165 should run on 91.the 340 in my dart is 10:1 and cranks higher than that.ive got no problems running 91 with 34* total timing and 22*initial.there are 2 things that come to mind,timing is advancing further at higher rpm(like cracked said) or you have carbon build up.

notice i said vac secondary holleys,you can adjust the secondaries so the engine only draws as much as it needs.if you can tune a single carb set up well,a dual carb set up is not that much more difficult.for linkage i used a universal t-ram linkage to link the carbs and combined it with a lokar...

tunnel ram would work well here.my set up is much milder that yours and it runs well.i can honestly say that the eddy street ram currently run on my 340 makes more power than any other intake ive run on it...and ive run a few lol.a close second was the eddy air-gap which seemed to have a little...

its at 170 with ONLY ONE PLUG REMOVED.and it gets there right quick.if i pull them all to let it spin faster i imagine it will bump a good amount higher.firing order is good,and i know its not lean,i tried making it fatter and it still pings.im not sure i mentioned this but under normal driving...

they are both there.i took it apart and looked looked early on in my investigation.

yes im sure.

so what would be the correct rpm for full advance with a stock dizzy?

i already ran it with the vac advance disconnected,it made no difference as well as tried water down the carb to de-carbonize...also no change.

not at the moment,its got a stock electronic .thats the first thing i looked at was the advance curve.its all in by 2600.and its got 24*of mech advance.the 170 psi is if i remove 1 plug randomly.it would have more i think if i removed them all.

agreed,and i just pulled a valve cover.i looked up the p/n and the has an 88 cc chamber.p/n is 3769902 which is a 74 440 head.the block says 4T 440 T, and is dated 74 on the side.

tried the water trick for carbon...no change.ill back with head casting numbers.......

thanks for the replies,ill try the water first to eliminate carbon,if that dont work its time for some high octane fuel.be back later with the results and some head casting numbers. to be continued.........

interesting.....it has no problem like you are describing with overheating,or general driveablity.it runs and idles very well,and has no detonation under part throttle conditions.pulling the heads had crossed my mind,but only as a last resort.

im a little stumped on this one.my 340 dart has the same cranking psi,and it runs on 91 with 20* initial timing and 34 total.and is all in by 2200-2400.however the cam is pretty long in duration (284).

the plugs are autolite 85 which is the correct plug for an hp 440/383.the advance is all in by 2600.i thought about welding the slots in the dizzy,but still,having to limit total to 22* ?ill check for carbon build up.

im running 91 premium pump swill lol.high octane race gas is the only thing i have not tried.i considered swapping cams to the 440/383 hp cam.

well im now the new owner of a 72 d100 se .it original 400 has been swapped to a 440 which wears hi-po ex manifolds,and judging by the balancer has a forged crank.other than this the engine is an unknown ,the builder is 6 feet under.the problem im having is it pings under full throttle no matter...

if the price is fair id say yes,if you dont use it i dont think youll have a problem selling it.

you can see pics in my photo gallery under my user profile.sorry they are not the best .

thats what im running with the 450 holleys.i paid $140 for the manifold and it really has great low end response.

x2

im running an eddy t-ram on my 340.its very streetable,but required some tuning to get it right.before swapping intakes i was running an rpm air gap and a 650 dp.i lost a little low end but not much.midrange and top end are excellent.the main changes i had to make were advance curve/initial...

it really depends on how its set up.a holley,carter,or edelbrock can all give the decent mileage/power if tuned correctly.ive had good results with TQs,but they can be a pain to tune.

both should work fine.i ran a 650 dp on my 340 with goods results.the new summit carbs are basically a holley 4010,and they come with annular boosters which help atomization/throttle response and i think they have a 750 cfm version they sell for a good price.

if you convinced you want to run a purple cam in you combo id run the 268/272 450/455 lift 110 lsa.jmo.if your looking for a lopey idle and still keeping it streetable go with a consevative grind with a narrow lsa,like an isky 270 mega (270/270 465/465 108 lsa) or maybe a comp 262XE.ive run...

i agree with the above post.id run a little smaller with your combo.also,what kind of idle are you looking for?you heard the clip of DJV CUDA.its got a pretty healthy lope,and thats in a 360.the idle would be rougher in a 318.a custom grind is worth the extra $ imo,schneider,and isky have made...

what cam are you running now?what kind of rpm range are you looking for?

whats the rest of your combo like?gears,intake,stall speed,compression ratio?as you know these facts will have a bearing on if that cam will work well for you.i almost ran that grind in my 340.i have a very similar set up as DJVCUDA in my dart.i ended up using a custom grind after i had the...

we had a 73,4dr,318,valiant for years.was my wifes daily driver.it had a mild cam and 4bbl as well.we live in the stix an got alot of crappy roads so i kept the manifolds on it for ground clearance.the cheap headers are a pain to install,and the drivers side hangs low,it can get crushed very...

i did at one time...replaced it with a 340.my 318 did not have good street manners it had a large cam and 340 heads.it would wind up really hard but sucked to drive in stop and go traffic.it needed more gear and more stall than i had at the time.although i did have alot of fun with it.im alot...
