Stock Magnum 5.2/5.9 camshaft w/carb?

IF you choose the Edelbrock carb, it is IMO you will like the Thunder over the AFB. Seriously consider this.
On the Summit carb, I have had the Holley version before Summit picked it up. Worked well enough I suppose. I had the small spread bore version. IMO, I thought it lack luster.

I also suggest a 2-1/4 inch pipe, NOT a 2 inch pipe for your dual exhaust. The engine can use it.
Muffler wise it is hard to decide on on what will be a quite enough muffler for anybody since it is so very objective. Though a good sounding muffler that is quite at cruise with exhaust manifolds that I have personally used and would do so again in a heart beat flat was the Thrush Turbo mufflers. I used them @ 2-1/4 off exhaust manifolds on a 360 engine. Now do keep in mind that the car had Hwy. gears @ 2.76 and a 26 inch tire.

What does that mean? It means low RPM's at Hwy. speeds that also translates into an engine spinning easy and not jamming the exhaust note out. We all know it's quitter at cruise than wide open throttle and 90+ mph.

Is the Thunder's adjustable secondaries that much of an improvement to balance out the mix on the Magnum?

What Summit carb was that? The one I'm thinking of is essentially an Autolite 4100 (Holley-produced-for-Ford) modified to support Holley jets and internals; thus allowing for tunability without bowl gasket leak concerns (and I've had it with 4160's and the leaky 1920 single-barrel on my Valiant):

As for mufflers: Quiet like an Imperial is what I want. I used to have a pair of Lincolns with Ford's lousy smogged-up 400's and single exhausts, but both cars ran as silent as you could ask with nothing more than a basic turbo muffler with a resonator just before the tailpipe. Worked wonders to shut 'em up.

Exhaust is the factory 2" single right now, so anything is a step up. I'll still need an additional hanger bracket under the rear seat (not much of an issue). Stepping up to 2.25" hangers isn't a big deal though, as new ones are all over eBay.

Not sure what to do with my two spare 2" mufflers now that came with the car now. More expenses...yippee!
