Just finished working on a 200 6 cyl with a Holley 1946 carb out of a 1979 Faimont and I must say this setup seems to work very well in the EB. Has all the grunt of another 302 I have, of course this 66 is stripped of weight.
The 200 was full of smog stuff that was easy to defeat, yet still had "newer" six design for parts.
EGR plate is required unless you fab up a mounting bracket for carb, I just hacked off the EGR diaphram and JB welded the hole shut, stopped all leaks. Rebuild was easy and I bought the manual for a 1946 just to be sure, easy peesy, lemon squeezy rebuild. Adjustment was just as easy, electric choke hotwired to alt hot, then make sure dizzy hooked to metered air.
Idle mixure was all in then out about 1.5 turns then final set using rpm/vacuum plus 1/4 turn for luck. I notice no dashpot for throttle return, I may want one of those later.
On this carb the hot air inlet by the choke assembly was plugged, I may add that as the hot air bypass aids hot idle (sorta like how EGR helps cruise gas mileage).
Base advance set at 6 degree's like old 6 cyl 170, idles like a kitten purring.
Only issue to work is throttle cable/bracket, since I hacked the egr plate, throttle cable bracket lost one of two attchment points... Still cogitating a fix.
Engine runs at 190 deg at water thermostat exit and 140 water temp inbound to motor, gage shows pegged when warm so that needs looking into, I think sender is off 79 Fairmont.
On an unrelated note, anyone have ideas to chase a "squeel" during cruise above 1500 rpm, sounds like somewhere from tranny area, noise stops when clutch let out and is not there at slow speed. Sounds like a slipping belt but not there when rpms hi with clutch out, Don't think it's a wheel bearing.
