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

    Haven't checked but the idiot light works. Also the battery is always charged and it starts no problem. I usually run my lights but wouldn't the battery show weakness if that were the case? Funny, when I do any driving or acceleration I don't feel a misfire, just that cyclical vibration I've...

    Intermittent and above idle. Carter 4 barrel original.

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

    I've had the distributor apart and everything looks great, just checked the wires and plugs, compression is 100psi across the board, carb is rebuilt, looked closely at the distributor cap and it looks new, but still has an erratic miss at cruise or still at 15-2k rpm. Only other clue is the...

    Should I have used new unused plug wires that are 10 years old?

    I checked all of them and most are 2 feet long and measure 8.5-9.5k ohms on the 20k scale ohm meter. Longer ones at 2'7" are around 10.15-10.70k ohms. Does this sound correct? Thanks!!

    Should I have used new unused plug wires that are 10 years old?

    Do they deteriorate over time even not used? These are on my 57 Belvedere. What's the official resistance per foot for 7mm Prestosil Class E suppression cable?

    rebuilt 301 vibrates at around 3k RPM or 40 mph

    No, nothing happens at idle when I remove it. Only above idle does the timing advance more when I reconnect it.

    rebuilt 301 vibrates at around 3k RPM or 40 mph

    It's ported at the base of the carb. I know this because I hooked the vacuum gauge to it and only shows vacuum at higher rpm's.

    Mystery brake issue.

    My first thought would be to remove a bleeder completely and see if it's partially restricted. Also look in the hole too. The crud and corrosion is the clue.

    rebuilt 301 vibrates at around 3k RPM or 40 mph

    Thanks CBODY. The problem is more in the 2k rpm and above and the dwell was off about 2 degrees at about 33 degrees. I adjusted it to 30 degrees at idle and it moved to 23 degrees at 2k rpm or above. The advance seems to be working as it drops about half of the advance timing off when...

    rebuilt 301 vibrates at around 3k RPM or 40 mph

    I've determined it's the engine at around 3k rpm when car isn't moving. I can feel it misfiriing at about that rpm and creates a repetitive vibration. Could carburation cause this or the distributor? It's at cruise and not hard acceleration.

    This rubber trunk mat available for my 57 Belvedere?

    Sorry, those are the two high #'s 110 psi. the rest are 100 psi.

    2 similar cylinders are #4 and #7. After reading my old posts you sent me (thank you), I need to wait another 500 miles or more to check compression again.

    This rubber trunk mat available for my 57 Belvedere?

    Yes, I think about 60 pounds heavier.... Thanks 57, I posted a new thread to find out. People are anxious to mention what they think, but I want to see from actual owners of the 301 to find out. I've got a 68 GTO 400 engine with a cam and the psi #'s are 120 a cylinder and it goes like a bat...

    Anyone else that has checked their stock 301 compression in PSI?

    Mine are pretty even at 100 psi.

    This rubber trunk mat available for my 57 Belvedere?

    Unknown, I bought everything with the rebuilt engine out. I can see the original cam and pistons have not been replaced, but it's so clean inside (it had to have been boiled out and totally taken apart) that I figure they did what any reasonable person would do and that would be to spec it and...

    Is your engine a 301 or 318? Not sure if that makes a difference but after 500mi break in I adjusted the valves and took a compression test. They're all 100psi except for 2 that are 110psi. What are yours in psi? Most people say that's low so I wanna get it from the horse's mouths (you and...

    This rubber trunk mat available for my 57 Belvedere?

    Pictures complement a car. My car is pretty banged up too. One fin has bondo and the color match looks bad now. Also the drivers front fender or door must have been damaged because you can see an attempt to blend the paint which has orange peel. I rubbed out all of it and it looks ok but the...

    This rubber trunk mat available for my 57 Belvedere?

    I bought this from the 70 year old grandson who's grandfather bought it in about 1960? It's been a bay area car for most/all of it's life. I just wish I could get all those service records that are gone. The odometer says 72k miles which is probably true.
