He did mention the possibility of an internal balance with lighter rods and pistons, along with some mallory metal. I think the Scat I-beam SBM rods are about 100 grams lighter than the stock ones. Not really wanting to spend the extra money on this build though, especially for "special"...

Yeah, I agree. I would bet my house that Mopar Performance didn't sponsor the episode on the back of their M1 dual plane, and we already know the Edelbrock Air Gap is pretty much the gold standard for dual plane small block manifolds anyway. The only thing we really learned in that episode is...

Any chance of seeing how your pipes fit under the car? I'm about to do the same thing.

Hey Wes. Having both scenarios played out in my own cars, both in the same car, I’ll fall you what the LA lacks and you can take it from there. In my experience…. The LA lacks compression. Being a ‘79, in the heart of the crap power years due to emissions, it will only recover so much. This is...

If anyone is considering doing magnum manifolds on your car while your at the junkyard pulling the manifolds snag the downpipe too. I was having some clearance issues on the drivers side causing issues with the kickdown linkage. So I got the bright idea of using the downpipe off my 2001 ram...

Small ports can be good for port velocity. Obviously you watch DV videos. Take note of his mention in Ep80 of down the road installing inexpensive and lighyer Chev LS valves. Spring installed height could be an issue, but the LS springs, retainers and keepers can be used, even from a wrecker to...

These came off of a 93 W-250 with 5.9/360. As you can see they have the desirable outlets. Will work on trucks, have seen people use at least the passenger side on A-Body cars. Driver side is crusty, but, no cracks on either one. Asking $100.00 plus the ride. PM me here. Thanks, FABO!!

There's a couple reasons to this...But being that you also compared the engine with a carburetor to itself with injection... let's go there. The fuel injected 5.9 is managed by a computer with mostly a fixed tune. Has anyone here flowed/determined what the kegger flows? I hear as cast it is...

I think the old 300hp crate motor exhaust test is worthless. The cam in the stock Magnum 5.9 (which is the same in the 300hp crate motor) is so small that there were only minor differences in power between them all. But the cam was already limiting the motor so any difference the exhaust made...

Something wrong there! Best mileage V8 I had was a ‘79-360/904/2.76 in a Dodge Magnum sporting 235/60/15’s on all 4 corners. I gave the engine dual exhaust off of the exhaust manifolds @ 2-1/4 w/an H pipe, a factory 4bbl w/a 600 AFB and a vacuum advance distributor from the junk yard off a...

My experience as well. Replace the kegger with a carb intake and normal distributor and the Magnums rocket to life.

I've looked at these a few times due to the price but have also heard these manifolds fit and perform poorly. Are you happy with how it fits and runs on your engine? I have ran a weiand action plus and the std edelbrock performer on mild motors and like the weiand better.

I'm running a BPE 408 so the RPM Airgap is a bit special with the use of the magnum style attaching bolts. Can't just swap manifolds, unfortunately.

I would contact the manufacturer and show them what's up. With that design you aren't the only one with the issue. Possibly they caught the issue and made a production change to correct it. You could have bought a early manifold.

I'll get back with you

Tuning is important but especially if it's a carb'd application, air speed and booster signal at lower RPMs are crucial. They are directly related to how responsive an engine is under light throttle. Also when larger amounts of valve overlap come into play the tuning of the exhaust can make a...

I need to have my magnum large port iron ex manifolds thinned for my oddball swap. the center flange on the center ports are 1/2" thick. How much can I have safely milled? Thank you for your time. RR

IDK if that was a mention to leave tips and comments on YouTube but I’ll say the Magnum engine is as you probably know 245hp as it sits so a mild cam will help a little there. If you can get dual exhaust up the manifolds, I personally would go with a 2-1/2 dual exhaust. That would be very good...

I think I see a manual steering gear. If you are keeping that you could try Dakota/Ram/Jeep "Magnum" manifolds. Even the "small" outlet versions should flow better than stock 273/318/360 manifolds. ...and they sound good, too.

I'm definitely interested in what a properly built and blueprinted engine will do in terms of power. I'd also like to see it done in stages. Start with the basic engine, 2bl, manifold, stock cam etc. Then step it up incrementally and measure the effects. Richard Holdener does a lot of this kind...

I had 68 good manifolds on my manual steering 65 and didn't have a fitment issue. I bought it like this so maybe the manifold was ground on in one close area but I don't remember. Power steering no way. Did you try magnum logs? They dump high away from steering box. May have to grind a tad for...

That's actually a pretty good gap- about what I have with a Magnum manifold. I've seen them a lot closer with "ribbed" manifolds, to the point where people have hammered the fenderwell for clearance. You've got room for engine movement, so I think you're good. You'll never be able to easily...

MPH you showed would probably get you 97 mph in the 1/4 and a low 14. Your 10.65 would probably be a lower 9 in the 1/8 with traction.

Iron manifolds of one of the jeeps are supposed to be good? The magnum pilot bearings will work but you may need to trim the input shaft length a touch, or just rough drill the back end of the crank for clearance and use the magnum pilot.

Think that is the numbers on my intake. I'm sure a cam change , headers, aluminum intake and a 650 would wake it up a lot..probably get 50 to 75 hp gains

How much do you want to keep running a slant-6? The 225 is inherently inefficient by design with the super-long stroke and heavy rotating assembly. If I was to ever intentionally own a slant it would be the 170 variant. I think that would be the best bang-for-buck move in search for MPG and...

...for the big ones that I know of are 53006619 and 53006618. I believe that they were produced for 1992-1993 only. There may be other magnum manifolds that have 2 1/8, but unless mistaken these 53010187 and 53010186 are identical in outside appearance, but have a 1 7/8 inside diameter on the...

I know guys who ran that in 340's with squeeze, & like YY1 I ran the B version in a 383 with the stk. '66 9.2:1 in My case, no power brakes when it's chilly out until it warms up a bit. I ran a 4-gear, no way I would run anything less than a 3,500stall with that squeeze, & I'm talking 383... I...

either edelbrock or knockoff airgap, good thing about the knockoff it bolts on both LA and Magnum.
