Has anyone attempted to put a 348 or 409 motor in a 55 Nomad. I like the look of the motor, will it fit without major modifications. I have a 57 283 in it now and thats the only non 55 component. I'd like to keep it original looking but don't mind the look of an original 348/409. Thoughts?

Tom

I did a 348 swap into a 55 a very long time ago. It was definitely not a drop-in. I had to move the engine forward to avoid hitting the firewall. This meant I lost the stock bellhousing mounts, so I used a Hurst saddle mount at the front and added a crossmember for the trans. Because of moving the engine forward, I also needed a longer driveshaft and had to cobble the clutch linkage. In addition, I had oil pan-to-center link and exhaust-to-steering box interference. The radiator just barely cleared in the 6 cyl position.

This was long before BB swap kits were available, and those might address some of the clearance issues I ran into, but of course they wouldn't help any with the 348 exhaust.

If you feel up to dealing with the clearance challenges, I would still recommend doing this swap just so you can have an engine with more eye-grabbing appeal than a belly button SB.

Someone dropped in a 396 in my '56 Nomad before I bought it. They hammered in the Firewall some to make it fit. When I bought it, I went back to a Small Block. Although they make kits now (for BB's anyway, not sure about W's), I would still keep it SB, in my opnion anyway.

Thanks for the insights Ray. I sure like the way the 348's look. By the way, I think we meet once and I've seen your car, 55 with a Waldorf conversion.... sweet. I lived in Danville, CA for 20+ years and spent a lot of time at the local SF Bay car shows & Pleasanton GG shows.

That's an uncommon swap, but I would go for it. There are tri-fives out there with W motors in them. Locally there's a '57 with one in it, but I don't know the specifics of the swap. So there should be a fair amount of info on the swap out there.

Sorry, that's not my 55, but I think I know the one you mean. My current project is a 60, and of course it has a 348.

I did this with a 348 some 45 years ago and Ray is spot on. I think I still had to dimple the firewall a bit on the passenger side. I made all my mounting plates and had a 3 speed /overdrive behind it. I got mid 20's for gas mileage when I could keep my foot out of the gas and power to spare. The WOW factor when you pop the hood is totally worth it.

I bought a 55 HT that had a 348 using the stock rear mounts and new holes drilled in the frame for the front mounts. That was in the late 1960s, and I don't remember if the firewall was modified for clearance. It was very cool and had a stock 3 spd.
