Yep Rob yer right, pretty small for what I mostly do. But I'm well pleased with what it has done. Plus the fact we've exceeded the customers desires.
Doggone it Marco, you're a tough audience.
With the Victor intake the engine was begging for more carburetor. But that wasn't what we were up to. We were testing the difference between the Victor (this wasn't a good Victor, it has had plenum work to it that had it actually lose power) and the port matched RPM. A ported RPM will hold it's own with a good blended Victor to 6,000 rpm. We've tested that on a 496 stroker.

You cannot race dynos. For a test we took an engine that made 598 lb-ft and 585 hp on our dyno and the very next day ran it on another dyno.......617 lb-ft and 600 hp. I like his dyno better if we are racing dynos.
