Hey guys

I want to switch my 370 to E85, since i can no longer get 93 octane around here and have heard some knock under power because of **** gas. I can only get 91 and don't want to go through the motions of mixing race gas in a street car.

Right now its a N/A 370" with PRC As Cast LS3 heads, 11.2:1 compression, Pat G Cam, 230/234, stock LS3 injectors in an 85 Corvette. I have an in-tank 255 pump. I think the pump should be large enough? My system is a return style at 58psi.

I think 80 Lbers should be enough...any preferred brand? Siemens Deka?

 

DEKA 80's is what I'm going with on the 99 Camaro and just make sure you have enough fuel pump.

In Pat G We Trust!

 

I think I'm gonna go to a 340. Apparently my pump might not live very long with e85 lol.

Is there a good vendor for the Siemens? Forum sponsored one?

 

340 should be enough pump for 900hp and I purchased some through Tick Performance but they drop ship from Fuel Injector Connection. Bad part about E85 is uses three times the fuel so if a street car you'll be stopping often.

 

It is a street car, I just daily drive it locally. Pipe dream right now is to run a flex fuel sensor with a turbo setup so when I want to drive like a dipshit I can put corn in it and when I want to go for a trip I can put pump gas in it and have the tune adjust accordingly automatically.

Oh well lol can't risk destroying this engine so frequent fill ups it is
