That's a damn good start

...and tube if your 360 doesn't already have them. Exhaust is a cluster f*** on 360 early As- if you have manual steering, 340 ($$) and Magnum manifolds can be made to work, with some column modifications, but that will eliminate the ability to retain your column shift linkage, if you want to...

...not the rest of the exhaust. There are options, including 340 manifolds (very expensive these days), Spitfire headers or OEM Magnum manifolds. All this has been discussed many times, so I won't try to go in depth here. At this point, if you're keeping the 273 manifolds, I agree with those...

Thinking about using 360 magnum manifolds on a la360 & a set of j heads. Anything to consider besides the trans dipstick?

Do you have power steering? If not, I'd consider magnum manifolds. Almost as good as headers and can often be found locally for under $100.

...inch narrower per side on the early A vs the 67 and up. I'd probably never buy one again. That said it's a fun car for sure. The magnum manifolds that are the best ones are very comparable to the early 340 manifold with a huge opening (2.125) opening and can easily be opened up to 2.25...

Best possible bang for the buck would be to pull the 273 and install a junkyard magnum 5.9, with one of the eBay air gap manifolds and a set of summit headers.

Ran 12.20’s and worked it down to 11.80’s with a 410 using New Zealand EQ heads (w/1.92” intakes, not much for any porting other than guide boss tapering) using an Isky 280 Mega hyd w/1.6 rr, and a set of Dougs headers and 4.10 rear. Certainly you could get those iron heads to flow as well as...

I'd get rid of the "300hp" goal, 1st I would decide what gear and stall l'm willing/gonna be running 2nd headers or manifolds 3rd heads stock or mods to the heads or different heads. Better heads need less cam to get there, bet a stock 5.2 magnum has 90% of your power goal unlike an LA's 60%...

...just saying this test can't be used to show it is so. None of this helps the OP though. That test doesn't say anything about the Magnum manifolds and how they compare so it's not worth polluting this thread with beyond what has already been said. I can add that Holdener did a test with the...

Pair 340-360 Exhaust Manifolds 2 1/4 Outlet. With downpipes Removed last week from my 67 Barracuda w/360 $350 plus shipping PayPal accepted Shipping from Boise Idaho 83709 Excellent shape, excellent fit, no rust. Ceramic coated but has flaked in the hot spots Driver side: 3614368-2 (72-74...

Well I have the engine figured out... Reminder...this is a budget build...you have no idea! Bought a used 318 from an un named member here whom I have known for many years. Didn't spin over when I dragged it home but a little Earl down the cylinders got her freed up. $100 well spent. All...

Depends on the amount of interference you have, which can vary due to manufacturing tolerances and core shift in the head casting... the exhaust manifolds aren't really all that thick, and like I said the heads have a coolant passage right below the surface in that area. Test fit it, and...

Depends how your car is optioned. Power steering or column shift pretty much require use of the factory early A driver's side manifold (but will require grinding or an exhaust spacer to be used on later model heads). Manual steering and floor shift/pushbutton shift, you can fit the late A...

Although it does sound like it's running rich, I wouldn't do any tuning until the engine is completely broken in and 150 miles ain't it. Give it a little more time and then tune it.

Just curious. Will the magnum 318 exhaust manifolds fit in the earlier A bodies? Seems like that approach hasn't been mentioned..

...from the "Magnum" series engines do flow well. Not nearly as well as headers but still better than standard 318 units. The 1992-1993 Magnum manifolds had a 2 1/4" outlet. The right side clears an A body. I've used them. They exit over and behind the oil filter. The right side is an excellent...

i would love to see that same test with a 150 and 200 shot of juice see how much manifolds would make withe nitrous

UPDATE on the Inake Manifolds Mopar Small Block: The Three Magnum Intake manifolds were sold locally. Currently have the Red LA single plane intake in negotiations with: First in line- Dartwizer, @nd in line '68Cuda416. Posted new images-Let me know if more is needed. Thanks for you patience.

in a mild application shorties offer nothing when compared to 340 manifolds. long tubes with collectors will pick up hp & torque across the band and while the gain is not tremendous that little bump of 10% or so can convert into drivability and throttle response. with more aggressive cam...

You can do this with bolts but it's easier with studs. Arp studs that you would use for say... a Pontiac oil pan application 'hint hint'. You will want to use a cork gasket if stamp Steel and a composite gasket or even steel impregnated viton like a magnum... what you do is you put a little...

If I was to run a real cam one with a good amount of overlap to me long tube headers are mandatory to work with the overlap. With cams with a moderate or lesser amount of overlap I highly doubt there's a huge difference between manifolds but guess we won't know until someone does a test. But...

Correct! Correct! Holley first. Correct on both. The altered bypass was modeled after the Magnum set up. Why? I have no idea! Stupid IMO. Correct! Very close copy! I agree! They went to war with Edelbrock over some issue I can’t remember. But….. Holley got really pissed off at Vic and...

lol The first engine I put in my 67 fastback was a 68 383 magnum with hp manifolds, with matching convertor and torqueflite. that combo and a 4.57 sure grip was unbeatable by any stock a-body 340. lol a couple years later the 383 got 12.1 comp , ported 906, 557 purple, street dominator / Carter...

iirc, there was no dakota RT in the 92/93 years that these manifolds were produced. I just know them by part numbers, but they do have tue 2 1/8

I had a 1988 Chrysler Fifth Avenue, roller-cam 318 that was bone stock when I got it and very well maintained. I got rid of the Spark Control computer and converted to conventional electronic distributor and an old MSD box I got for free from a friend. Put on a Performer intake and Thermoquad...

I told him I can’t get into flowing them right now but for whatever good it would do I could look it over. After hearing what he paid for them I sure wish he would have called me first. It is for a magnum combo with I guess a hydraulic roller cam setup. He supposedly bought them from someone...

Well thanks to a fellow FABO member @416stroker it's obvious now why I couldn't get it to seal. It's not a simple issue of my methods being wrong because like I said I've swapped intake manifolds on small blocks at least 10 times and only ever had a sealing issue on this engine. It turns out...

I ran into the same problem with 340/magnum exhaust manifolds. Over many years it became too much work for too little money. I really enjoyed while it lasted!!!
