This thread is dedicated to crossfire owners that have ported their crossfires with poor results. I ported my crossfire and it didn't do much for performance. What is needed to make these ported crossfires run fight. Higher stall convertor, a special tune, roller rockers?

Excellent point. However, at least when this thread gets locked, no one will care.

Unfortunately, The OP has a nasty habit of ruining, then getting locked, others' threads that actually DO have merit. Here and elsewhere. A shame.

Fixed it for you.

BTW, haven't you already had this very same question answered for you, on several other forums? Try searching under your plethora of user names and I'm SURE...that you'll find this exact question, asked by you, and answered.

Nice job locking up Kangi's thread, BTW.

Good luck finding CFI porting nay sayers.

Instead of opening up a cfi manifold, open a trash can and dump it in. Fastest way to gain power

I have a better idea. How about to open the lid and dump a dump in it?
