My bad, that is actually a Felpro1243, shown in pic, but the pen marks shown show where the 1213 340 ports were marked. I will edit above post.

I got mine used, from a member on the site for a good deal. My first thought when they were hitting after I dropped, the jack was your thread, and then I wonder if someone would want to trade for some 340 manifold?!?!? lol

I've been eyeing this cam but thinking maybe 108 centerline? Also maybe going solid. Expert I'm not. 340, 10 over KB pistons, 160 cranking pressure 10:1 Comp (I believe), Eddy heads, RPM intake, 750 ABS carb, Stock manifolds 2 1/2" Exhaust, 4 spd., 323 rear gear, 235/60/15 tire. Street car with...

Thanks, I got tired of messing with the Offy as I was trying to get 340 built. And get to Moparfest which i missed lol. So I pulled it off the 273 and shelved the setup for now. Once 340 is installed I'm hoping to put commando pistons in 273 and then take a stab at dq again. They just look so...

I bought same NOS dual quad thinking I could use on my 340 build(x heads)....not a chance lol. Like you said the outside of the flange vs the port, you could see daylight lol. So it went on 273 for a short stint lol. I love the looks of them. Intake gasket is Felpro 1243 273/318 size. Orange...

To my knowledge Offy never built a dual plane. The 360* is the designation for a single plane. IIRC all of their V8 intakes were marked 360*. I have one sitting on the top of my 360 in my work van. It has the 318 sized ports as the manifold I wanted was 340/360 specific. It ran fine with a Comp...

I have a set of 340 hypo manifolds $600. Thx

Just my opinion, if you don't want headers, it's not worth the extra 60 cubes to choke through exhaust manifolds. I would build the 340 to do what you want.

Hi Folks Running a 340 auto with an XE262 cam, 1969 HP manifolds and a factory TQ on a 1971 Demon (3.23 gears). Looking to purchase a 2 1/2 TTI exhaust and see that there is an X option and an H option for crossovers. I am looking for something with no drone on the highway, and not...

Fair but if you're after a nice street ride, they aren't a bad option. Given the choices later A bodies have I'd easily opt for headers of any kind, but with the premium on early stuff, off... I'm a cheap *** so... lol

You can find 72-74 340 / 360 A body manifolds at pretty reasonable prices and just order head pipes that fit the manifolds you use. They are not nearly as expensive as the 68-70. That is what I did on my 69 Cuda with a 360 / 727. I sawzalled the headers off. I ordered my exhaust from Waldron &...

What do the current plugs LOOK like? They'll tell you all you need to know.

I swear I bought a pair of repops last year $600 ish? to replace some older ones that I had welded a crack on the lt one and had to remove what ever that stupid back pressure pos that was rattling on the rt. And I’d like to put it out there for all those guys that say you can’t weld cast iron...

For me. Post count jumps from 187 to 191 A 1-5/8 header I am going to assume. Yea yea, 100%, don’t dig. Not worth the time. Sorry, did I say it’ll jump to 370 hp? Because you keep saying this. As if I said it. OEM rated it at 275. You just told me above it dyno’d 326.2 hp. Lets drop the .2...

Yeah, you didn't see problems like this with the stock large gear reduction starters Chrysler used. Like I said earlier, the only reason I'd go to a mini starter would be lack of space.

how have your exhaust manifold gaskets held up. any issues?

Tuning is the key. The Try Y's I put on my 73 340 didn't do much if at all. There were no 60' timers back then. It might have had more low rpm torque but not that I could measure at the track. I didn't change a thing including rejetting the carb or even resetting the timing. That being said...
