Speedmaster Small block porting tips and results Part 1

Are the points you are talk'n about causing turbulence or are you shooting for volume?


Let’s take a step back for a second. Brett Miller an East Coast Head porter just did a small block Mopar Super Stock Edelbrock post on his Facebook group. Their is one legal Head from Edelbrock for this class and can be seen on Summits website. Now you can take that head and modify it but it still has to come in with an under 170 cc runner. His welding buddy added several layers of weld on the floor of the runner so he could raise the port and move the rocker and pushrod over to improve air flow and still stay safely under 170cc. They also had to use a 2.02 intake valve. When finished they flowed around 280 cfm. Shape, runner cc, and valve size dictate turbulence and flow. The head he ported flowed around 40 cfm more than out of the box but that labor for staying within the Super Stock rules come at a cost. Someone asked him and he quoted a 10,000.00-12,000.00 price. I won’t post his pictures but please check out his work on Facebook. The shape of the exhaust port totally changed.
