Lets see how everyone has handled their plug wires. Routing, looms, etc. I want to use 90 degree boots on the distributor ends, and route the wires more behind the heads to clean things up. To me, the straight terminals on the distributor looks like a spaghetti monster. I have custom Mopar Performance valve covers and I am in the assembly/clean up process now. Discuss.

Your choice. Route them for looks or route them for performance. There's no power to be gained, just problems to be avoided.
 
Passenger side easy, drivers side is a little more challenging to get neat. Also drivers side makes a difference if you manifolds or headers.

Straight boots don't have to be a mess...

I think the key is the 2 wire loom for the front wires in about the location of the original factory valve cover looms and then a 4 wire loom at the back to set that up:

Nice example. The 'floating' wire seperators help too.
Factory examples shown here.

273 V8 spark wire routing, looms and grommets

I am hoping someone has a picture of how the spark plug wire were separated and routed from the factory and where to locate those pieces. I have searched over the web. Lots of stuff for big blocks… i have the valve covers with the spot welded tabs. Thank you.

I don't see that square one very often.

Engine compartment pics

Maybe I just couldn't turn it up in a search, but has there ever been a thread here for engine compartment pics? People have good ideas for air cleaners, catch cans, spark plug and heater hose routing, etc, and it would be good to have them all in one place. Mine isn't complete yet, but here's...

I don't know what exhaust system you have, but anything that is even vaguely shaped like a drivers side 68-70 340 manifold those would not work with - wires need to stay higher then drop right down to the plugs. I have seen various header routings that stay above the head ports that would have the same issue.
