Has anyone completed an LS conversion in an older truck (80s) and went all the way with the Flex Fuel requirements? Besides the engine, what on the truck/gas tanks has to be changed to run E85? If so, did you do a build thread or have the parts list required?
What's the advantage of running e 85?
I was totally surprised, but I have seen dyno charts actually showing an increase in both HP and torque using e85 over regular gas. I'll try to locate those charts again and post them here.
Wow crazy! Guess it's all about how it's tuned and supporting mods?! After Nelson tuned my 08 flex fuel for cam and stall and stuff they said not to run e85! I'd like to read up on it also! And If you havnt started the ls swap its simple! Just finished mine up bout a month ago!
OK, I admit that this came from a GM website.... but this is why I am looking into making the whole truck E85 compatible. I am installing a LC9 in my 82.

I would have to think that all the rubber lines/O-rings would have to be changed in order to be compatible with E-85. I would definitely do some homework on the subject before tackling that task. Good luck and let us know how you make out.

If your not going forced induction I wouldn't even consider e85.
99 rcsb silverado...... boosted.
You will have to redo all your fuel lines to be compatiable with E85 and the correct fuel pump.E85 does make more horsepower but you will also get worse gas mileage.
