I'm doing an LS3 swap into a 78 Camaro. Some time in the future I would like to do a high compression naturally aspirated set up for this. So I thought now might be a good time to set it up for E-85.
I haven't bought my fuel controller yet, was planning to use the Holley TermX Max.
Also any thoughts on stuff I should get to do this? Any one here have experience doing this? Wondering what size fuel line and injectors etc I should be looking at?

 

As you already know, you'll need about 20-25% more fuel by volume. Upsize the fuel pump and fuel lines to match that. You don't have to do anything radical, just make sure everything can handle the volume.

 

Ok so the Holley Sniper retro fit tank and pump system I was looking at says max fitting size at the tank sending unit is 6AN.
That's probably not large enough is it?

 

I found a chart for E-85 fuel line size and it says for 800 hp recommended is 8AN with a 6AN return. I'm planning a 720 hp NA build eventually.
Maybe only way to do this is using a fuel cell? Not opposed to going that route but would rather keep it looking stock as possible. That's why I was looking at the retro fit tank.
Any ideas?

 

You would probably be better off getting a new stock tank and put a sump in it or go with a fuel cell over the Holley retro tank.
Have you tried Tanks Inc ?

 

I have.
Honestly I've not heard good things about them. Problems with cavitation. Quality control? Heard enough that I thought I should not go that way.

I'm getting conflicting info on the subject of what type of tank is acceptable for storing Alcohol.
My friend did E-85 on a blown big block and he is just using a standard metal galvanized tank. He says no issues, but then he has only been running it for one season. Others I've spoken to say this is a no no.
Is stainless a better option?
Theres a company called "Ricks" that lists custom stainless tanks but they aren't cheap.

 

I've been running alcohol for years in a stock tank, with a stock replacement pump, and stock nylon lines. No problems at all. E-85 is not corrosive like methanol is.

Instead of adding a sump, consider using a Holley Hydromat. I have one in my race car, and it really works well.
