Ls1 Heads Edelbrock Heads Test

Ralph Kehlenbach of Kehl Tech Performance strapped the Edelbrock heads down to its Super Flow 300, which utilizes a slightly larger 4.00-inch bore and 1 7/8 exhaust pipe. When tested at 65 degrees with a wacky 29.95 barometric pressure due to an oncoming blizzard, the heads flowed 300.1 cfm on the intake and 210.3 on the exhaust at .600-inch lift. Ralph said the difference between Kehl Tech's numbers and Edelbrock's claims can easily be attributed to a difference in atmospheric conditions, or perhaps even the slightly different testing procedures.
