How to prepare for engine dyno?

None of them made any appreciable increase in power vs not running one at all. My AirGap intake is gasket matched and some light porting work was done to the heads. Carb is a 800 cfm Edelbrock Thunder series.
Nice! That means the engine didn’t need any help. The intake has enough plenum


I plan on looking into these more. I never thought I'd say it the whole time I was building the engine, but while 500 hp is fun, I want more!
Yup! Your hooked! Me to.
