new headers -> old headers

New headers from summit!  I feel like such a redneck whenever I get psyched about things coming from Summit.  Option 3 the block huggers:


Shortest lived excitement ever:
Yep there is a reason why all the links and threads about block huggers link to hotrods...

I assumed it was because hotrods have narrow frame rails.  Turns out...

There is no way they will work with rack and pinion steering.  Well almost no way.  Maybe if I buy a front sump pan, and go back to rear steer. So we will say no reasonable way.  I read in a book that worm and sector steering will feel identical to rack and pinion if it is stiff enough.  Which is like saying a port-o-john would make a good home if it was just bigger, not plastic, had furniture, and smelled a little nicer.

Those of you keeping score know that I have three non ideal options:

1) Original Shorties
+ Free
- DS collector is in the way of the subframe

2) Tri-Y
+ Look cool
+ DS fits with no modificatin
- Limits how high the engine can mount
- PS collides with the subframe

3)  Block Huggers
+ nowhere near the subframes
+ great flexibility for routing after the header
- Hits the rack
- Hits the starter
- Hits the engine mount
-BTW you get what you pay for.  Mounting flange is about .060inch out of flat.

Looks like it will be shorties.  Today I loaded the DS one back on.  Now that the engine is an inch higher, it barely interferes.  Since I would like to go up another inch for bump steer, They may clear with no modifications to anything.  Difference now is that back when I started this saga, I was not planning on chopping the tranny tunnel.  We will see if it is as fun to send things back to summit as to get things from them.
