I know one has a vertical orientation and the other has a horizontal orientation, but do the bolt up to the same flange? Could I bolt a Dell to an IDA manifold?
Thanks

 

Dellorto is based on the DCOE(if memory serves me) not the IDA. IDA has larger body and different flange. for this reason most people use the IDA for the extra air flow. all have been used on all types of rotaries.
