Planning first engine build, need help

Msd Part no:32749. Super conductor wires. my bad i remembered the wrong name. I had to cut and fit them, engine ran fine and i had no issues with missfires after installation but i still have the original plug wires if you think thats the issue.

No I'm sire the wires are fine. They make good wires. What plugs are you using? Where is your initial timing set?
