What to do? Help me pick...

Tuff call. I think the 408 is my style. But that new HEMI and back it up with a modern tranny. WHEWW! Hard to beat that combo. And if you are beat, theres nothing a little cam, head porting and a blower won't solve!

I remember some mag did that with headers and pounded out over 700 ponys.
Sceeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeam!!!!!!!!!!!!!
