NZ 68 R/T Wrote:Hi Richard
I've got a 68 R/T with a 440 and have been considering headers. People have told me that I will have clearance issues with P/S and then I read your post. Where would I source these HP manifolds? Thanks
Many of the Mopar parts suppliers sell either original used HP exhaust manifolds, or complete new reproduction HP exhaust manifold kits. It REALLY is important to shop around though, as there are MUCH better prices for these manifolds at some retailers than others as you can see below in just the three companies I've posted below. These HP manifolds are not all that big, but they are fairly heavy, so shipping costs to your location should be looked into carefully as well.
Once again, if anybody is building a full fledged race car, then run a good set of headers, but for anybody else who is driving their cars on the street most of the time with occasional trips to the drag strip, or runs their cars in the street legal classes like I did with my Coronet, then run the HP manifolds. They will fit without any issues no matter what options your car may have and they won't cause any clearance issues with starters, front suspension parts, steering parts, or 4 speed, or automatic transmission linkage. My '66 Coronet 500 has power steering, power brakes, a full manual automatic transmission and is also a factory a/c car and my HP manifolds have no issues with any of those options. (I removed all of the factory a/c equipment for drag racing, but it was all in place when I installed the HP manifolds on the 383 and then the 400 engines I had in the car before I did the swap to my current 440)
