Search results for query: 340 manifolds

If you search here, all that has been discussed. All the numbers and any modifications to do. The only reason for the Jeep manifolds is because the right manifold exit is close to 2 1/2" . 67-70 340 manifolds aren't a issue (if I have my dates right)

...i wouldn't say that headers would be "necessary" for your application and intended power goals, but i would certainly recommend it, or 340 manifolds if you've got those on the shelf. will shorties be better than manifolds, sure but not by a wide margin. it's up to you to decide if that...

Most people can't envision past what the factory deemed performance engines anyways, bet if the 318 came built with high CR 340 specs there would be less debates on here. I bet the 340 have less love, but that has little effect on it's capability.

People go with 318s cause they cheap or free...they never were powerhouses unless you are easily impressed. Will they sound good in a Scamp? yes will the Scamp do a "burnout" yes will the Scamp do a 13 sec quarter mile with a stock 318 ? no would it with a stock 340? probably...that's why I look...

Being that the 360 is going to be stock or close as to stock as possible w/exhaust manifolds and only a rpm intake and whatever carb works for the task, the MP cam will probably reduce very similar power to the 340. I’d call it a 300 hp engine because of the intake and better exhaust pipes and...

4~7s is market rate and a good deal for 340 manifolds. go price out a set of headers and even some cheapies are gonna run you 3~4 easy money, then tack on coating which even the absolute cheapest job is gonna be *pulls number out of thin air* let's say 3 hundy. or you buy two cans of VHT and...

I have TTI's on my 65, doesn't look to me like the master cylinder is any closer to the headers than it was to the 340 manifolds I used to run. I did fabricate new brake lines from the m/c down to the combination valve, which I had to move to the rear to get it out of the way of the headers.

ha ha. rrriiiiigggghhhhttttt. and you wouldn't use 340 manifolds why? please explain your position on this so that we may all roundly ridicule this statement. or is this one of those things where you just got back from a peyote retreat in joshua tree and you're still hearing colors and...

I was told the gaskets will not hold up when using 273 manifolds on a 340/360 head but if there was never a problem then i will put 273 manifolds on my 360 build in my 65 barracuda

That was average a few years ago. Nice pairs are a easy $600+. Look at what they do and how easily they do it. If you don't want to screw with headers on a mild street engine, they are a good alternative.

Depends on the year of the 340; or more precisely, the year of the heads. If they are later heads with the large exhaust port pads, there will be interference. 1965 MOPAR, 273 Exhaust Maifolds

I used to own a 74 Duster with a stock 318 that I put el cheapo headers on. I eventually destroyed the headers on a road trip and had to saw them off with a hacksaw. I replaced them with a set of 340 A body manifolds from a 72 Duster 340 and noticed absolutely ZERO difference in performance...

Body, patina galore. I have replaced floors, and added frame connectors from us car tool. Included at ask is a rust free set of quaterpanels. Suspension, ffi everything ( front and rear sway bars, tie rods, upper control arms), borgeson fast ratio power steering, new 6 leaf hd springs, new...

I have a pair off a 69 Barracuda 340. They are manifold to muffler. Might have the matching tailpipes and factory tips. Have the manifolds too. They are circa 1969, lol. But have been hanging in the shed since around 84 when I took them off the car. I interested PM me

Probably true, but my 340's power noticeably improved just swapping from OEM to Edelbrock heads on my 340, while keeping the stock exhaust manifolds. Of course, it runs better now that it has headers.

Only in So Cal could that be a driver, around here you'd need a dust buster every hour to keep the engine that clean, even in the shop.

1-3 is correct. With what I'm looking at doing, I think that I'll stay with the factory exhaust manifolds, maybe clean up the opening, run a good, free flowing exhaust system, dual pattern cam. Open air cleaner housing or equivalent. Edelbrock avs2 carburetor, weiand intake with 318 size ports...

1971 340.....XE262 cam with OE Intake and exhaust manifolds and OEM Thermoquad. Experimenting with ported vs non ported vacuum advance.

I got 73 340 manifold 2 1/4 and 96 Dakota passenger with the 2 1/8 outlet with head pipes that will fit any a body 67-72 $500

I could never figure out why. I put a set of Mickey Thompson Try Y's on my 73 Challenger. 340 car. I didn't do any carb tuning after the install but I slowed down a few hundredths. It went faster with stock manifolds and full exhaust.

I have been going through and trying to read as much as I can. Sometimes it’s gets a bit overwhelming with the headers vs manifold debate. Sometimes I just may not be searching in the right threads either I am sure.

The goal is to go quicker than him, 10.2’s at least that’s how quick he is right now. Stock valve cover, ported x’s, exhaust manifolds and tweaked stock 340 intake. AVS for me. He gets a thermoquad with his Duster. :(:(:(

I don't believe I have seen any flow results. Thinking about that, how would you flow them? All the ports at once would be the most accurate.

I hadn't considered that...that's kind of a good option, especially since the car at present has NO exhaust system, just craptastic headers and glass packs that dump under the seat area.

Way back when i was 17, a guy my brother was friends with gave me a 340 Challenger needed a transmission. Had I think Blackjack as had slip tube on driver side header no fancy spark plug wires or covers used I never burnt one ever. Changed them out for some Headman AK5000 since I dressed engine...
