hope it's the carb, but it...

    1974 Valiant Scamp, timing retarding when revved

    I also pulled the ballast connections apart last night, which was a bear without breaking it. They are heavily corroded and were starting to melt. If rebuilding the carb and cleaning up the ignition connections doesn't clear it up, I'll just pull the entire front harness and go through it for a...

    Correct, pickup is secured and set, timing is still going backwards though.

    1974 Valiant Scamp, timing retarding when revved

    I haven't been able to get to the bottom of the timing issue yet and feel like it may be partly due to a poorly set up carb. Once it warms up I can't put it in gear without stalling, got myself stuck in the middle of the road for a bit...that was fun. It is an Edelbrock 1406 with what look like...
