Big Block Truck Headers/Exhaust manifolds wanted

[66plyValiant]

I recently removed a 400 B big block engine from a 1977 tradesman campervan to go into a 1977 dodge D-150.
It fits perfectly as far as mounts and pan go, but the passengers side manifold hits the frame rail; don't know about the drivers side yet as I had to remove the manifold to remove it from the van. any pictures or anything is a help

On my 78 D-150 440 powered truck I installed a set of the B-body 383/440 magnum manifolds... These are said to not fit, I found only 3 mods and they fit fine... Left side only needed a slight mod to the kick down linkage and a little massaging of the firewall... Right side I had to heat and bend up 90*a small section of the frame... You do see many truck frames that come from the factory with small sections of the frame bent like this... The stock truck manifolds flow like crap with only a 2" outlet and are prone to cracking...

I was hoping to use the van ones as it was a 2 1/2" outlet on both sides, but the passengers side is resting on the frame and I don't know what the drivers side is going to do

You will have to mock them up and see... On the pass side I had to add about 1/2 inch of clearance by bending the upper flange on the frame... Did it with the engine in the truck ..

I would much rather not bend the frame rail, truck is somewhat valuable; at least to me.

its long wheel base stepside with a custom tilt front end. not many trucks around here like it, quite a few short wheel bases but no long wheel base stepsides

I have an NOS pass side manifold, I'll have to get the number off of it but if I remember it was for late 70's thru mid 80's
$60.00+ shipping
PM here if you want it.

If you can't find one closer send me a pm. I'm pretty sure I still have a couple. I believe one set is off of a '76 truck. Shipping from here to you would be pretty expensive due to the weight, I would imagine.

Stock manifolds on my 78 were both center dumps, same manifold left and right ... Some class A motor homes have the same manifolds... I do have a pair of truck, center dump manifolds left if ya need em... Tweekin the frame rail was no big deal... ya could always bend it back...My truck was rare 1 of 74 built in 78... I traded it for a 67 Barracuda...

I have a center dump drivers manifold and it won't fit the drivers side; it seems the manifold needs to be closer to the block its also very close to my custom electrical pannel which has the quick disconnect for the tilt front end


the passengers side is rear dump and fits fine. I'll grab some pictures and post them

 

[66plyValiant]

heres what I have for the drivers side (left) and it won't even fit in let alone bolt on
