So I'm pretty much done and done with carbs. Guy at the speedshop recommends FAST all in one kit. I have a stock intake manifold and use a Delco HEI distributor. He says I may need to make some changes to both the manifold and the distributor to make it work. Who out there has made the swap? What problems will I run into.?Always get good advice on the board, looking forward to what I learn here!
