I think the system is capable of sequential, though as I recall Edelbrock doesn't make a dual sync dizzy. The Pro-Flo states that it can do sequential, just need a cam signal. You can run batch, but it's pointless to do multipoint if you're not doing sequential.

The Edelbrock ECUs are nice.

1969 thermostat housing and upper hose arrived today - seem to fit much better but will require trimming and twisting.

I can make a reluctor wheel to mount to the balancer - it would sandwich between the balancer and pulley. The sensor would mount where the fuel pump was.

I have not seen any reference to Eddy's setup allowing for cam sensing.

PRO-FLO 4® EFI SYSTEMS

"Pro-Flo 4 offers the ultimate in performance and power with the precise efficiency only a full sequential port EFI system can deliver. Full sequential port EFI systems delivers fuel into the intake air flow right at the port with an injector for each cylinder, allowing for better fuel atomization & distribution."

So that made me wonder, and I looked at the wiring diagram. Looks like the CAM signal is pulled from the crank signal, must have some type of compensation in the software to calculate for an actual cam sensor signal. Interesting.

"the Pro-Flo 4 system also comes with a Hall Effect pickup distributor that outputs a unique position signal that is both a cam and crank sensor to make the sequential system operational."

Interesting.

Excellent - thanks for sussing that out. The Tuned Port's were batch fire and did not suffer too much - this should be that much better.

I know the Edelbrock stuff is quality, aside from maybe a couple minor features, they are up there with the best retro kits for the money. I've never heard anyone complain about them.

I hope so, will find out in a month or so...

Working on suspension stuff. Being in my nature to not leave well enough alone - I tried another approach on the rear sway bar. 2 basic styles are offered: the OEM bolt to the control arm which supposedly cause binding and the conventional style. The Trans Am style won't work due to space constraints.

A few months ago I help swap out the stock V8 front bar from a 68 Firebird and got the old one - it is 11/16" Ø. I shortened it to 32 inches overall, cutting off the "arms". When the frame was sandblasted I welded on a pair of ears to the rear cross member in case I decided to follow this thru.

I plasmaed a pair of arms from some 3/8" stock (next time will simply by bar stock!) and machined them to match.



Two holes, one 11/16" for the bar and the other 3/8" were drilled/machined in. Arms were tacked into place then full boogey with the Heliarc.



I hope it holds and does not break. Years ago I did something similar with my 66 442 as the bar I wanted to run was too wide - I simply cut a chunk out of a TA front bar, used some tubing and welded it back up - ten years no breakage. Something to be said for being an apprentice tinner and not knowing it won't work...

Front bars got some love too - the rear passenger hole stripped out before I started this. I bought some nutserts and a tool to install them. Nutserts are like pop-rivets but form inner threads. I had to drill and taper ream a 0.530 hole for this to work - not exactly something laying about. The tool could use some refinement ie. a washer welded in for overhead work.

Another reason for the rear bar work - according to my calculations, the 11/16" bar with it's shorter arms and overall length will have 71K lbs/in versus the 34K for the stock bar - if the whole rear arm in used for moment length.

By the same calc method the WW5 Y99 1"Ø bar yields 59K.

Front hubs getting a checkout - 0.002" runout: acceptable.



The dash arrived from Just Dashes. Very good work but quite expensive and other fees left a sour taste though.



Testing the radio, a 70's vintage Audiovox designed for 78 and later GM's. Could not give it away - but it will replace the vintage late 80's Alpine unit. Sound is fair enough but I love the look.



The OEM oil pressure gauge was always pegged - at 80 psi the resistance was almost 115 ohms vs. the 90 it is supposed to be. I have 2 other senders that are somewhat better but may need to use a resister in parallel to knock it down some.
Resistance was checked with an air compressor and chuck with 1/8 NPT tapped into it.

Mind if I ask what you paid for the dash?

$1,100 for the work, 128 shipping and a 3% credit card fee.

Whew. Well. It's kind of right in there. The range I found was 900-1500.

Curious how the glove door and gauge insert fit, those are usually the areas that suffer from fitment, might want to mock it up.

I am under the impression Just Dashes honors quality call-backs, but it's within a fairly short period of time, think it's like 30-45 days, just FYI.

I was thinking I should have shot the exposed metal frame areas with a flat black, might want to consider that. It can flash rust and the edges can lift.

Only thing that does not fit too well is the knee guard., a bit of lubricant should slide right in.

Still in paint jail, so time to work on the dash. I ordered American Autowire Retrofit kit #510-540, this kit is under $700 and does the whole car except the tail light harnesses. The quality is superb, and the main thing I like is uses a new fuse block with blade type fuses and plenty of extra circuits. I found I needed to mod it a bit to work with what I need but AAW supplied many extra pieces and sub-harnesses to work. I eliminated a couple of those by simply wiring the gauge cluster direct - cutting the wires to length and soldering in the connectors and snapping them into the connector plug.
Other unused circuits were re-purposed for such things as Wiper delay speed wire. I found that by flipping the dash upside down and supporting it with a couple of caliper boxes the steering column can balance it, allowing the column harnesses to be fitted on the bench - far more comfortable!



I mulled a different setup for the Delay wiper, but could not find a suitable place for the timing rheostat - so I went back to the original setup. This is a 1978-81 Regal switch, but I note the 1981-88 Cutlass switches can be modded too. Originally I epoxied a pair of metal "ears" to the switch but found they fell off after time. I now fabbed a clip from some 22 gauge lying about and it worked perfect and is reusable (right on picture).



After the dash harness is completed and tested I will rebuild the steering column - a task I am not looking forward to one bit.

Mind providing some more info on this particular setup that you're using? I thought most GM cars had gone to turn signal mounted wipers by 1979-1980, how does this switch look from the front and does fit original-style or is the front bezel modified? I've been wanting to add these to my '72 for a while now and haven't been able to find a decent OEM switch that will fit the hole.

I am using the 1979-81 Regal switch modified. That said, an easier way to do this is the run a 1 meg rheostat as shown:

Started pulling the steering column apart - much easier than a tilt unit. Upper bearing has at least 0.020" slop in it - horrible design.
I ordered some UHMW tubing and a pair of thrust bearings from McMaster - I plan to make a bushing and think it should work fine.

Good ol' GM cheap ass snap ring...



turn signal switch...



pressing out upper bearing.



Other issues to deal with are an absurdly loose key (locksmith time?) and a non-functioning key buzzer. This short video shows a couples of quick fixes for those two issues

I have been extremely busy with the day job, so work on the LeMans has slowed down a bit. The upper bearing in the steering column was vexing me, so I fabbed up a piece of UHMW and a pair of roller thrust bearings - works quite nice. I may sell them as a kit as I see no replacements available.

The Custom Sport steering wheels have issues I am told so am going another direction.

Body shell is on parole from paint jail. Not going to bore people with endless shots of primer and bondo. Painter shot jambs and trunk area. I will mate it up with the frame after installing the FI gas tank.
Will go back to jail in 2 weeks as painter want to assemble the tin.

Have to figure out what to do with trailer now...
