How are you planning to mount your 3 link?  I'm curious about the body mount side since you said you want to do an offset non interior mounted setup.

I ran mine centered and through the floor.  It was a pretty simple install and fits under the storage bins.

I ran mine centered and through the floor.  It was a pretty simple install and fits under the storage bins.

I am going to the pull-a-part with a battery powered sawzal and cutting out the rear tunnel under the bins of a wrecked FB.  I will cut the top off and the right side of mine, and, well do a little plastic surgery.  I can weld sheet metal pretty darn well... So basically I am making the tunnel taller and wider to the right.. (I only have to make wider to the right by about 1.5")

It will be a little while before I tear into the rear end...I have to finish my fuel rails, Run 3/8" hard line from the fuel pump (that still has to mounted yet), pull the tank and weld in a sump to it,  put the motor back in, wire up the EFI, mount the FPR plumb it, mount the MSD/Coil, figure out throttle cable, speedo cable, mount the radiator, clean up the wiring under the dash... on an so on.,..   
I have a white dry erase board in the garage, I listed everything that needs to be done front to back. As I finish a task I mark it off..  Rear end is toward the back..

Are you using a panhard bar or the stock whatts link???  with your three link??

I see.  The factory tunnel seems like the only hurdle to keeping the bar outside of the body and asymmetric.  The widened tunnel would be interesting to see when you finish it.

I've got a panhard bar with the 3 link.

Well I was slowed down by the holidays,  but I did manage to get out in the garage and sneak in some work..
Like Fuel rails









I even found a few hours to assemble my MSII EFI.. 
I have to make the stands to attach the fuel rails to the intake manifold.  Also  plumb the front of the rails to each other under the plenum  with -6 aluminum hard line..
Sorry but I did not get any pics of making the fuel rails,  It was cave man done like in a drill press with a dial indicator attached with various clamps..  17/32 and a 13/32 bits a counter sink and lots of polishing by hand of the injector pockets in the rails..

Worked out some details of the intake fuel rail mounting..



Getting the dimensions for the spacers




Cross over pipe, had to clear the thermostat housing


Cross over pipe, cleaned up, trimmed the mounting  bars and radius the ends


Mount cleaned up,


Shot of the rear, I put nipple in the 1/2" spacer for the FPR and the MAP sensor..

You can also see in this shot the 3/8" NPT holes in the #6 runner and into the plenum..    I was thinking of using the center one for PCV and the one the runner for vacuum brake booster..  opinions welcomed if there is a better way..

Another shot of the cross over pipe

Getting ready to put it in..


Close up of the clutch fork.


Clutch slave (CNC from speedway motors) finish the mounts and cleaned up.


I decided to paint the engine block semi-gloss black.  The chevy orange was just imo "gay"  the final paint on the car will be black.


Cross member bolted in


Pulled out the fuel, return and vent lines since I will be running new -6 hard line


I can't remember were I got the starter, but is is a mini, permanent magnet, planetary gear reduction with a stock type mount..


-6 hard line for the PCV,  -6 90* fitting for the brake booster, billet dizzy and oil pressure sender.


The plan is to get it in, wired, plumed, drive line done and get it started.. Then it is all being pulled out. The shell will be placed on a 1x1 frame with 10" castors and the body/paint mayhem will begin.
