 :wave:

Car has been running good, I had some spark plug wire routing issues in the beginning, but those are fixed now.  My cheap MAF from rockauto stopped working so I am running in speed density right now, definitely a little rich.  Hopefully in the coming months I can purchase the stuff to do my own tuning.  Still needs some small things, and once I start doing some drifting events I will dig more into suspension set up.

Thanks for bringing this up. Although I am installing a 5.3 L33 some of the pictures help out a lot.

No problem, if you need any pictures let me know, the engine will be out of the car for a while.

Can you take a few pictures of the brace that you moved forward for radiator clearance. Thanks!

No problem, the radiator mount itself is a granny's piece but I am sure you could fab something similar.  I want to say that is 1" or 1.25" tubing, .065" wall I think with 1/8" steel plates on the ends.  I can try and dig up the template for the end plates but I am not sure if I have it or not

I have a nice set of header for you, they were used in my FC but they'll probably fit your FB?

They're Headman shorties that had the flanges replaced by 1/2 think LT1 D-port pieces and ceramic coated.

That won't work... didn't think about the steering box.

The drivers side outlet is right where the box is  :(
