82 mirada 360 magnum exhaust headers?

[Mikes5thAve]

They didn’t note anything about clearance anywhere I read, just the over all flow rates. Apparently the ‘92-‘93 drivers side magnum manifold flows better than the 340HP drivers side manifold does.

But sure, could be a clearance issue, I don’t know anyone running them on their car to know for certain.

Here's a fitment issue link.

340 MANIFOLD VS MAGNUM MANIFOLD ?

I am thinking about putting a 5.9 magnum where my 318 is.It's in a duster.Will the exhaust pipe fit the magnum manifolds or will i have to get new exhaust?

There are others that claim on b bodies the column is in the way. Most of what I've read is those years flow the same or better then 340.

I have a car with them on it but I didn't install them.

Cool. This is what I had been looking at;

Whats the best flowing 360 exhaust manifold?

I wonder what the difference in flow really is. Is it really worth going after a 340 one for just the one side? And if you're getting into the power where it really makes a difference are you better off going to headers of some sort?

Anyone running these manifolds?

Guy a couple hours from me is selling a pair of small block exhaust manifolds. Not sure they will fit an A body though and wondering if anyone has tried. What little I could find, it doesn't look like an easy fit. Casting numbers 53006618 (driver side) and 53006619 (passenger side). They look...

maybe a set of block huggers. then no more 90 degree oil filter adapter

It’s got to be marginal. I was doing a little more reading and the drivers side magnum exhaust manifold definitely seems to be an issue on most Mopar cars. I got caught up on just, what is the “best” not the best for our cars, lol

yea. I lucked out, my Fifth Ave had the adapter all ready. People ask $150+ for them now and honestly for the money, a relocation kit would be better bang for the buck.
Shortys would look real nice under the hood, could have a nice exhaust made up too, look and sound real sharp; but you’ll spend the same on shortys as you would long tubes and with the long tubes, you get more HP and torque for your buck when you press on the gas pedal, lol
That all said, id leave the manifolds you got and get a nice flowing, sounding exhaust system made up; unless you got someone to lend a hand, then just go full tilt boogy and get some long tubes one there and let her eat.
