Default Looking for an odd-ball, old chevy motor...

348 / 409 chevy W motor. They were in a lot of vehicles from the 60's on up to nearly the 80's in HD truck's. I know the 409's are rare and $$$, but the old 348 truck motors were everywhere a few years ago. This is the motor I want for my 1925 TT roadster pickup project. I want a different old school look instead of the dime a dozen, put a small-block in an early ford look. Thanks.

I think my dad has a short block 409 out of a truck. Been sitting for years. No heads or intake. But Edelbrock is making those now.

Yeah, edelbrock makes a sweet set of aluminum heads.

I think HotRod did a engine build with them, and it made pretty good power.


My dad has a 348 in my moms 51 suburban, I love the way these motors look! Show pictures when you get done.

Mr. Dragster it doesn't really matter if it's running or not. I may have to piece part one together over time. I need one to at least start mocking to fab the rest of the chassis around an engine (preferrably the one I'll use). Cambird, your pretty close, your sure it's a W-motor? If so, see what he'd need for it, take it easy on me.......Thanks guys!

These motors where produced from 1958 to about 1963 and are not easy finding them. They are around and look really sweet in the old rods. Check out the junkyards especially in the warmer/dryer climates as they have usually more of the older stuff hanging around. These motors are also some what highly sought after by mostly people trying to restore period correct cars. Expect to pay there usually not cheap. I am not positive to the big trucks having these motors and if they used a special tall deck, you may want to further research this.

I'm about 99% sure it's a 409. Took it by a machine shop to have it id'd and they said it was out of a truck. Don't know what year it is. Has everything but the heads and intake. Includes oilpan, w/p, bellhousing for standard tranny and rust, lots of rust, haha. Probably been sitting for 25 years.

Right on guys, Cambird, you wouldn't happen to have some casting #'s of the block would you, don't make any special trips or anything. It may not even be salvageable if it's been outside for 25 years, lol. These engines are (should be) unmistakable full dressed w/ valve covers and such. Without heads installed the bore will have a strange looking chamfer cut into the top of the cylinder which is the combustion chamber, due to the W-motor heads being flat on the underside. For some reason people mistake 366T/427T (tall-deck truck blocks) for these motors. They were installed in big-HD truck for several years as well, mostly the 348's though in trucks. I'm cool finding a 348, I know the 409's are like hens teeth now-days! Thanks... http://www.mortec.com/wmotor.htm

Thanks man, I've got it sitting in/on the frame of my roadster project. That's a whole lotta engine, I'm going to have to stretch the frame a little. I'll try to put up a picture of the shortblock mocked up in the frame.

Thought I'd take this thread and ask a question. I got this 409 for my 1925 Ford TT roadster P/U project. I want a fairly low stance but channeling the body isn't really an option. I've pretty much decided it'll have to be Z-d at the rear, at least that's the conventional method to get a lowered ride height with an early chassis. It's a straight Model A frame and has all the crossmembers intact. I'd planned on running a 4-link and coilovers instead of the transverse buggy spring in the rear.

So, any of you fellas built an early hot rod with A or Deuce rails? I thought it might be possible to use a large C-notch located right at the end of the chassis, obviously above the differential. The kind you might find or see on a bagged mini truck w/ a body drop. Ideas? Thanks.

I'll get some pic's posted after work today. It's mocked up with a diff. under the rear now.

Draggin, I have the motor already. It's mocked up on/in the frame already. Moved this question over to chassis/suspension. Thanks.
