brought my elco to Lars for a distributor rebuild and ignition and timing.
kept crane wires and coil. checked coil hot side was not receiving full voltage so no need for additional resistor.
said distro was very sloppy; has a Sun machine so he sets them up right. also vacuum advance wasn't correct so he swapped in the correct vacuum advance thingy. he sets you up with points; only way he does it.
changed vacuum advance from ported vacuum to manifold vacuum.
initial timing set at 18°
full advance 36°
also adjusted/replaced some of the springs and weights along with new vacuum advance so that 36° comes at about 2800......it was about 3400 rpm/
i also had a cold start with the Quadrajet where it was just too rich under choke. he adjusted it to '13 to 1' ???? so not as rich on choke.
found accelerator pump was 'funny' so he replaced that too.
drives like I expected it should have from day 1.
Lars sent me an invoice with the details of the tuning and work he performaed:
remove Electronic conversion
correct Excessive shaft endplay
remove Slop in breaker plate attach point
replace No lube in upper lube well
Curve too slow
Vacuum advance too stiff and long for application
Choke pulloff too rich
Accel pump swollen
Curve is now:
20 degrees centrifugal advance
Curve starts at 800 rpm
Full advance all in at 2800 rpm
Dwell set at 30.5 Degrees
Set timing to 16 degrees below 700 rpm, or set for 36 total
Vac advance starts at 7"
Full vac advance 11 degrees at 11"

Hi Perf Points
B-26 Vacuum Advance
VAC Advance Limiter

Lars' details of his distributor fix:
Distributors: I only do the rebuilding on the stock GM points-style distributors (including Corvette tach drive) - not HEI or TI. If your points-style distributor has been converted with an aftermarket electronic conversion "kit," I will remove the conversion and install a set of high performance points: The aftermarket conversions are the source of a multitude of distributor problems, so I will not use them. My points will outperform any aftermarket e-conversion. I will return your e-conversion parts to you in a bag. I cannot test distributors with the e-conversions in them, so I cannot verify operation or curve unless the distributor has a good set of points. The base fee includes a complete teardown & inspection, hot tank, cleanup, paint, detail, a precision assembly with my KwikCurve kit (includes new vacuum advance control unit, hardened shims, custom calibrated springs and a custom advance stop bushing), new high performance points, new condenser, and actual running of the distributor on my Sun distributor machine to verify advance curve and performance through 6,000 rpm. If the distributor needs other parts, such as shaft bushings, cross gear, main shaft, crossgear thrust surface repair, etc., this is in addition to the base fee, and I charge my cost on these items. I also charge a nominal fee if the tach-drive distributor housing needs to be machined due to cross gear damage and if a custom thrust button needs to be fabricated. The distributor is supplied to you with complete installation instructions. Do not ship the distributor with the cap or rotor, as these will get broken in shipment."
I sent a set of control arms and rebuild parts to glenn lever
had a gm chassis color match powder coating applied.
did the shafts in grey.
moog ball joints.
AC Delco Professional Rubber bushings.
and a few months later we pick it up with ........
and following up on that post above I have been collecting parts for a complete suspension job
the front end is very sloppy when driving. a mess. looks like nothing but sway links and shocks have ever been touched.
I have been accumulating parts. i wanted to stay mostly original in look however I want to DRIVE it.
