Engine options to put in 67 Dart GT convertible

As 65Val said. Any small block would do. 318's are dime a dozen, usually can pick up a running one for free. Around here at least. If you're lucky, might get a tranny with it. A stock 318 though is more than likely going to be a dog. And honestly probably will only match what you've got now in power. You might luck out and find a 360. But with little or no budget it won't be great, better than a 318 but not by much. It's at least a good base though. As for 340? Around here super rare, always wanted and usually still in some guys car. I see guys selling 340 shortblocks for way more than they are worth, just cause they are 340's. 440 out of a motorhome is an idea (think roadkill). I've seen them already pulled for under 1g. Even a dog 8:1 440 still makes power. But it's a heck of a lot of engine to stuff in that car.

Upgrading the slant is always an option. You'd be surprised what you can do with it. While keeping reasonable mileage and decent handling. You don't mention what you did when you rebuilt it. One thing to look at in your current setup. What rear gears are you running? A lot of the old 8-1/4 did not have fantastic gears. A lot in the 2:? area. I had a truck with a 2:76 and the thing was a dog in the city. You might already have a good base to work with and it just needs some tweeks!

As a third option, and something that's actually fairly reasonable for what you get. Have you thought hemi? 5.7's are more and more available. Wrecked trucks, cars, etc. The engine has been out for 10 years now. They are starting to fill up junk yards and such. I can find a running good condition one around here for 1,500 or so. They will basically bolt up to any transmission that bolts to an LA. So not a lot of worry there. Granted it is "more" money than finding an old LA and dropping it in. But you know what you're getting with it.

One thing I'd do if your strapped for cash. Is see if there are odd jobs and such you could do for members of your car club for help/parts for your car. A lot of guys are more than willing to help a young guy out, especially if he shows interest and initiative. I don't know if you are able to work a job during school. But even a day a week can bump up your budget.

Just some ideas for yah!
