Right, how did we ever manage without fuel injection!!!
And electronic ignition! I remember my older brother showing me how to gap points with a matchbook cover...

Most older cars since have replaced it with an MSD module for the owner's sanity.

On GM cars I always went to the junkyard and grabbed a factory HEI distributor from a 1975 or later model car.

MSD modules are old now too. Electronic ignition kits now replace the points inside the distributor. That's what I run.

They have full on electronic ignitions now that use a distributor that communicates with a computer (ECU) where the camshaft and crankshaft are, but you control and program the advance curve on a computer screen, sort of like with modern cars. A fuel injection piece that looks like a carburetor interacts with it. They also make multi-port injection systems.

I have not used any of that (I don't own an old muscle car anymore). I have just seen it out there on the market.

Just to add my 2 cents :) ... Maybe I'm a bit too cautious. (I have an Ecoboost - it seems most commenters here probably have the 5.0) ... Personally, I'll allow the revs to come down near 1000rpm before leaving the driveway, and I drive conservatively for some time after.

I have noticed that even when the temp bar gets to the halfway mark, the actual temperatures are still pretty low - under 150F, especially trans temps take a while to get high enough to where I feel comfortable really getting on the gas.

Some days I drive all the way to work, and the temp hasn't even reached the halfway mark.

(WTF is a celsius?) 🦅🌭⚾

Start car. Put seat belt on. Plug SCT device in. Turn off traction control. Turn off TPMS warning. Back out of garage. Close garage door. Back out of driveway. Drive away normally. Let water temp hit 180 before giving it the beans (oil temp trails water temp but that's good enough)

I still remember the plug and points gaps for Pommie cars of 50-60 years ago, plugs 25 thou, points 15 thou.

The temp bar is coolant temp. It has nothing to do with cylinder head or oil temp. I wait for oil temp to hit 180 before I lay into it. But for just driving off I give it the 20-30 seconds for the RPMs to drop.

Don’t forget, the indexed and cut-back electrode plugs.

The rule of thumb is once the car warms up, the idling RPMs go down. So if it hasn't gone down yet, and it's like freezing outside, let your car warm up first. It could take a minute or two.

Your car is not even close to warmed up when the revs drop after the initial hang. It just means the catalytic converters are at the minimum of their optimal temperature range. It does this to reduce overall emissions.
