340/mag360 exhaust manifolds
OK, here we go.....From Corpus Christi Texas. I have quite a few 340 and 360 magnum manifolds but before I start listing there is some information you need before you make a wise decision. I get these manifolds, get them sand blasted, checked for cracks, machine some of them (will explain later), then put two good coats of HIGH HEAT PAINT on them. Then I put them under a heat lamp to cycle the paint through a few heat cycles. So these manifolds are ready to bolt on and GO!!! I will have to make a few different posts to get all the pics. But we'll start with the Mag 360 manifolds. Certain years are the best and that's what I have. I match these 360 Mag passenger manifolds with a 340 driver's manifold. I do this because, although I could sell a matching set of 340 manifolds, you get better flow (horsepower) from the "machined" mag 360 and driver 340 manifold set-up
(AND IT IS CHEAPER!!!). BESIDES...a pair of 340 manifolds cost way more than the 340/360 sets I sell. If you look at the pics you'll see what I am talking about. The 340 driver's manifold comes with a 2 1/4 (plus) exhaust hole (no wonder they made so much power!!). The Mag 360 manifolds come with a 2 1/8" exhaust hole. But I take the 360 Mag manifold and machine it out to 2 1/4" so that it more closely matches the 340 driver's. Now, in the pics you will also see some 340 passenger manifolds, these have a small 1 7/8" exhaust hole. I'm not sure why the 340 passenger manifolds are designed that way but that's the way (maybe be a engine bay "space" problem) it is. So......you have a choice, an expensive set of 340 manifolds with mis-matched exhaust holes OR a set of matched 340/360 Mag manifolds that have exhaust holes much closer to the same size. The 3418623 340 and the 3418621 340 (see pics) are both listed as 340 manifolds but the have small exhaust holes.
I sell a set of 340 driver's manifold with a matching (machined) 360 magnum manifold for $290 plus shipping (BLASTED, PAINTED and READY TO BOLT ONTO YOUR MOPAR). I run these on my '69 Barracuda, 318, P/S, P/B, A/C and they fit perfect!!! The 360 Magnum manifold exits at the rear where there is PLENTY of room for hooking up your exhaust (I have pics) and minimizes sharp bends in your exhaust flow.
I have a limited number of these 340/360 sets so the
first person who sends the cash will get a set until I manage to get and machine more.
These sets will work on 318 or 360 engines for those like me WHO DON'T LIKE HEADERS but do like power!!>
PS - you could scrounge around the junk yards and find a 360 manifold (hopefully you'll get the correct one) and you could machine them and have them blasted and painted but
then you'll still have to find a 340 driver's manifold AND IT WON'T BE CHEAP!!! By the time your done you would have spend well over $300 and lost precious time.
