I'm putting a 2001 5.2Liter in a 68 B'cuda. I would like to get a bigger manifold than the 318 2-bbl originals. The Ram manifolds won't fit without modification. How would these 1979 360 manifolds do? Thanks
I have a '69 Barracuda (318 w/302 casting heads) with a large port ram manifold on the passenger's side and I'm running the 340 on the driver's side...they fit perfect. I got tired of header leaks and scraping the asphalt so I got the mag manifold and the 340. I'm a machinist, since the mag manifold exhaust hole is not quite as big as the 340 I machined the manifold out so it would flow as close to the 340 as possible. I now sell the manifolds in pairs, one machined 360 Mag manifold (pass) and one 340 manifold. Check out the pics. Of course, some people prefer headers but it depends on how much street driving you plan on doing. Expensive headers will clear the ground better but cost quite a bit.
In the pics you will see the 360 mag manifold machined out to the same size as the 340 also pics showing the difference between a stock 318 manifold (what you show in your pics) and the magnum....BIG, BIG DIFFERENCE!!! Also pics of the 340 manifolds I sell. I only sell them in pairs. It made no sense to me to have a good strong street cruiser that was being choked down by the small stock manifolds. Last pic shows how and where the mag manifold exits under the car, it shoots straight out the back and clears everything with no problem. These manifolds have been selling like hot cakes, I only have two pairs left. Good Luck with your build.
