Default World's First Flex Fuel '70 Chevelle!!

Well, that I know of anyways!!! We are working with a customer on his '70 Chevelle. I guess going through 3 sets of tires last year with the 6.0L wasn't enough, so this year we have built him a 415 L92 Corn burning Monster. This engine made 575HP and 600 ft-lbs on the engine dyno. We are in the proccess of making it a full flex fuel vehicle, but the 4l60 finally said enough is enough. So, now we are going to go with a full manual valve body to hopefully get this thing to live.

We will be at Car Craft with this car and hopefully a '61 4.8L/T56 Corvette also with flex fuel capabilities.

Hope you enjoy the pics of the Chevelle!!!!

Can you explain the coolant reservoir on the head? Looks like you're running the steam vent into it.

It's actually a surge tank. We use them to get all the air out of the system by being the highest point in the system.

Very, very nice. Good job....not my style of car but I can appreciate a job well done. You beat me to the punch (because I'm sooooo slow). I still may have the first "Flex-fuel" old school hot rod though. Of course out here they don't hardly sell any corn-fuel anyway.

What year ECM did you use? I go to Car Craft every year, where do you guys normally set up?

BTW - Do you make the valve covers in black?

Last year we were set up on the North end by the FAST/Comp trailer.

We don't have the covers in black, but we could get them painted I suppose.

I am using a 99 OS for the controller.

No big deal, I can paint them. Can you sell them unfinished (not chromed)?

I think they all come that way. I could see if we can get some made with bare alumin, or I guess we could just blast them so you could paint them.

what ECU are you using?? im guessing you need an aftermarket one as the stock one dosen't have switchable maps dose it??

the you customer to bolt some turbos on there. then he can have an octane on demand system!!

Chris.

PS are you running 2 sets of injectors and a seperate fuel system or a single one??

Chris,
We are running a stock ECM with a '99 operating system. We have some secrets about making it work. We are using the Lucas 42lb/hr injectors running at 58psi with only one fuel system. I think he has all of the power he can use for right now. I think this will be the end for this car. Maybe his 50 something wagon will get more go.
