Re: LeRoar still having issues

["Steve Mick" <micher@xxxxxxxxxxxxxxx>]

Rich, I am still thinking it is in the intake.  When I test fit my new alum intake  on heads that had beeb milled slightly. I set it on the heads with no gaskets. I then used a feeler guage above and below the corner ports to see if the angles were the same. There was such a slight variation that I knew the intake gasket would seal all around the ports.  Hope that is a clue as to what is going on............................MO

The item on the fenderwell is the pressure regulator and gauge.  I really don't need the regulator with the new pump so I will be removing it soon. The pump is inside of the right rear wheel.

Yes the wet side is the cool side. The left bank. 

This happened after I had just installed the old original 2 bbl stock manifold. I tried the original carb and it was way to lean.  I messed with the jets and got it running quite good with vac numbers up in the 20-24" range. Then after 20 miles or so it started running crappy again and the vac dropped down to about 17" quickly.  I tried a Holley 2bbl.. No good.  Then I got my 4 bbl Weiand 7503 back which I had previously used successfully for a short while. It still ran crappy with about 14-15" vac.. I torqued the manifold down in a circular manner like the heads.  The car runs very cool even when idling for extended periods.

The switch to the 2 bbl stock dual plane manifold was done when changing to the new 244deg hyd cam.. I also switched the trans and converter back to stockish and the heads were the ones I had used since my first build until I got the "trick" heads from Gary P. 

The alternator went bad so I replaced it and the voltage regulator. The voltage is good now.  I replaced the ECU and swapped the ballast resistor. (It's a .8 ohm which was my original)  I do need to adjust the timing I believe as I didn't disturb the dist so I hadn't changed it since the 4 bbl was installed. It was set for the 2 bbl's though.

Maybe the coil is weak but it doesn't make sense that only one bank seems to not be firing well????????  I will check the spark intensity soon.

Yes, a rich fuel mixture will be cooler, but will also be inclined to wet the plugs.  A lean fuel mixture will be hotter and leave no unburned fuel to wet the other plugs.  Or so I think...........................MO

                The wet side is the cooler bank of cylinders?

This left and right difference is the puzzler. Did it pop up after you changed the intake? (For that matter, exactly what did change between the time you had a good set-up and it went sour - narrow it down?) If so, do you tighten one side of the intake first and then the other? I wonder if the manifold is too narrow and the side tightened last is not snug to the gasket? Maybe you could loosen the intake bolts and do then in reverse? If that shows a change, use the paper gaskets with the sheet metal pan and try again.

 

Anyone have an idea on how to measure the width of the intake and distance between the heads for proper fit?

Rich, those symptoms have me baffled.  The only thought I have about it is -could the single plane intake be the problem? What conditions could make it draw more fuel toward the cooler bank of cylinders, or less fuel toward the hottewr side of cylinders? Cooler cylinders with more fuel going to them would show wetter plugs and visa versa.  ....??????.....MO

Eddy's can't handle more than about 6psi or the floats get bent out of shape.  Been there, done that.  

 

The pump is a new Mallory unit that is designed for street application without a regulator.  I may have to swap the pump back to previous to see if the problem goes away. 

 

The new cam is the 244deg hyd grind.  I don't remember if I degreed it this time. Prior to the alternator issue it was running great with almost 24" vac and smooth as silk with the new cam.  The new trans was giving me fits and I spent a long time under the dash getting the PB's to work right. Sometime after that is when it went wacky. So I did suspect I damaged something under the dash but after spending some major time there I couldn't find anything wrong.  The alternator and volt regulator were replaced and the voltage is stable now.

 

I switched out the ballast resistor and  changed the ECU.  All to no avail.  The plugwires are 8mm Taylor's.  I was wondering if the dist pick-up needed to be checked to see if it shifted.  It has to be set with a brass feeler gauge. I will check it out.  I have at one point or another sealed all vac ports incl the vac advance.  No change.  I did not re-adjust the timing yet and I will get after that asap.  The manifold has been changed from the 2bbl to the 4 bbl and I have tried 3 different carbs. The current Weiand manifold is a single plane.  I intend to check spark intensity soon also to see if the left bank has a lower voltage.  I don't have a spare coil but doubt it's my issue.  The left vs right bank issue is what really stumps me!

 

Thanks for the input!  Keep it coming.  I won't probably be able to work on the car again until the week-end.

I don't know the background prior to the alternator issue but did you degree that new cam?

Also, like Don said that fuel pump pressure seems low.  I would desire 6.5 - 7 psi.  What setup is that in the inner fender, anyways?
