Larger Primary Race Headers?

mr.squatch · Feb 25, 2004

I'd like to get a larger tube race header but am finding nothing but resistance. The big one fc uses is "not in production" and "cost prohibitive to build just one" etc. I know the kamikaze is 2.5 at the back, are the primaries any bigger? I have an old fs catalog that states theirs is too. Curious does ANYONE make a big tube header?

The SVT header for ZX3 application that Ford Racing is selling has larger primaries than the FC one.

Odered mine yesterday from local Ford Dealer (price hookup, thanks COSitsWORTHit) found out today it's backordered till the end of March. It's worth the wait though, for the price and gains.

The kamakazi does have bigger primaries then the other race headers offered.

I believe the FS 4-2-1 has 1 5/8" primaries.

14.405 @97.58mph

With a 1/4 time like that, hes probably got something done that needs a lot of breathing.

haha, that was the old motor with a little nitrous... the new motor will see 12's... thus... need to exhale.
