I just spoke w/Mike Yoder @ Kansas Kustoms-Seems like a real nice guy. He splits stock cast iron manifolds into duals, keeping the intake fuel heater intact. My question is a follows:

In a '54 GMC with a chevy 235 (appx '55-'57) would I have better clearance running the second pipe behind or in front of the existing pipe? Mike can make the new manifolds either way. Also, would you guys run both pipes to the same side?, out the rear or beneath the running board?

Any input would be greatly appreciated.
