Very nice!!!
Is your LC-1 tapped into the #1 exhaust port?
Or is that an EGT sensor, hard to tell.

I am sure you will be burning rubber in no time!
What is the stall on your torque converter?
I'm always a big fan of the 2004R's ,nice gear spacing!!
I see your boost referenced Holly FPR, nice!

The only problem I might see coming will be the passenger sytle engine mounts.(Tall, thick, spongy)
They are going to flex like crazy!!! Engine is going to torque right over!!
You could install some sort of engine tie down.
Or install V-8 mounts like Tom did on his 65 ElCamino. Two cents :-)
For the rest of your exhaust system,what are you planning to run?
3" all the way to the back, straight through muffler?
