I've been looking into this idea recently, anyone running it on a carburetor engine? It looks pretty basic, upgrade to an aluminum fuel cell, larger fuel lines w/ air water separator after tank and before pump. Run like a Holley black pump and throw bigger jets in the carb.

I was reading up on raceone85.com

I've got a motor I'm putting together over the winter and was thinking, instead of trying to keep the compression low enough to run on pump gas to just go e85 and push it up around 14:1 compression. Would be cheaper and gain lots more power correct?

You can barely break 12:1 with a std bore if you used domes, a .015 hg with a .025 deck and 50cc heads. Stroke and bore should get you more. Some early 80s 601s or some shaved lt1 heads converted to std cooling.

quick fuel makes carbs that are already set up close for e85 and have all the updates needed for the corrosiveness that comes with the e85, would make lots of power on a high compression motor

I was thinking of a sbc 400 zero decked with domed pistons 3.75 stroke 6.0 rods. Haven't decided on heads yet.

Uh that is the stock stroke mang. Your odds of getting to that comp ratio are way better with a 400 though.

The 5.56 rod is stock. Keeping stock.stroke 3.75 going 6.0 rod with domed pistons and 58cc heads maybe even 64cc ish. Zero decked. Its possible to go to 14.1 ish c.i.

Question was running e85 should save some cash in the mpg area right? And gain some HP while at it right? is it worth it? Cleaner oil? Less heat in the motor?

its cheaper than running race gas, but with the lack of mpg it will be about the same cost of runing 93, it would be worth it if you plan to run 14:1 comp since you will have to run 110 if you dont run e85, or if you have forced induction its worth it

I'm just about at the starting and tuning stage with the bel air on E85. I got in contact with C&S for a blow thru 950 holley set up for E85, so far no complaints. Technically you should be changing out fuel lines that aren't teflon coated but we've ran quite a few cars on SS braided rubber lines without issue even on E98.

The rubber ss braided lines go bad after awhile. Seen it a number of times.

The evo II was put together in 06-07 with rubber lines still dynoing 1000+ awhp on E98.. I'm not saying the lines going bad doesn't happen but I know quite a few people that haven't switched to PTFE. :dunno:
