I have a 400 stroked to 505 in my Challenger. TF 240 heads and TTI headers.
I have a 2 inch scoop on my hood and I have a victor intake so that won't help you any.
If you go with the TF heads just make sure you get the right rocker setup.
I have the Harland Sharp set for Mopar heads but they are too long and don't hit the valve stem right. I have the HS set coming that are made for the TF heads.
