Hello all. I am adjusting my kickdown band and rear band on my small block 727. This is the first time I've ever done this. Tranny is dated coded 1972. Tranny operates nicely (and fluid looked perfect) except right now I don't believe I have any kickdown at all (and yes my kickdown lever is...

I recently changed oil and filter in my 340. When I stored old oil for recycling, I had gotten a little less than four quarts from engine/filter. Oil level on dipstick read full before change (That's odd. Will check accuracy now I know there's 5 quarts in it). Stock oil pan. 340 was refreshed...

Easy question but one I can't nail down an answer to. On this chart, the measurements shown are center of yoke/ujoint to center of yoke/ujoint. Correct?

I'm installing a tranny cooler for my small block 727. I'm going by the FSM, with fluid going to radiator first, then to aftermarket cooler, then back to trans. The book shows the pressure or hot line (the front port on the tranny) going to the drivers side port in the radiator. In my lines...

I'm not getting oil through my rocker arm squirter holes on left side. It's a 340 with 273 adjustable rocker arms. Right side squirts fine. Oil is definitely getting to the head. I turned it over without rocker arm on and oil poured from second rocker arm stand. I have it installed correctly...

This might be a stupid question, but how soon after priming the oil pump/engine (340) on a fresh rebuild does the engine need to be started? I've read conflicting reports, from 15 minutes to a couple of days. Does oil pressure suffiently hold for a while (like between normal starts)? The issue...

I'm reinstalling my 340 after getting some work done. I marked the flexplate and 727 converter with a little paint before I pulled motor so I'd know the proper alignment. Now when I put "marked" bolt in, the others aren't lining up. Two line up (including one with paint) and other two are close...

I need different pushrods after changing cam, engine work, etc., in 340 with hydraulic cam and 273 adjustable rockers. I used pushrod length checker to measure all 16 pushrods twice for correct length. Shortest -- 7.307 inches Longest -- 7.363 Average --- 7.339 Do I order the shortest length...

I have 273 adjustable arms on my 68 340. During my winter refreshing, I noticed I only have one oil hole under each rocker. I've seen posts that lead me to believe the stock 273 arms had two oil holes per rocker. I've also seen some threads about drilling a second hole to improve oiling to...

I am putting an aftermarket harmonic balancer on my forged crank 340. The Summit balancer instructions say to torque crank bolt to 95 pounds. FSM says torque to 135. Normally, I'd follow the part's specified torque spec but this is a significant difference. I called Summit and they said their...

I just did my first leakdown/compression test on 340. 11-1 motor. Did test with 90 psi at TDC at operating temperature (although motor obviously cooled down a bit during 2-hour process). Motor runs strong but was getting some blow by. Here are the results #1 170 compression -- 2.5% leakdown #2...

I am getting oil squirting to underside of hood on 340 above PCV valve. Only happens if I drive more than 5-10 highway miles. Short trips around town don't leak at all. PCV valve is good. I have a breather with hose to air cleaner base on other side. It's not a lot of oil. Probably a half...

I've got a stripped header stud thread in the head on my 340 and plan to use a helicoil to fix it. I'm have a lot of room to work. It's the outside stud next to No. 1 cylinder. Headers are off car. I'm going to use grease on the 90 degree angle drill bit to catch most of shavings and try to blow...

When I touch the primary accelerator pump while at idle, my engine bogs and almost stalls. 340 with an AED 750 double pumper. Runs terrific with no off idle hesitation. But I've heard that pressing pump shouldn't affect idle if carb is set up perfectly. What -- if anything -- is this telling me...

Who here has used the rear servo port for an aftermarket tranny temp gauge for small block 727? I am installing one and trying to decide on the pan or the rear servo port. Also, does rear servo port measure fluid temp at all times or only in certain gears? Thanks.

I know this topic has been dealt with a lot (but FSM is a bit fuzzy, at least in my eyes) and was looking for some help. 72 RR w/ 340, 727, 3.91. I swapped carb and manifold and need to get kickdown dialed in. Right now I am getting a slightly delayed upshift from 2-3 at normal throttle (about...

My 340 is set at 18 initial, 34 total, all in at 2500. Today, I used a vacuum gauge to see what timing my engine "wanted." I rotated distributor to get max vacuum (about 15 lbs), and when I checked, damned if my initial wasn't at 40. It idled well there (idling at about 850) and didn't appear to...

Let me start by saying I'm likely in the bottom 20 percent when it comes to Mopar troubleshooting among everyone on this board, so bear with me if i sound simplistic/stupid, but I really hope one of you guys can help me. I can't get 340 to stay idling and now carb -- which I jist rebuilt -- is...

First off, I want to thank everyone who has helped me on this board. It's the best site on the web, bar none. Here is my question. I just put a timing light on my engine for the time since I re-purchased my old car from college. 340 was running fine but wanted to know where I was at. I was at 6...
