Thanks Bob.
Do you know if the flange on the 429/460 is the same (size and bolt spacing) as the 351C & M? I already looked at all the matching numbers for the 351C, 351M and 400M and they are all pretty much the same and interchangeable. I'm not worried about interference with anything, I run an MSD distributor and if the funky hose set-up that was on there works (it did, just looked like crap)

, I won't have any problem with the 90 degree neck.
Thanks,
Jim
