    Why does engine cut off after idling for awhile?

    On this 65 Valiant 170 I've got. It starts up easy and idles good. It's got the most vacuum I can get out of it for it's wear and tear. It's between 16-18 in-hg at idle. It appears the motor has some miles on it but it idles smooth and no unusual noises. All electronics have been gone through...

    I'm debating changing the oil pan gasket on my 65 Valiant 170 because it's really nasty. I've already changed, intake/exhaust manifold gaskets, valve cover gasket, timing cover gasket, oil pump gasket. I've got the factory manual and it says you have to remove the center link and raise the...

    What will cause slight miss idling on a 65 170?

    I've got the backfire through the carb situation taken care of it seems. I believe it was a carburetor gasket with a vacuum leak. I installed a new gasket today and I was able to rev up the engine with no more backfiring. It starts fairly easily seems to have reasonable power but I just drove it...

    How do you successfully install intake/exhaust gasket?

    Ok my intake/exhaust gasket was leaking vacuum on my 65 Valiant 170. So I decided to replace it. I took everything off replaced the gasket and now it sounds like a tractor. No more vacuum leaks or sucking in air when I spray around the manifold but it's louder. So something is misaligned or...

    Changing intake gasket on a 170, any tips?

    I've got this 65 Valiant running pretty good considering it has an intake manifold gasket leak. I put a new gasket on 2 years ago when I got the car but never have driven it on the road but started it a few times. It's leaking now. It's hard to start up. I'm guessing that has something to do...

    Are there any easy add ons to make more torque on a 170?

    I've got this 65 Valiant with a 170 that I'm getting finished up to put back on the road. It's by far not finished. It's stock inside as far as I know. The motor is a 1966 170. It's got a Holley 1920 and stock exhaust and points ignition. I know the small stock air cleaner was restrictive so I...

    How easy is the Offy Slant Six manifold 4bbl setup?

    I've got a 65 Valiant 4-door with the 170 Slant Six that runs decent with the Holley 1920 1bbl. But I want a little more kick if possible plus I may want to add an underdash A/C.

    65 170 idles ok, starts ok, pops through carb

    After sitting awhile outside my 65 Valiant with a 170 finally started up and still idles like it should. About 3 or 4 months ago I installed a remanufactured carb, reman distributor, plugs, wires, cap, rotor, coil. I set the timing to 5 BTC and it's still on that same mark today. Even when I...

    Getting slant six started

    This 65 Valiant has been sitting for 2 years outside. The engine has good compression and I don't believe there is any issues with it. It appeared to have been either replaced or rebuilt when I got the car. It's supposse to be a 225 in the car but it's actually got this 66 170 in it. I didn't...

    Emergency: Trying to change oil pump on 65 again

    I tried this last summer with no success. It's a 170 65 Valiant. I was changing the RH motor mount and didn't know the condition of the oil pump or the actual mileage so I wanted to go ahead and change it. Me and a friend battled with it for a couple days each hours a day. I tried doing it...

    170, curious about Offy 4bbl Conversion

    I noticed there is an option for an Offenhauser 4bbl aluminum intake and they also have the linkage kit for a cable operated transmission like my 65 has. Has anyone here successfully tried this conversion? I read the articles about doing a Hyper-Pak or Super Six 2BBL conversion and I've read...

    Is it possible to do a Super Six to a 65?

    I know it will be too difficult to do a Hyper Pak. But on this 65 Valiant, we're pulling the motor to do some engine bay work. The motor is a 66 170 running good, but just a stock setup 1bbl. I know it won't be anything major but I've got a 2bbl manifold and was wondering if I could make it work...

    Oil pump change impossible on 65 Valiant 170

    We tried all day to remove the oild pump on my 65 Valiant with a 170. We got as close to as the pump shaft was completely out but because we couldn't tilt the motor any more at all it did not allow us to lift the oil pump out of the car. It's still too close to the passenger side frame. We tried...

    What size are the cyl head studs in a 170?

    I was finishing up the cooling system repairs on my 65 Valiant that has a 170 slant six in it and I got to the point of adding the coolant and of course it shot right out of the head. I thought I cracked a block in the hard freeze we've been having. But I looked at where it was coming from and...

    Adding power steering on a 65 A-body

    So where could I get the brackets and power steering parts to add factory power steering to my 65 Valiant? It has manual steering. Would I have to change anything on the steering column? I saw a 73 today with all the brackets, federal pump, and gear. Would that work?

    Is there a correct break in on a re-ringed engine?

    Ok I like to get all the opinions as possible on my break in of my big block 400 in my 73 Charger. Eventhough this is a Slant Six column, I'm sure some of the tech probably applies to all these Chrysler engines. I'm almost finished up with my 73 Charger and then it will be ready to roll it...

    Oil for a Slant Six that's been sitting a long time

    I've got this 65 Valiant that's been sitting for months since I've acquired it and years before that probably without running. When I first got it about 6 months ago I was able to get it started right up after a carb rebuild. The engine ran, didn't smoke, and didn't make any unusal noises. The...

    Mild bolt on performance for a 66 170CID?

    I've got a good running 66 170CID in my 65 Valiant. I was contemplating doing some minor performance enhancing upgrades to help bump up the HP from 101 and the torque from 155LBS-FT. It's got the factory Holley 1920 with the rod type throttle linkage. How easy will it be to swap a Super Six 2BBL...

    Is anyone making the forward light/engine harness for the Slant Six 65 Valiant A-bodies? The one at Year one that says 65 A-bodies is actually for all the V8 engines not the Slant Six. Can I use the short Mopar oil filter for the Slant Six or do I have to use a tall filter?

    What's a nice HD ignition wire set?

    What's a nice set of ignition wires for the 65 170 Slant Six? Not necessarily restoration wires. But maybe some heavy duty other than the $12-$20 cheap ones at the parts store. Accel had an exact fit set 4061 but have been discontinued. They have a new number replacing it 4021 but they are no...

    65 Valiant 170 changing RH mount and oil pump

    Is it going to be impossible to change the RH engine mount and oil pump on my 65 Valiant 170? The LH mount was easy when I was changing the intake manifold gasket. I didn't even have to use an engine hoist to raise the engine up. I've got the 65 chassis manual and it says you have to raise the...

    How do I reinstall my timing damper without a threaded crank?

    How am I going to reinstall my damper on my 170? It didn't feel like the crank snout was threaded inside. It's a 66 170 motor. The engine ran smooth with this damper on there but it defnitely isn't new. I had it carefully bead blasted and repainted. The machine shop guy said they use to just...

    Identifying my engine

    My Valiant is a 65 4-Door which originally should have had a 225. But when I was installing points today I noticed the stampings behind the coil. It says B 170 04 27. I came up with a April 27th, 1966 170CID. Is that correct? So my Valiant no longer has the correct engine. Even the carburetor...
