360 questions

The 360 is a fine engine for any car. It was built for performance, but performance you can use..That's low speed torque. I would do a solid performance rebuild on the shortblock. KB (or similar) pistons at 0 deck, re-done factory rods w/ARP bolts, blueprint the block, and internally balance it. Wiht the right top end and cam, you have a base that can make 275-450hp reliably, on pump gas. For heads, a good set of performance iron heads will cost around $900 to get done, and done right. That's mild porting/gasket matching, new SS valves, chambers cc'd, the works. A real compression of 9.5:1 with factory heads, the right cam, and you have a solid 425tq and 400hp on tap..Reliably, that will last daily driving for years, and run on mid grade pump gas. With an upgrade later to Edelbrocks, or similar AL heads, you can get more compression, more power, on super unleaded. That's what I'd do. Around here, it would cost $3K or so for a long block, a little more with the oil pan for the 360 (not the same as 318)

On the mount thing..Chances are, the catalog is wrong DC..not your fault. Contact Schumacher Creative services for unbreakable correct mounts for a 360/340 in a later Dart. The earlier biscuit versions are easy to get off Ebag, or several suppliers for $20-40. You may be able to get the right mount, by having a good parts guy (not the typical P/C typer at Auto Zone) look in a book (real printed ones even..) and get the part for a '73 340 Dart. I'm not positive, but many passenger cars with 360s will probably use the same mount, like a 360 Monaco, diplomat, Fury, Barracuda/Challenger, etc. for '73 to the 80s.
