This is a clip from this evening after work of the 408 w/ 233/239 .595/.603 113LSA running through dual 2.5" exhaust and flows. Right now it still has the manifold on it until the headers come in. Idles nice at @ 800 rpm. Enjoy!

man, that thing has a nasty miss to it.... might wanna check your air filter or plug wires. haha, any numbers yet? sounds wicked man, good job.

 

Sounds pretty good to me but it'll sound better when ever you get those manifolds outta there. Great work!

 

Thanks guys, the Pacesetters are on order, was really wanting 1 7/8" but didn't have much luck finding any as affordable as these. Also gonna chop the exhaust right behind the mufflers and turn them down with 3" turndowns. No numbers yet, waiting on the longtubes and a little dyno tune and it'll be set.

 

Sounds good man, I thought that video was going to optimize forever!

 

Sound real good at about 6800 rpms!
