I’ve been unable to find anything about using one of your 273/318 Mopar dual quad intake manifolds on a 360 Mopar in your Q&A forums.
Could you please advise if your 273/318 low rise dual quad #5615 manifold can be used on a Mopar 360 without any modifications? And if not, can they be modified through porting, or some other machining process, in order for them to be used on a Mopar 360? Since the external dimensions of the 273, 318, 340, and 360 Mopar blocks are virtually the same, perhaps the port sizing of 273/318 cylinder heads is the difference?
If the port sizing is the difference, is there any reason the ports on the #5615 manifold could not be enlarged? Please note that I do have access to a very capable machine shop. If so, can you also please advise your current lead time on the 5615?
Many Thanks in anticipation!
There should be no need for any port work for a street car. You’ll need the 360 gasket but you should be able to just bolt and go.
We do not currently have any in stock and none scheduled for production. We need to see some increased interest in this product or a group buy before it would be feasible for us to begin production on it. You may be able to find one at one of our distributors or used on ebay.
