The 6 pack i have bought was supplied by a well known Mopar supplier in the states and has been built for a 318/340 and has been jetted with that in mind...it also has a progressive linkage so too much air is not an issue...but time will tell I suppose... I think the best way forward is to get some heads from Edelbrock for a 360. That should take care of the larger valve issues you think i will have..... Port matching is a good idea and will be easier with ali heads and inlet....so thats the heads....

now what about the exhaust...as you can see by the picture I added earlier...they are cones...I wanted to change them to 4 pipes each side...kind of like zoomies but i think they need some kind of baffel in them...back pressure or lack of it may be a problem... any suggestions on that???
