You have to chop the crossmember.

No, not with the engine in stock location, look at the 2 center ports and visualize, it won't some close.

The only way is to shorten the crossmember(illegal sometimes)or cut a hole for them to go thru,but be ready for some broken manifolds when u hit something.The only other way besides rewelding them is to use the angled back style,and even then i'm not sure they will clear.

my buddy has the type that angle back and they will fit with no mods but the straight ones like you guys said won't work

if you run the ones that both angle back you will be fine. The only problem is it is very hard to find a right side one. and also its really tight getting the exhaust bent around the starter but its worth the hassle.

but aren't the ones that angle back the small outlet ones? Are they that much better than the standard car/truck manifolds? Thanks.

i went from runnig headers to running manifolds due to a rule change. Using the angled center dumps with 2in exhaust runnig back to the passengers side i didnt notice that much of a difference in power loss. i do know that a lot of people around here in ohio like using the "log" style manifold found on the newer vortec motors out of a truck. they are rear dumps and are exposed to be as good as rams horns.

You'll have to cut the crossmember to get the 2 1/2" ram horns to work. The "backswept" center dumps will work fine tho. After modifying a set to the swept back style (hogging out and lightening) I read Brezinski's webspage concerning the manifolds. He says that the 2 1/2" are the best... followed by his log style. He doesn't have anything to say about the vortec manifold. I surmised that, if the vortec were the second choice, he would have offered a set of them (modified by his shop).
I suspect the track I race will have a rule change for 2004, allowing us to use headers. If that happens, I would be happy to sell both sets of manifolds-the Brezinskis and the "swept" Rams horns that I worked myself.

I just looked at a new style manifold. Nice 2,1/4 outlet but the #2 port is real restricted and I dont think theres enough there to open up

A little massaging required!

Hmmm...what if you flipped them upside down? Just a crazy thought.

Dode,

Not so crazy, at old riverside a figure 8 driver used to run his that way and out the top of his hood.

Now what would JD say, thats the real question isn't it?
