Yeah, that’s the catch-22. On start-up, an engine wants 1) hot air to help vaporize the fuel and 2) excess fuel. But of course an appropriate not-too-rich AFR and cold / dense air is good for power on a warm engine, though the air still has to be warm enough to vaporize the fuel properly. In...

The factory service manual mentions it’s full on at 10F and full off at 100F of air temp. Between those temperatures, it blends. “The quantity of air through each circuit is controlled by a heat control door in the snorkel so as to maintain a temperature of 95 to 105 degrees at the temperature...

Yes, I see that now. 9A-2 (pg 552): "A vacuum hose connects to a hose nipple on the base of the carburetor and leads to one side (either side) of the sensor and another hose connected to the opposite side of the sensor and leads to the vacuum diaphragm on the snorkel." So... I assume when they...

Trying to reconnect the thermostatic air cleaner system so it runs better when cold (1971 Valiant). I have a freshly-rebuilt Carter BBS: there are only two small vacuum ports. The ported one which goes to the distributor advance and the other for the choke pull-off. There are no other small...

Yeah, turns out it’s relatively common. The dipstick passes really close to the crankshaft, so if they are even slightly bent in the wrong spot the crank hits it. Not a great design.

Found it! Pulled the dipstick and the noise went away. No amount of bending the dipstick or putting it in a different orientation changed it, so just left it out. Dumb thing! Anyways, the thin flimsy bellhousing cover is off since that was rubbing too. Can I leave it off? Is it really that...

Yup, when first started it was making a terrible racket and I suspected the bellhousing cover. Removed it and that noise disappeared, leaving this other less severe noise. So is the bellhousing cover even necessary? I don’t drive it a ton - rarely in the rain and never in the winter.

Yeah, 198’s are kinda cool and different. Needed to get it back up and running ASAP for the Woodward Dream Cruise and swapping in a 225 was easier and faster. Also, 13% more displacement never hurts :) And the ‘76 we got has hardened exhaust seats so that’s a plus.

Torqued them all to 22 ft-lbs per spec. Yes, the long rods are desirable, I do know. Any idea what a set would be worth? I was just going to sell the whole engine and let someone else dig them out. Don't have a ton of time right now.

The original 198 in my '71 Valiant lost cylinder #6, so we found a decent '76 225 and swapped it in today. Mounts were different and there was a bunch of additional emissions stuff which we removed, but otherwise went pretty darn well! These engines are so straightforward, love it! Anyways...

I literally just installed NGK ZFR5N (#3459) a few days ago. As mentioned, they are extended tip and get the spark closer to the center of the chamber, which is desirable. I also have the HEI conversion, so I gapped them a bit higher in the 0.036-38" range (and you can certainly go higher). Runs...

This happened to me as well, shortly after I got my '71 Valiant last summer. Turns out the Holley 1920 had a small crack near the accelerator pump. When you stepped on it, it would leak gas out the carb onto the intake manifold! With the gas not going into the engine, it obviously leaned out and...

Yes, you just push the wire through the boot, cut the insulation back, fold the wire back over and crimp the terminal over the end. I would still try to find a "professional" made one at some point, but it should work no problem for quite a while.

Yes, there is a way. As you already know, the HEI module that comes on what you got is looking for a digital signal (square wave). The Mopar distributor puts out analog. No problem, just get the Delco D-1906 HEI module. You can get it on Amazon for about $30. You'll have to grind off one of the...

Hey Dan! Thanks. I just reached out to Aurora. Hopefully I'll have better luck. Magnecor hasn't responded after multiple attempts. It seems odd to me, many people have converter mid-90's HEI's to MOPAR's or other cars with socket caps. I'm surprised there isn't an off the shelf solution somewhere.
