426 Wedge possible install challenges

A 360 is more easier on pocketbook. visually and fit-wise identical to a 340. And a little bit more torque for a convertible cruising machine.

A 340 block open market will cost $800 or probably more than a comparable 360 block.

So motors you would buy in whatever stage long block, short block, carb to pan will reflect that difference. If you were having the motor built, that $800 extra would pay for the upgrade to a stroker 360 with 410 cid.
Located a fresh built 360 short block that was removed from a 78 cordoba. Stock crank and connecting rods with 9:1 pistons, new comp cam flat tappet and lifters, cloyes timing chain, Melling oil pump $850 CAD. Ready for any other goodies. Dart already has 8 3/4 rear end, I kept the mini starter off the 273 that was originally in there. Cooling is already there for the small block setup and I'm pretty sure the 360 will bolt directly to the tranny that was attached to the 273 after I do a rebuild. I was already thinking of frame rail connectors and replacing front suspension parts with Hotchkiss kit.

I think this engine may be a good purchase to add to it. the 426 sounds like more work than value for what I want to do. Thoughts?
