340 intake I am not familiar with

They are basically a copy of the early 340 manifolds. They perform really well. Next step up is a Weiand Stealth or RPM.
I have a Weiand on this motor . It is a stock 318 with a 600 carter. It works great . instant throttle responce. The motor is a 1973 34K 318. single point.

I painted it orange to look more original. The ports were much larger than the 318 heads but it doesn't seem to affect the performance at all .

No coil bosses or choke well. I had to use a manual choke.

Thanks for the info. I sort of like the mopar intake. It lets you use all the original parts on it. I wish I would have used it now instead of the Weiand due to the choke well
