    Front suspension rebuild?

    Rubber lends a soft, cushy feel, poly is firmer, more sporty. But poly can be too hard, on potholes & dirt roads, transmitting shocks, jolts and vibrations to other parts, leading to accelerated wear & tear. Think long term: How long are you going to keep this car? Are you fixing it up to...

    Electronic Ignition , Goop leaking out

    I have successfully used RTV gasket silicone as well as hot glue gun silicone to "pot" hand crafted circuitry before. I have built several "roll-your-own" CDI modules for 1 cylinder motor scooters small enough to fit inside a pill bottle. (It's amazing how simple these are!) Once it was all...

    courtesy lights - bench seat cars?

    My 73 Newport doesn't have the floorboard courtesy lights, but I am considering adding amber strip lights under the dash (& under the rear rail of the front bench seat) to light up the floor boards to activate with the dome light. I would also like for them to come on DIMLY with the...

    Crabby Newport update

    Not to be a jerk, but regarding the AC plugs, not my 1st choice. (AC Delco is a GM brand, it seems a shame to mix n match brand names, but to each their own) In EVERY vehicle I own, including small engines like lawn mowers, weed whackers, etc., I ONLY use NGK Iridium tipped spark plugs. When...

    gas turning to varnish

    My car, Project Turd, only received 91 octane non-ethanol gas, dosed with Stabil additive (1 oz per 5 gallons) AND synthetic marine two-stroke oil (1 oz per 8 gallons). It sees a couple hundred road miles a year. I fire it up once a month for 10 minutes in winter. I live near a large lake so the...

    Engine swap should I go 360 or 383

    Cheaper to reuse original, rebuild or replace the carb, providing the 318 intake fits the 360 heads properly.

    is this joke?

    Geez, I thought the upholstery in my Newport was rough. Funny thing is, MY car was destined for the crusher. Back in 2019 I hooked up with a taxi company in Panama City Beach, Fla as a part time mechanic to maintain their fleet of taxis, shuttles & limos. We were allowed to work on outside...

    AC conversion vs upgraded system

    My car IS my retirement plan!!!

    Engine swap should I go 360 or 383

    I'd stick with a small block, less hassle, minimal to no modifications required. Even better would be a late model Magnum small block with trans and computer/wiring harness from a pickup truck, keep the EFI stock for minimal hassles. That way you get power, torque AND gas mileage, not to mention...

    What makes an engine “buck?”

    Sounds more like ignition than carb related. A misfire or preignition (knock/ping) would "Buck", air/fuel issues are usually a surge. Preignition would also cause an audible sound. But not always. If bumping the timing (retarding) makes it go away, it could be carbon buildup on the pistons, head...

    Airr shocks & traction bars

    I was going to suggest Caltracs as well. That's one of the items on my wish list. They don't just aid in straight line traction off the line or only prevent leaf spring wrapping, they positively lock down the rear axle, preventing twisting or torquing while still able to articulate up & down...

    Does a tightly shaking vacuum gauge REALLY mean an ignition problem? Chasing my tail.

    No, but ethanol blended fuel wasn't widely available when our cars were new, therefore they weren't "hardened" against the effects & damage ethanol can cause. Such as water condensing in the fuel, dry rotting all the rubber lines from the inside out, and leaking rubber & neoprene seals in the...

    Shaking!

    Yeah, reading this, I was thinking drive train imbalance too. You replaced the rear U-joints but not the front, my recommendation was to replace the front U-joints first and see if it doesn't solve it. Of all the possible culprits, that one is the easiest and cheapest to fix and unless it...

    Does a tightly shaking vacuum gauge REALLY mean an ignition problem? Chasing my tail.

    Honestly, if it IS a fresh rebuild, a compression reading like that is indicative of cylinder rings that haven't seated yet. It takes anywhere from 500-2000 miles for rings to fully seat, depending on ring thickness, materials, and the degree of cylinder hone. On top of THAT, that excessive ring...

    Lowrider 1970 300 convertible

    Love it or hate it, SOMEBODY saved this from the crusher/fields of broken, shattered dreams (junkyard). That in and of itself is something to be proud of. Our C Body land yachts rarely get much attention or respect by the larger automotive community. For someone to languish this much detail &...

    My neighbor ruined my plans

    If it were me, I would take the Imp to get SIX different body shops for estimates, (pick the top 3 for the judge), with quotes for turn around. Because this was your daily driver, you will also need a rental car while waiting to get the Imp back, hence the need for a written timeline. Then...

    Trans upgrade

    Honestly, why NOT consider a gear vendors under/overdrive? It has two modes, automatic where it'll shift into OD on its own at 50ish, and manual that allows you to split shift ALL the gears, basically giving you a six speed close ratio trans. Tach it up to 4500 in low, and toggle the gears, 1st...

    Cowl fresh air venting

    Pine needles are the worst! They can and do get thru the cowl screens and are highly acidic, as they break down they greatly contribute to rust. That's why you don't see green turf grass under pines, the soil is too acidic from all the fallen needles. My answer is either park indoors or a car...

    Low rolling resistance tires (LRR), my experience

    The very name, "Low Rolling Resistance" implies less traction. I am assuming to achieve that, manufacturers use a harder rubber compound, stiffer sidewalls to minimize flex and a smaller contact footprint, and higher air pressures. I have my suspicions they are being used for EVs in an attempt...
