[font size=1" color="#FF0000]LAST EDITED ON May-05-01 AT 02:57 PM (CST)[/font][p]I am an automotive machinist by trade, and I have done a little research with the help of Engine Performance Wharehouse in Denver, and they suggest NOT to put flat tops in the TBI engine. With the size of combustion chamber of the head, the compression ratio and the computer will not get along. Now the race boys are using that TBI engine with flat tops, BUT, they are using carbs and no computer. Hope this helps.
