For the W5 lovers
My before numbers on my Edelbrock heads maxed out at 243cfm so I’d say I made some nice gains. There are very few guys that have done as many flow tests on Mopar small block Mopar and Speedmaster heads. The reason is it’s lost time and money to guys in the business. But for years o only did my own stuff for my own cars so I was out for max effort. How many guys in the business still race??? Not many and those that do test n tune twice a year or hit a Mopar event.
