 Re: custom manifold2 Wouldnt that make it a bit hard to tune with the different length runners? How come you made a custom manifold in the first place and not use a off the shelf item?
Points for being original though

Re: custom manifold2 That would be because it is for an oval port head and a single dcoe. Canon manifolds are just too hard to get.
Beattie your right though. It really needs to have the same length runners to get it running right. The long runners would make it like tunnel rams up high. Thumbs up

Re: custom manifold2 I think it'll run just fine with unequal length runners -- certainly manifolds with plenums have no problem. Of course again it is 'best' to have equal lengths.
That reminds me...one bore feeding two cylinders changes the sizing of the carburetor considerably...what is the effect on that now let me think
