Summit Plug Wires - Long Enough for BB???

I need to make set of plug wires for a stock 400 for my 66 Dart. I'm trying to go cheap now because I'll likely have to make a different set once I put the 470 in it w/ angled plug heads and custom headers.

Have any of you guys used these Summit plug wires on a big block? Summit Racing SUM-860825R Summit Racing™ 8mm Ignition Wires | Summit Racing

I'm wondering if they're long enough to reach cyl #5 and #7 and others. I called Summit and they do not have the lengths of the wires. Thanks guys. I appreciate it.
