Accurate Limited Exhaust has factory style pipes to install on those manifolds. If you order, make sure that you have the casting number off the manifolds since they will ask to be sure of sending you the correct piece. Excellent fit with no beating and banging...

if you don't like the look of the connections between the functional pieces of the gasket, install them and then cut the offending parts away. IMHO, I absolutely cannot imagine installing those manifolds on heads with nothing in between. Wouldn't any little imperfection in surface and...

As above, there you go! Use them under all the bolt heads and nuts that they fit under. The sleeve nuts themselves provide a wider bearing surface on the manifold than bolt heads or regular nuts. I have never used the sleeve nuts in the form of studs and then sleeve nuts. When I got my bolt...

yeah, you can leave the conical washers off the center port bolts, but at $500-800 for a pair of these, I sure wouldn't risk busting the ears off of my manifolds in the name of what is supposed to be "correct".

Closest I could find from existing photos... this is one of the reproduction bolt/nut/washer kits and was identical to the 50 year old bolts that came out. By the way the cone washers are to change the pressure of the nuts and bolts on the fragile cast iron "ears" where the manifold mounts to...

The studs on the ends (drivers and Passenger)are into the water jacket (it's why they use studs there) be sure to seal the studs when you install them. They sell a new set of all the correct bolts, studs, washers you need for both sides...

I remember at the ripe old age of 19 installing my first headers on my Dart, taking it to a pipe shop and having them install tailpipes like that... maybe even longer. Long enough that every time I walked around the back of the car I barked my shins on them :lol:

Don't know how far you moved your springs, but for the 3/4 inch shift (see offset shackles) all it took was a longer bolt for the hanger and a wad of fender washers (wide to make it stiff). By the way, these are the "right" tips for your car - long box, short bullet - designed for...

yeah, the answer to your original question is YES! install them AS you are setting the engine in place. depending on the design you might have to break apart the connection for the tie rod, so figure it out and do that work while you can still crawl into the engine compartment without the...

For a street car I think you are headed in the right direction - you will never feel the difference between a set of headers and 340 HP manifolds with good duals and like you say the manifolds are a lot less headaches on the street. Without a dyno or a drag strip you wouldn't even know that...

Original headpipe was 2 1/4 except for around the starter, tailpipes about 1 7/8. Accurate limited's standard is 2 1/4 all the way through and fit very well. Aluminized pipe. Various types of mufflers can be had for various inlet and outlet sizes.

Dynomax Super Turbos - great sound, last a loooong time and dirt cheap. What's not to like? I spent a bunch on Flowmasters once, thinking they were better, what a disappointment...

IMHO - retorque the exhaust gaskets - when the engine warms up, the exhaust expands and takes up the tolerance. When it's cold, the exhaust flange hitting the head when the correct cylinder fires because it isn't torqued properly)

Many years ago I was whizzing down I-5 on business and there it was, I could see Accurate's operation from the Interstate, so I took the next exit and walked in. I had their exhaust on 2 Darts and was amazed how they fit right off the bat - no beating or banging. I talked to the woman at the...

I ran across a POR (as in POR-15) product many years ago and used it ever since. Factory Gray Manifold paint. Comes in a little can and you put it on with a brush. When you run the engine the paint melts into the manifold and all brush strokes disappear. The best part comes when the...

try Hedman Hedders

Here is always the question: What are you going to do with the car? Are you trying to be serious at the drag strip, are you going to drive it on the street 99% of the time? The lower the rpms, the smaller the difference between the two. If you are actually going to drive this on the street...

Just to clarify (since looking at it this morning) the original tail pipe ends and tips are directly under the frame, so if you move the springs under the frame they are right where the original exhaust location is...

So here are pics of my 70 Dart with Accurate Ltd. pipes. The washers at the hanger/insulator move the pipe in 3/8 of an inch. This picture is taken with the car on a lift, and the hangers rotate down and closer to the pipe when it is on the ground - make sure you install the hangers with the...

You are talking about the 3/4 inch relocation and not the 4 inch relocation right? If you move the springs in line with the frame, as opposed to up against the frame, you would be better off to take the end of the tailpipe over the spring and have it come out on the outside of the spring if you...

I have 2 1970 Darts with the spring relocation kit installed. I used the standard 2 1/4 inch pipe pieces from Accurate Limited (who do not, by the way have proper 70 Dart tips available) and the pipes fit fine, but I had to put 4-5 washers between the rear insulated hanger and the frame to get...

The conical washers are to spread the stress of the bolts on the relatively fragile cast iron manifolds. (how many small block manifolds have you seen with the "ears" busted off?) Use on all the studs and bolts where they can be used. Use bare bolts on a cast iron manifold at your peril!!!

so if the end of those pipes are 1 3/4 ID where they are swelled for the tips, I can only guess how small the actual tailpipe before the swell is - 1 5/8 or less???

the Accurate Liimited tailpipes are 2 1/4 unless you ask for something else. IMHO if you want something smaller it would be more straight forward to just stuff a rag up the tailpipe

use some kind of dynamat-like insulation and lose the drone....

Wow, I have never seen that before. The tip that is shown in your original posting looks like the tip used on 1970 340 Darts, which would make sense since 73s had the same shape of bumper/valance panel. Learn something new every day!

The original chrome tips fit INSIDE the tailpipe and had an I.D. of 1 5/8 - what engineer let that slide by??? Back in the day when nobody cared about originality we used to slip a 2 1/4 pipe over the original tips, mark it and then cut off the restrictive end of the original tip and then weld...

So here's some pics of an NOS 1970 Dart Swinger 340 tip. If you are looking for something that replicates the look the critical thing is that the box extend well beyond the bracket, which if installed with a factory type hanger (accurate has them) will be just before the edge of the valance. As...

The ones from Accurate are not like the originals in that the square box is much shorter in comparison to the originals. The ones that you would want are like the ones only made for 1970 Dart Swinger 340s. The deal is this, from 68-69 and after 1973 the back of the car had a bumper that went...
