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...

*And performer RPM

trying to buy some parts from this guy, and dont know fair price to offer him, for him and me, maybe you guys could give me a price to go by ? thanks 340 motors 1968-1972 complete manifold to pan ? sb hp manifolds ? 83/4 pigs [center sections] posie ? fresh 360 short block ? 4 speed trans a...

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...

I can tell you that having a bone stock 72 340 4spd 323 peg leg Demon ( had factory T-quad), only had a set of Hooker super comps on it it ran great for a stocker..lol. when I went back to manifolds, it lost a lot of quick rpms, lost the torquey feel and generally felt like a dog . Headers...

If it's gonna be stock and you're ok with leaving 20-40 ft lbs in the table, pretty much everywhere across the power range, then any old stock manifolds will do. Yeah the 340 mans probably make a bit more than the others. The cheap hedman headers are total garbage. The cheap summit branded...

I have for sale the full exhaust off of my 340 demon. The passenger side manifold is dated 4-15-71, 3418623. The heat riser and flapper is gone. Drivers side manifold #2863553 I sand blasted the manifolds and sealed them with HVT, the HVT could easily be removed if you prefer it raw (pause)...

Totally agree. If you look at Chev's performance 302/327/350 all built pretty much with the same specs, they made basically the same power curves just at different rpms. And if you geared each engine to be operating in there powerband at any given speed each would be putting down similar hp and...

I sold my early 340 manifolds for enough to buy a set of TTI's.

I have a very nice complete six-pack setup for sale. The carbs have been rebuilt, including new diaphragms. The fuel lines and linkage are complete. I have a spring kit for the vacuum pods. I did save all the old components for the carbs that were replaced. This includes the air cleaner...

the melling MTD cam is going to trade torque all the way across the board for HP at the top. it's still a good cam, that's similar to the factory 340 piece. personally i'd choose the MP cam. the split pattern will work favorably with the exhaust manifolds and the narrow 110 grind will keep the...

In post #7, the top pic is the same style 318 manifolds as your original pics. The second set in post 7 are B,C,E body small block manifolds. The passenger side will work in an A body, but the drivers side won't. What would work the best are a pair of 72 and up 340/360 exhaust manifolds. Sorry I...

i have the same car 68 gts 383 4 speed LL1 color and mine has a nice rumble to it with stock manifolds, yes i have flow master mufflers but it sounds great .

correct, for both the 5.2 and 5.9, which is also the same outlet size as the passenger-side 340 center dump manifold. I just checked and the 318 is 1-3/4" outlet...but a 318 is not a huge engine.... 318 above, 340 below - Still tho...I really wonder how much that tiny difference will...

Too bad I'm in SC...I got a 727 with cheetah Rev shift pattern valve body ...with deep alum pan with cooling fins...has converter around 3000 stall...looking for 68-70 hi-po 340 manifolds
