:lol: I thought you were sending us to the Trick Flow news room.
Are you putting ported Speedmaster heads and intake on your 422?
I think that's the only way you can really compare Speedmaster products to Edelbrock.
I guarantee you it would be easier for me to get [email protected] and 315 cfm out of. Once I go past 320 they even out but I like the valve guide fit better on the speedmaster heads for sure.
