Well, the new carb and intake have been put on pause. The muffler blew up during a hot-start last week, a friend actually heard the explosion from a kilometre away. Now I've got the car booked into an exhaust shop, I'm taking this chance to upgrade to dual 3" mandrel bent stainless. It's...

Thank you for those additional considerations. As for the height clearance, I was somewhat planning on swapping to the air cleaner from a 400, which should be 1" shorter. That combined with me not having hood insulation should provide enough clearance. I'll measure things to confirm though. As...

I was initially concerned about what the police would think, but after driving past 6 of them with no reaction, I think I'm likely in the clear. A couple more things popped up with the car that'll need to be addressed. The first being the power windows. There's been times where none of the...

So I tried again, and the new starter bolted up with no problems whatsoever, I didn't even have to do any grinding. Now the engine finally cranks fast enough to start the car in cool weather! Additionally, my rear drum brakes are giving me trouble, I think this summer I'll convert it back to...

Here's the horsepower/torque curves for a '77 NYB with either a 440 or 400 (courtesy of automobile-catalog.com). As seen here, the 440 would have more low end torque, but the 400 seems to catch up after around 3,000RPM. The factory power specs are tuned for emissions compliance, with lazy...

Thank you, I've heard for a lot of people that it's a drop-in replacement, in the sense that there's no grinding required, other people say that there is significant grinding required. Is it pretty much based on excess in the block casting? On my (now broken) starter, I found that the plastic of...

I need some help with mini-starters. The original starter doesn't crank fast enough to start the car in colder weather, so I've decided to upgrade. I bought a new mini-starter from RockAuto, but it didn't fit and ended up breaking while I was torquing t down. The Problems: -The top mounting...

Thank you! As I've converted my Imperial to rear drums, I wouldn't need the extra capacity. I was more so wondering if the functionality/valving within the two were different. If I were to follow through with this idea, I'd have the original Imperial master+booster rebuilt, then reinstalled...

I've ran into that problem on my '78 Yorker. Unfortunately these cars are pretty much non-existent when it comes to reproduction and aftermarket parts, meaning he'll likely have to find a parts cars to cut them out of, or fabricate his own

That's a question better answered by somebody who has a parts book. If you can't find it through any of the major parts stores, you could probably get a used one pretty easily. I personally wouldn't even bother putting it back on, the whole EGR system is needlessly complex and the cars seem to...

I don't believe anybody makes either, unfortunately. Windshields are normally sourced from parts cars, any '74-'78 C-body hardtop should have the same windshield. For weatherstripping, it's more likely to find it on a parts car, but there are a few places that still have N.O.S stuff in stock...

That is an EGR time delay controller

The seller likely just google'd "How much horsepower does a 440 make?" and got the response for a '60s spec engine. $16,000 seems steep for a sedan, but it's good that these formals are getting the recognition they deserve

I was unfortunately unable to find a complete build sheet in this car, they seem to all have been previously removed or destroyed by rodents. I was, however, able to find an "Electrical Build Card", which I hadn't even known was a thing before finding it. I also got a picture of the fender tag...

That makes a lot of sense, thank you!
