Hey guys, Im looking for pictures of the correct throttle bracket, return spring bracket and kick down linkage for a 73-340 or any thermoquad equipped 340. The stuff I have puts the kick down linkage at a weird angle and binds up under full throttle.

So Im sitting at home on another rainy CT weekend dreaming about someday finishing the car and building the ultimate motor for it. My ultimate goal with this car is in this order. 1. Look mostly stock, under hood, interior and exterior need to look like a stock 340 Dart to most people...

I thought this could be an interesting topic. With gas price just about at $4.00 a gallon in CT and my trucking getting about 12mpg I have a feeling if I ever get the Dart together it will probably get better millage then my Dakota. So if you were to build a car to get great gas millage how...

I would like to keep it pump gas friendly so under 10:1 ? Cam, should I just go straight to a solid roller ? It needs to sound stock so Im guessing 112 or 114lsa and maybe 220-230 @.50" tops ? What about heads ? Im thinking a port job for this type of build is going to be a lot different...

I found some interesting looking street/strip cam grinds on Crowers site Anyone run any of them 31916 269/282 223/234 .480/.494 112lsa 31242 271/284 222/234 .485/.498 112lsa 31243 282/292 227/237 .480/503 112lsa 31204 280/292 218/227 .474/480 108lsa 31205 290/298 224/234 .507/522...

Does anyone have any experience with the modifications out lined in the Mopar engine books for the LD340 intakes ? These mods are for running spreadbore (thermoquads) and cutting down the divider. I'm going to be running a TQ from Demon Sizzler and Im debating if I should try the other mods as...

or at least my idea of it. I really want to build a nice street/strip package. Nothing super fancy, nothing super fast. Looking for low 12s, (dont want a bar in it) , good torque and mid range, good throttle response. This isnt a daily driver but a weekend street toy. The car is all steel...

Why does something so simple end up being a problem. First i dran the oil and pull the filter. Simple. The oil that came out was full of fuel from my earlier carb problems. I should have changed it MUCH sooner but didnt. Then I go to put my new filter on (K@N) and it wont go on. I messed around...

Has anyone used these yet ? Im wonde how much needs to be milled to use them with closed chambered heads and if you would use them again ?

Has anyone ver retro fit a late model magnum F.I. set up in to an older car. I see lots of cool parts for Dodge Trucks with 5.2 and 5.9s that would work in an older car too. I wouldnt mind having this under my hood

I was looking at the Mopar Performance crate motors and something didnt seem right. First I looked at the 9:1 Magnum block, Mopar says it has a 1.67 Compression height So I do alittle math. 1.79 (half of stroke) + 6.123 (rod length) + 1.67(compression height) = 9.583. No subtract that from...

My turn for the what will it run. 3200lbs all steel. 340 9.5:1 compression Magnum heads Airgap intake 1" Super Sucker spacer CompCams XE274H 230/237 .513/.523" with 1.6 rockers 110LSA 650 Double pumper 1-5/8" headers 3" exhaust 904 with 2.77 low first gear, tight 3800 rpm...

Anyone know who makes 340 pistons that can be set up at zero deck ? The KB sit arouns .020" above the deck so they wont work with my closed chambered heads. Or I can go for the KB107s for a 360 and use a mopar perf. 3.58" crank.

I may have a problem with the new truck. Ran out this afternoon and when I looked down at the oil pressure gauge it was sitting at 22psi under light load. at about half to 3/4 throttle is goes up to 40 psi and idle is only 18 psi. I can also hear a slight ticking probably valvetrain but its...

Im trying to put together a list of parts that work on these heads. Valvesprings, Rocker,valve covers, valves. Anything that will interchange from other makes and models. My reason for this is because Im going to be swapping a set on my 340 soon. Im running a CompCams XE274H and Im having a...

I need a set of valve springs for magnum heads and a XE274H cam. .513/523" lift with the 1.6 rockers Will the R/T or 6062 spring work ? Will I need new retainers. Comp recommends the 995-16s but they wont work with these heads.

Is it worth the time and effort to gasket match the ports,clean up the bolws and polish the chambers on my 1.88 valve J heads ? Ive never messed with heads before and dont want to go crazy and ruin them, but I figure while they are off there may be a few ponies in there. Its a pretty...

I just picked one up. 230/236 .488-.491" lift 110 LSA. I think it will work pretty well in my car with the 3.91s and 10" converter. If your running one how do you like it ? Im hoping it has a ton of mid range pull to it.

Ok my car is starting to look like a full on drag car. I really need to update the 340. Id like to get it in to the mid 12s. Can anyone recomend a good combo for me? Lets assume the 340 is currantly stock with nothing other then an LD340 intake and headers. Im running a 727 and an 8-3/5 with...

What RPM do you shift your 340 at ? I was playing around with desk top Dyno and built a 340 with a set of ported RPM heads, 10.5:1 compression and the XE274 cam your using and got 462 horse at 6500 rpms wich means youd be shifting at close to 7000 rpms. Does it really pull that high ? I...

Im thinking about swapoing in a new cam. The motor is a 72 with a stock bottom end as far as i know it still has the low 8.5:1 pistons in it but I think the heads may have been milled alittle. The currant cam is stock also I think. It idles with a little lope at 800rpm and pulls hard from...
