    Tume an A727 to it's torque converter?

    Do I need a lower stall converter, or can the 2-3 shift be dialed in? When building the chassis, much of the weight was guesswork and a torque converter was purchased to those numbers. It's stall (advertised) is 2800 rpm. 440 has a mild cam and the rear diff has 3:55's. Total weight with two...

    Don't know what to make of this

    440 rebuilt, sat for 20+ years on an engine stand. Regularly rotated on a set schedule once a month. Oil has always been Chrystal clear on the dipstick. Break in at 2000/2500 rpm for 30 minutes. Engine running fine at 185 deg. After the engine sits for a few days, there is a dark grey substance...

    Z D D P

    Let's go back in time. The year 1977. The example vehicle is a Jeep CJ7 equipped with a carburated 304 V-8. Engine tolerances have not yet transitioned to the tight ones experienced today. Let's say the Jeeps' cat has been removed, the engine is bored, heads decked, 4 bbl intake installed along...

    Valvetrain clatter/noise

    Since this is my first attempt at building Ma Mopars biggest, I'm very unfamiliar with the way this big hunk of Iron is supposed to sound. I've run a compression test (dry/cold-5 revolutions) and all 8 register 150 psi on the dot. 40 psi oil pressure cold at start, drops to 35 psi warmed up. I'm...

    Timing chain cover timing indicator

    This is a 1968 block with what I assume to be the correct timing chain cover. The lower radiator return outlet is above the timing indicator. Is this OEM? I can't see the marks from up top, but can see about 1/2 of the mark on the ballancer. At this point, my timing is guesswork. Did the builder...

    Header gasket/leak?

    I just did a compression check on my 440. The cam has just been broke in and I have timing and carb set to where it's running smoothly. All 8 @ 150 psi. Due to this engine being so loud, it's difficult to diagnose a constant tick that can barely be heard above the noise. My guess is a leaking...

    OK, Wizzards

    1968 440, .030 over, 480/480, 230/230 @ .050 109lsa. Valve springs are Sealed Power w/100 closed/286 open. What available modern day camshaft would work with this 26 year old technology? I really don't want to be changing valve springs should a cam failure occur. This engine was rebuilt 26 years...

    Fast Idle RPM'S ?

    Hey all, at a loss as this is my first big block Mopar build. What should I set the fast idle rpms to.? The factory settings on the 750 cfm quick slayer put the rpms close to 2000. To my ear, this sounds way to high, and I'm getting slight lifter rattle on cold start. The 440 is basically stock...

    Any Idea?

    I've got a Ford steering column in my PT-105 that uses this ignition switch. Any guess as to what the metal clip is for? Obviously, the harness connector can't be installed with this in the way. Thanks in advance. My apologies moderators. This was posted in the wrong section. Can it be moved?

    Let's see what you've got

    I'm one for detail. I like clean engine bays, with even the wiring and hoses planned out and placed athletically. Of course, beauty is in the eye of the beholder. Now's your chance to show them off. Mine is in it's infancy. But she's looking good! P.S. Whatever you post, I may copy! And a...

    Harmonic Ballancer

    Just curious. Is this a stock balancer, or has it been machined down? The engine has a forged crank, and is internally balanced. 1968 block. Apologies for the misspelled title...

    Someone Here Might Know

    I realize this forum is for bad-*** B bodies, but I've spent countless hours on other forums trying to find an answer as to wether an old transmission I have is a 3 or 4 speed. It's out of a 1941 Dodge WD21 1 ton pickup. There is a casting number on the shifting plate - C35661. I read on...

    Lifter tick after break-in

    I think a cam lobe is wiped. We didn't have time to pull a valve cover to investigate. Checked the setup and the engine started immediately. Brought it up to 2000 rpm and let her rum for 20 minutes. Temp reached 210 deg and stayed steady. No pops or backfires while running, but the was a barely...

    Pure Guess?

    My first post here. I had an engine builder put a 440 together for me. His only question at the start of the build was what the engines' main use was. I told him it was to be run on the street with a very occasional trip to the track. Two weeks later I got a call from his grandson, stating that...
