So I'm experimenting. I like loud exhaust from my vehicles, especially the flathead sound. I have the mufflers removed at the moment, and it sounds killer at idle, but sounds choppy under load. What are your thoughts on this? It had glass packs on it, but was practically silent. Is there a very small muffler to help with resonating sound?
Glasspacks with full exhaust pipes to the rear, 1-3/4" pipes, are as good as it gets. They typically sound very throaty under load, and resonate around 1600 - 2000 RPM. Above that at cruising loads, they are not that loud.
Just buy the shortest glass pack you can find.
Flowmaster makes their 40 series mufflers. They produce a nice sound in newer engines. I have never knowingly heard them on a flatty. They would have to be necked down too. I think the smallest pipe they offer is 21/4 inch.
Awesome, I'll take a look for one. Also, off subject, any idea where to get motor mount bolts for 239? Appears that the last person to touch mine, stripped them
You can get motor mount kits that include bolts. Here is one vendor that offers the kits, I know there are many others. Just use the part number and shop around: Ford Motor Mount Kits - 78-6038-BDK - C&G Ford Parts
The bolts for a '52 are about 1/2" longer than the others. Some of these suppliers are showing them the same, but they aren't. I need the upper and lower mounts for my V8, but even the Balkamp mounts I saw at NAPA for the earlier trucks are made in India. Can anyone recommend Carpenter or any of the others as being made well? Those Balkamp mounts looked like poor quality rubber, but maybe they're OK? - Bob
I didn't previously realize that 52 truck motor mounts were a one year deal. I wonder why Ford bothered? I also wonder if the earlier mount would just bolt in since the catalog shows different rubber and bolt part numbers.
I was a bit disappointed in the quality of the motor mounts I put in my 37 sedan. As far as rubber mounts, I suspect everyone is selling the same made in India rubber mount kit. I have heard that the polyurethane mounts are better but I have no experience with them. This one is at least about the same price as the disappointing rubber mounts: Motor Mount Biscuit Cushions Ford Flathead SBC Chevy Street Hot Rat Rod Engine | eBay
The rubber in Carpenter's mounts are (were) made in India, too, at least when I bought them 10+ years ago, can't say about the bolts and hardware. They are very simple cushions, fit perfectly. No problems with mine. Carpenter's trans mount is (was) likewise Indian, and the rubber was cast right over the mounting holes. It took a lot of work to cut away excess rubber to be able to mount it. But it has held up well too.
Do you have the NAPA p/n? I'm not seeing them.
PS -- I'd avoid the urethane, based on experience with other applications
Fred, the '52 is different because of changes to allow use of the new OHV 6 cylinder - there are illustrations in the Truck Parts Manual that show some of the differences. About 30 years ago I bought a set of mounts for a '47 Coupe that I owned - they were imports and after about a year they cracked badly and started falling apart - had to put the originals back on. I believe they came from an antique Ford parts place called Rick's.
Ross, the numbers for the NAPA mounts are BK 6021177 and BK 6021178. Those are for '51 and earlier. They don't look much like the ones on my truck, but possibly could be used. If your '52 mounts from Carpenter are still holding up, I'll probably take a chance on them. I had one of my mounts off last week and took some pictures. Can they be posted here, or do you have to store them somewhere else and link to them? - Bob

Thanks, Ross - hope the pictures work. One shows the front motor mount off of the truck and the other shows it in place. To keep on topic, the new exhaust pipe that I built last week is shown. I run a single exhaust with a glass-pack and and a "turn down" tail pipe just short of the rear axle. It rumbles a bit, but hearing the engine speed helps to shift the 4-speed. - Bob
