I did a few years ago when I put the ceramic coated Doug’s on my 72’ Demon 340. At that time SS manifolds or headers were frowned upon because they seemed to crack at the welds. I went with the ceramic coated version and never looked back. My car is garaged and kept clean so they have not rusted...

Hi all, hoping to get some reviews/experience with this kit. I want to use it together with TTI 340 head pipes and oem hipo manifolds. Reason for mixing 2 brands is simply cost. Ordering complete from TTI isn't an option. Unreal shipping costs and budget. Summit only offers "header back"...

I failed to mention that a Magnum engine will require an electric fuel pump as it does not have the components to drive a mechanical fuel pump. This is a dealbreaker with some. A Magnum engine will be a little more work such as outfitting it with the LA timing cover so you can run the LA V belt...

340. Cars running a accurate exhaust OEM kit.

FWIW back in the late 80's I tried literally a dozen cams in a E58 360... Low compression, nothing special but I kept trying cams, manifolds, carbs & timing curves to get it running the best I could... The 2177 with an LD340 that had been modified to accept a Tquad was the final combo that I...

Hello All, As we all have access to dynamic compression calculators and gear mph graphs...I'm looking for feedback from individuals who run solid lift cams with oem exhaust manifolds. Gears are not an issue (plenty of sets). 904/727 available 26" tire. Building a sleeper for my Son. 72 dart...

...just fit, didn't leak, didn't hang down. And they also were worth 3/4 second in the quarter on a mostly stock 360, vs. the hi-po early 340 manifolds I had been running. Three-four years ago, I also put TTIs in my 65 Barracuda, 340 4-speed, manual steering, no A/C. I got them to fit, but I...

I'll probably stick with the Edelbrock 1406 that's on it now. Seems to do alright.

I have been told that the stock manifolds are free flowing and there would not be a huge power difference if upgraded to headers. Would like to hear from members who have replaced their stock manifolds and if they noticed an improvement.

FOR SALE: 1969 Dodge Dart GTS. 340/727. Real GTS with matching numbers engine block. Car was restored around 2005, and I have owned it since 2007. Car was decoded/verified by Galen Govier. Paint is Y2 Yellow basecoat/clearcoat done in 2005, still looks great as does the chrome, interior...

Thanks for your comment.

Very true. But we've all been known to resort to some ridiculous things when we have to. :lol: Even the factory 340 manifolds require a somewhat severe bend to them.

The cr and valves puts it more in line with the older 340, be nice to know the cam specs.

The engine was thoroughly gone through when it was rebuilt but I am not sure if it was sonic checked. It was rebuilt back in the early 2000's, reassembled and stored in a crate in the corner of the garage until about a 18 months ago when I dropped it back into the car. After storage, drained...

Hi all, not looking forward to this as I'll be doing this on my back, so looking for any advice you can offer. I bought the Summit 2.5" kit(Heart Throb) https://www.summitracing.com/parts/sum-680144. As well as TTI 340 headpipes. In our 67 cuda FB, console shift 340/904, 8 3/4 factory 340 hipo...

Maybe some guys can shed some insight on this build. I have a 1971 Dodge Demon 340 that I am building as a T/A package car. I want to add all the T/A options as if you could order it on the Demon/Duster too. I have most of the list accomplished but I cant find what shocks were used which brand...

How many of these “Other” intake manifolds do you see on cars and for sale. That alone should answer your question! Your interested in 1 of the 4 intakes below: RPM/RPM-AG Performer Stealth Action Plus Alternatives are; OEM 4bbl LD-340

I prefer the older 67 - 69, (possibly 70) style 318 manifolds over those heavier later sets... But the best exhaust manifolds for a 318 are the 68 - 70 340 manifolds... But you will have to use a 90° oil filter adapter for those...

That's why I have long advocated for the 360. It got a bad reputation due to being released at the beginning of the smog era and not having a performance option until 1974. I remember conversations in the early 1980s with people degrading the 360 as worthless. I knew they were mistaken...

Nope, too new. The 68-70 340 manifolds are the first choice and the 71-74 manifolds are next best. There are combinations of LA and Magnum manifolds that work well too. There are many threads here on FABO about all those choices. Yes, if the headers are in good shape I would probably leave them.

318 net hp is 150. Going from gross to net, they lost 80 hp (rated, not actual) with the same compression, carb, etc. as it had before. The 340 went from 275 supposedly gross to 240 net after losing two full points of CR, getting smaller exhaust (edit - smaller intake) valve and (at least...

...did a test on a crate 360 many years ago, comparing the HP and torque numbers using several different manifolds, then headers. The 340 manifolds added a surprisingly small power increase over the basic 318 manifolds. Headers added far more. The 340 manifolds added something under 10 HP, a...

A 327 2 barrel was rated at 235 horse. Huh! My 273-4 barrel was rated the same. According to the information below, the 318 did pretty good for itself against Chevy's 327. "The last iteration of the 327 appeared in 1969 with a two-barrel carburetor and a 9-to-1 compression ratio that...

been using 51515 filters with those 340 hp manifolds on 3 LA small blocks on 3 1970 Darts for 30 years... I think they work!

that out of a 69 340? my valiant ran 14.2's all day long with a stock 79 360 long block with a performer intake and 600 holley being choked down by 273 manifolds. 3.55 gear too..

Yep! The previous owner installed the absolute cheapest headers on the market. The flange literally drags the dirt road I live on, and going in reverse is absolutely out. I went to raise the front torsion adjusters, but the center link is already hitting the lower header tube, and of course the...

Don't go to too much trouble. The issue that I am having a problem with is the placement of those washers. My service manual says they only are to be installed on the studs on the #2 and #8 exhaust ports. There's actually a photo with arrows pointing to those studs. But it makes no mention of...
