The Stovebolt Site Forums The Shop Area Engine Shop A Nova 250 in an AD truck?

Guys, I have access to a good, inexpensive 250 out of a 196? Chevrolet Nova.

Should I be interested?

Is it a bolt-on in my AD?

I dont need it, but than again (as my wife would say), it never stopped me from buying anything in the past...

Hey Whizz, long time no see! Hope all is well in La Belle Provence. The later inline sixes (like your 250) aren't a "direct bolt in" for an AD, unfortunately. The main issue is mounting. The later sixes mount to the sides of the engine block and transmission tailshaft just like a smallblock V-8-so you've gotta change the mounting system. I'm sure some other fellas here have pulled this one off and could offer some tips. I read in one of mothertrucker's Gallery submissions that one of his trucks had a later 250 in it-you might want to drop him a PM. Hope this helps, Rick. Wishing you and yours the best of the holiday season,

If it's an early to mid 1960s Nova (through 1967), chances are good that the 250 is actually a 230. Be sure to run the casting #s to make sure you're getting exactly what you pay for.

Tom Langdon at Stovebolt Engine Co. has weld-in mounts for that application. I don't have his # handy, but there's a link to his website on the banner on the Inliners home page.

If you do get it in there, you could make it scream pretty well with some mods. Easier than a 235. If that's your intention of course.

Whizzer - Like they said, it's not a bolt-in, but shouldn't be that tough. The block is narrower and requires special mounts. I think Landgon's Stovebolt has them. Also, be sure to run the numbers. The early Nova's had a 194 as an option to the 4 banger. The 194, 230 and 250 share the same block. Inliners.org probably has more info, and does have a good number chart.

I think the pre-80 250 six is a good motor, for what it is. I had 2 in the past. It seems to be a favorite of the good folks at inliners.org. That's another thing, each website/forum/vendor seems to have a favorite. Patricks loves 235s, and it's real popular here on the 'bolt page. It would be much easier to put in your AD than a 250.

One more thing. If the engine has the integral head/intake manifold, you will want to get a different head and manifold. This was one of those good ideas for less maintenance, but they are not made for performance.
