Mike, yes brought the Duster here in Jan. I am building a new car while I am here, 71 Demon, R5P7, Liberty Extreme 4spd, 9", 4 link, struts in front and a Bruno. should be a fun car. It will be a Nostalgia Pro Stock. But I am going to get a second hood for it and I think a different rear spoiler so it will look modern if I want too. Also a second set of rims. I think this is the most detail I have given on the new project. What size air bleeds do you have in the Dominator?

Charger, already did that. I pulled the plugs when hot and bumped the motor and heard it splash on the floor. Rolled the motor and got it all out. Waited over night then put the plugs in. It is running fine now or is it seems to be. I roll the motor until I get pressure before I start it. I was worried about that too. Just need to change the oil. Going to take it for a quick trip around the block, make sure it is not loading the cylinders with fuel and then change the oil. Don't want to waste the brad penn oil...

I will post tonight what happens, or tonight for me on the west coast.

If you had fuel pumping out of the cyls. that bad, I`d be more worried about the fuel that went past the rings and killing ring seal and diluting the oil and hurting the motor than the Brad Penn oil.............Which is cheaper a re-build or 6-7 quarts of oil.

for sure! Compression check ( comparing to previous checks ) might be in order after you get your carb issue squared away. Fuel washing cylinder walls can be a BAD thing.

All very true. I think I will change oil. I do use a fuel lube with the E-85 so maybe that helped a bit.

Smart idea and agree about a cranking comp. test to see how it`s sealing. Do u have cranking #`s to compare to? If not no biggie just post em so can see what ya got...........

Changed the oil. Oil was a little milky, got about an extra half quart so some fuel passed. No compression numbers to compare to. Dont have tester here with me either... It easily pushed my thumb off when I rolled it over and no more came out. Also squirted some oil in the cyl before starting, rolled it over until I had movement on the gage. Fired right up. A little grumpy when it was cold but once warm idled with no issues. 70psi oil pressure. took about 5 min to hit 140 with the pump going.

I will take it around the block tonight, pull the plugs and see if any fuel comes out. But when cracking the throttle it is not pouring fuel like it did before the changes.

So I have my fingers crossed nothing was/is messed up. i am hoping I dodged a bullet by using heavier oil 50w and the fuel lube. If not, well I cross that bridge then.

If I missed something let me know, any thing else that can be checked point it out.

Thanks for the help and tips.

Pulling the plugs will tell you what`s up but if you can borrow or buy(ther`re cheap)a cranking comp. gauge and see where it`s at that would help OR a leak down tester.............good luck.

Plugs were good when pulled, clean... I will check them after the run around the block.

I will see if Harbor freight has one. Good call on that I will need it in the future.

Good luck................ I personally crank mine cold just cos it`s less painfull/easier and hook it up to a batt. charger w/carb wide open...............

I get the less painful. Used to do leak downs on a 700+ N2O motor after a pass.

I am on it.

Thanks!!

I would bet that the float is set just a bit too high. E85 has a different weight than gas so you can't set the float as high as gas or it will pull though the boosters. Same with fuel pressure > can't run as much as gas or it will blow past the seat.

I've been racing on e85 for probably 5 years now and the learning curve was significant.

Check out Vernmotor's post about his e85 adventures with his 950 hp. He had a good baseline for jets and air bleeds. LINK

if you change the power valve lately you mite have got the gasket out of line or lose,it would put gas in the motor,I did that loaded the motor with gas.

I am thinking that is what happened. When I bought the carb I did not check it. My fault. I found the PV gasket was off, there was no crush on a portion of it.

Jetted down to 93 squared, I think that is a touch lean. Going to go to 95's and let it fly. The motor got a little warm a little to quickly for my liking but could be my sometimers kicking in and me forgetting that is normal....

I am going to get a 50/50 linkage for the secondaries too. But that can wait.

A few other things to take care of on the car and will be ready for the street, I think.

No compression tester to be had I will check the local part houses and see if they rent them.

Not too worried about it. Took it for a test run lastnight and it was peppier than I remember. Just rolling it up to 5k rpm, the converter flashes at 4700, it started to slide around at. So I am thinking she is now good to go.
