man it seems no one does research on this
. the offey intake was bilt for spliting primarys and secondarys through out rpm band it is suspost to give u a cooler charge of gasoleen and they flowed a little better now in my experience i have had a 22 R, 20 R,and the 21 RU i have ben running on propane for three weeks now and i far as i can tell it wont help much to put on a offey with propaine it dont matter popane will run with a stock intake just fine. and i just dont c the point of putting an offey on a propane it wouldent be able to tell the diffenence
and i am talking about a offey dual plane you can by a c series for a weber but it does not have dual ports for your primarys and secondarys
