Finally back on the car. Sorted out the gas gauge, installed a relay for the electric fan, tidied up some other wiring, swapped the trans pan for a cast one so NO leaks now - progress! Tried to start her up a couple of weeks back, and it ran on maybe 6. WHAT? Somehow, while sitting for a few...

I’m still waiting to get the kit to adjust total timing which is clearly needed of course.

I think the issue of idle is largely solved. I guess I should have mentioned that I have a 4 hole spacer, but I didn’t notice much of a difference with or without. It should help heat soak though. I also checked the vacuum passages under the carb, and Geoff is absolutely correct, there are no...

thanks! I ordered the keys and springs, will be delivered in a few days and I’ll report back.

Thanks! So you’re suggesting total mechanical advance at 34? I’m not racing, just cruising (or more accurately, wrenching! One day…). Mainly I don’t want to be throwing gas fumes out the back so bad nobody can breathe near it! Right now I’m in the middle of swapping out the bent, leaky trans...

Thanks! Doug, I appreciate your analysis, no need to get all twisted up about it! I already said I’m going to address it, but surely the best way to learn is to ask?

Just to add, there are a bunch of posts here and other forums stating that 42* total is fine. Such as this one Post in thread 'Setting the timing on a 383' Setting the timing on a 383

I will certainly check the total timing. It’s a pain to adjust, but as I said I was working on the idle to start. Leo, I’m not sure what you’re saying about the carb? It works fine, all passages clear, float height correct etc. The plugs are equivalent to an NGK 5 heat range. I’ll get the...

Hi! Reporting back… First, I made a mistake. It’s an Edelbrock 1407 which makes it 750CFM, manual choke. It does have heat range 6 plugs already, I use Champion Copper. I used to use NGK in everything but think they’ve gone downhill. I did some tweaking this morning and have some good...

Thanks! I checked the wiring from the distr. to the 6AL and polarity is correct (unless the distributor is manufactured incorrectly). I will indeed mark the balancer to get a more accurate assessment of timing and report back. interesting that 30* of initial is ok, then I guess I need to make...

1405, so 600 with manual choke.

Big-A, do you mean that 30+ at idle is ok?

I have no idea if the cam was degreed, I bought it as a badly running project. I’ve sorted out a lot of issues already, now down to this. i think it’s rich at idle because the plugs are black and it stinks when idling. It seems to clean up as it’s revved. It does idle, yes, but it’s very antI...

About 5PSI, it’s not throwing extra fuel in, I can see the check valve stopping fuel. It’s a stock (and new) type mechanical pump. Also float levels are fine, checked a few times!

Motor is a 383, believed to be a ‘69, in my ’66 Coronet. - Jegs distributor, looks like a clone of the MP one with a magnetic pickup and vac advance. Default light blue springs and I haven’t touched the vac advance. - Unknown “Purple” cam, but probably the MP 268/284 (they seem to have...
