Dyno - headers

Another test I'll do is the 4500 to 4150 adapter with a 3 circuit 1050 with the fenderwell headers, then both my carbs on with better headers.
Will be testing some spacers however I don't have many to test, I bought a 2 inch super sucker merge but I figure with annular boosters that maybe another upstairs power loss...or rpm limitation but I don't know for sure yet
