Apologies for the hijack here but what studs are you using on the water pump to block? I've had a gasket go behind the motor plate at the track before, this set up would make it a bit easier. TIA

Awesome Andy. Would like to see some more pics of your car. Just an old Coronet. It was a street racer back in the 80's and then I was going to drag race it in the 90's but I never really got serious about it. Now I'm slowly piecing it back together and trying to fix it up a little. It is a little too loud and uncomfortable to be a daily driver. I think the EFI will tone it down a little but I might need to change the cam or do something else. I'll probably down size the exhaust from 3 inch to 2.5 inch over the winter to see if that makes it better.

put me down for one of the thermostat housing adapters as well!
The one I got has the sensor sticking too far into the thermostat well, interfering with my hi-flow t-stat...

Just curious why you stuck with the throttle body type system here and didn't go with sequential/multi port like we've seen on your other projects? Keeping it simple or...?
Are TB systems getting more precise?

Are TB systems getting more precise? That is an interesting question, I had to think for awhile on the answer. I guess it boils down to wanting to have actual hands on experience with as many different flavors of EFI as possible. I'm trying to develop some expertise on the subject and the only way to do that is to actually get my hands dirty with multiple installs and to tune different engines with different systems. I think the Super Sniper is good enough for what I want to do with the Coronet but we'll see. I won't know unless I try.

The FITech has 1:1 linkage also... It took a little getting used to pulling away from a light without the car jumping on the converter.
I did notice my lean limit before I run into surge is leaner than the carb, and I attributed that to more uniform air and fuel distribution between the cylinders. But I haven't verified that with 8 WRO2s, haha.

I'm going to switch over to a progressive linkage. I think the 1:1 is unsafe on the street with a big engine. I did some data logging and at 4000 rpm I'm only at 25% throttle opening. 4000 rpm with a 512 inch engine is starting to make some noise and is really moving the car along so it is crazy that it is only 25% throttle opening. That means my street driving is confined to just a tiny bit of throttle travel. The 1:1 might work okay at the track but it is way too sensitive in my car for street driving. Is the software compatible with a progressive throttle? You need to be able to tell it at what throttle position value the secondary blades come into play so it can fire the rear injectors and also to shut them off below that throttle position. Kevin
