fred on page 10 you indicated your idle was 17afr  that is way too lean it has to be pretty rich at idle around 13afr the rest of what you had doesnt seem too bad except secondary jet may be  a bit fat  my car works best with 13.5 afr idle about 15afr cruise  12.5-13 wot. on a 750 vac secondary carb i had to go  to a 37 squirter and  orange or green pump cams blue will work but only in 1 position i could not slowly move from a stop sign without  running out of fuel i mean driving like a grandma  your carb is much bigger and i would think it has less signal and demands more fuel off idle from pumpshot and more fuel from the transfer slots to transition from idle transferslot then main jet i wouldnt  worry about ifr unless you cant get  to 13afr  your plug gap will take care of smog issues  i run mine at .048 gap  this is why new cars have emissions systems and smell like a dryer vent! also disconnect vacuum advance until you get other stuff sorted out!

all very good points  but  i think he is asking"barrett jackson" prices  for something that fell in his lap! the only big dollar parts are intake,carbs, exhaust headers oval air cleaner and block. everything else is meh. small valve heads cast crank good stuff but meh BTW i live 4 miles from chevy engine plant i really think i was hitler i my former life :(

Apparently this motor is supposed to have  30000 original miles on it never saw in person but did see  intake and cast iron headers looked good his price seems or he seems high at  10,000 especially in pieces!!

hi bob, i have  a duraspark distributor that is hooked up on manifold vacuum i cut a piece off another advance pod  and attached  with 4-48 flat head cap screws to adjust the amount of advance. the early style pod in your picture wouldnt fit but is a better piece from a tuning standpoint. i set the timing to 16-32 adjusted rod to give additional 6 degrees at idle and 38 all in . if this shows some improvement maybe slow the timing curve down some? i remember joe craine mention something about slowing the advance curve to help an engine rev smoothly. my car at 60mph is around 28-3000 timing is all in at 3000 maybe go to 3200,3400. the only time the engine gets cold is  when the outside temp is below 70 degrees and dont have to stop for 10 miles at 60mph or so. heads are pretty warm rad is luke warm it is running like when it s almost ready to back out of garage! when driving in town it stays in  normal operating range no problem! anyway bob thank you very much for trying to help !

thanks again guys! i sure wont put 87 in anymore but it was an emergency! what was weird was air fuel at idle went up from 13.5 13.7 to 14.5 or more. i kinda wrote my timing stupid my initial timing is 18 with 34total vacuum gives another 12 at idle gets vacuum to 15-16hg carb is a 3310 cheapie no dash pot like the 600 oem carb but what you were saying about it sticking: i was thinkin about were the vacuum pod letting off and mech timing going up may have crossed early or high and caused pinging ? maybe? but im not gonna do  that again i was showin my brother how his 351c 4v is inferior at layin rubber from 10 mph than my boat anchor \ dumptruck motor. my real concern was the engine gettin cold on the open road. imean its acually running like 3mins after  starting it  no temp gauge needed   it is cold and spittin the rad is luke warm drive at 30 or 40 for a while it warms back up never had any problem on 80 or 90 degree days  just on 60 to 70 degree days when you want to take a cruise ! could it be timing 46 all in  or do aluminum heads lose that much heat?

heo meant the rocker shaft springs from stock rockers  i found suitable pair at sears hardware an old time hardware store usually has a good selection of springs home depot lowes not so much!

looks like a6 is your straight up!  goes to show how important it is to check your parts ! if this happened to me when i built my motor i would have been screwed there was no fe forum i could picture myself in the garage staring at the wall wondering why i didnt do an ls motor. NOT!!!! anyway good luck! that thing will be a bear when your done !

ok, ran new thermostat today. little bit better but not what it should be. i think im gonna back the vacuum advance out  12+18+34 at idle down to 9+18+34 total i did find i am somewhat close on timing though  i needed gas asap had 10 bucks so put 87 octane in instead of 91 from 25mph roll 2nd gear acceleration  gave me preignition 3! rocks in a can! outsandingi never thought this engine could do that ! been running 22 years  and never could get it to ping on 89-93 octane sunoco at least i know my timing curve is close to optimum!!!

thanks guys  got a new 195 starts to open at 195 drilled 1 .062 hole in it installed had to help brother do water pump on  3.5 doch taurus  under timingchain cover really !!!! hope my ranger lasts 179000 it wont be mine then! well see what happens sunday!

i have to chime in on advancing cam timing i agree 100 percent on my 390 i went from 106 icl to 102 icl 160 psi cylinder pressure to 185 and gained 3 or 4 inches of vacuum ! runs much better now . on the 3.5 pv is too late  if you drive with vacuum gage attached you will notice you have to get in the throttle abit before you need anymore enrichment you want to start opening the power valve in anticipation of a lean condition not after it occurs! but dont dwell on this until the other stuff is sorted
