so you have the trans dapt mounts too??

negative.  You don't need them, I tried to tell him this, but.... whatever.  I only got the headers.
His kit moves the motor around and I wanted mine back as far as possible so I got Edelbrock 1" back plates, same ones everyone else sells.

Looking good.  Your header clearance is perfect.  At first I cut up a bunch of stuff in my truck to fit my headers, but then I changed to different adapters that lifted the motor and moved it back an inch...that made all the difference and would've saved me from cutting.  Do you have the cooling system all figured out?

The Diesel radiator if ok is better for high heat as that is the big killer for a diesel.

I am using the EFI tanks, but S&P don't on all of theirs.
The 241 put is what you want also.
I bought TBI lines for mine and used them on my truck.  You could also use braided line all the way.  If you use a 99-up corvette filter it has an internal regulator and you only have to run a supply line to the front.

I got my hardlines from Inline Tube or Classic Tube.  I go the braided lines from Pure Choice.
