For all you guys running HP manifolds on their 340, wanted to know which of two filters to buy. The HP manifold and head pipe clearance is why I'm asking this question. Do not have head pipes to help me make the decision. May be a stupid question but here goes. 1968 340 application states...

Wow those look amazing! And far less hassle. The only thing I might have a little concern with is loss in horse power. I am building a nitrous motor. I went with a scat rotating assembly, 3.58" stroke crank all forged steal rods and crank , and forged aluminum "icon" pistons. I'm building this...

This was a pretty good episode. Nick took a stock 1972 340 and did a mild build on it. Stock was 8.5:1 compression and now it has 9.8:1. Some mild porting of the stock heads and intake valves are now 2.02 vs the stock 1.88. Stock cast iron intake, stock thermoquad carburetor. Unfortunately the...

Looked like 340 manifolds

Yes, that's the problem at the bottom of the port with stock replacement magnum heads. The 340 manifolds are a large LA port and the magnums are a small port head. I made some 16 gauge block off plates like Dion R made and they leak slightly around both sides of the plate. it's not much...

Well, I don’t know about that, I’m just putting it out there in case somebody wants them. No issues with the car, took it to HP Engines and had it stroked and got these back from Hollis.

All 340/360 4 barrel manifolds are very good. Take it to someone who can weld cast iron and get an estimate first, then you can make a good decision. For me that would probably be too much, but I have had exhaust manifolds welded with at least 40 years of service and still holding up fine.

Price any 340 part or car. Last pair of 340 exhaust manifolds I saw for sale were like $400

Do you still need pictures? Cause my '69 340 has the manifolds bolted to it with reproduction hardware. But its under a table with blankets and plastic piled on it but I can get pictures if they still needed.

The hp difference between 360 vs 340 manifolds to me aren't worth the swap. But like everything it's up to the individual.

340 manifolds aren't exactly a clean fit in the early A body either, although they take less work than the Magnum manifolds. And then there's the port mismatch/sealing issues and outlet to head interference to deal with. And the cost. Magnum Heads On 340 Easiest (and since you're admittedly...

...dart with a 360 and power steering. Currently I have the 273/318 2780945 exhaust manifolds on it. Are the expensive 2863549/2863553 340 manifolds my only option? I do not want headers. Will those 68-70 340 headers work with power steering? Sorry, I know there are a few threads on here...

They were reproducing 340 manifolds a while back but thought I read repops not being made anymore? If so thats gonna drive the price up.

This will probably raise some eyebrows. If two 1973 duster's were the same weight, had the same size tires and tire pressure, both had 3.23 gears, a 904 transmission with a stock rebuild, stock stall speed converter, one has a 340 the other a 360 but they both are rebuilt to the 340...

My big fingers, I meant to say 340's

...for the A body small block when they won't fit. I think that it's been said that the right side fits but not the left and for that the 340 manifolds have been suggested but they are hard to find. What about manifolds from the volare / Aspen that had the 360 or a diplomat,etc. Was there a...

i got lucky and found a really nice pair a Carlisle the other year. I liked the price, the quaility but the fitment mmm For what they cost i think they should fit better Thats just me

My plan would be a stroker with manifolds 150 shot and 3.23s and hope to get 11.40s prolly cant do it with 3.23s

I dunno that just doesn’t look safe, that motor would have to be chained down because if it shifts up it’s going to push on the steering shaft. Wish there was some better picture cause it looks like it’s resting on the manifold……….

Yes.

Yeah I've seen Gary Povlovich articles about them. The 4" arm for the 340 is a direct drop in. They can be made into stump pullers.

I had a simple 2 1/4" dual exhaust with the 273 and factory manifolds in our 67 cuda. Sounded awesome. Recently installed a 340, and went with 2 1/2" TTI head pipes and 2 1/2" Summit kit from headpipes back. Sounds great, deeper tone than previous setup. The 2 1/2" is tight, I wouldnt recommend...

I had 340 manifolds on my on my mild magnum build, went with the cheap summit headers, and remflex gaskets thread locker on bolts. I’ll never go back to manifolds the amount of torque I gained and h.p was worth it!

72-74 340-360 A body manifolds are relatively easy to find, and are a lot cheaper than the 68-70 versions.

someone was repoping the 340 manifilds.. originals were cheaper..

Yeah shipping 340 exhaust manifolds both ways would be crazy $$ + insurance.

He didn't but they were the early 68-71 340 manifolds.

TTI shorties. It didn't come with any exhaust so I figured if I was going to pay a hefty chunk of change for exhaust I'll skip on the collector (over)priced OEM 340 manifolds and pay for the HP bump instead.

They are not that hard to find if you have about $600-900 in your wallet. They even make them new now. If you don’t want to the spend that much, the 72-74 a body 340 360 manifolds are a lot cheaper. That is what I have on my 69 Cuda.

...experience, I replaced the stock manifolds on my old otherwise stock 73 Duster 340 with cheap BlackJack headers, and replaced the 68-70 340 manifolds on the mildly modified 340 in my 65 Barracuda and the mildly modified 360 in my 67 Barracuda coupe with TTI. In all cases, the power...
