That is a sharp engine. Some of those parts don't look like off the counter items.
I am running 2 600's on my 392 Hemi, and I wish I had gone with 500's. I think I will try the blocking off the secondaries as suggested. I only wanted the 2-4's for 'looks' as someone else already said. I don't do burnout contest and I don't race it. I do dirve it often and lotta miles. I drive it on vacation often.
