chassie dyno VS engine dyno, you will have a difference.

that 600rpm/sec sounds abit high, 300rpm/sec is about the norm in which motors should be tested (mine was tested at 300rpm/sec)

was that on COME's engine dyno by any chance?

adding the extra 1" spacer will give you more top end HP & the flow between those two carbs will give you more as well & it wouldn't suprise me if he finds a flat spot somewhere now he has added the extra 1" in the spacer also when he goes to the track he MAY be able to get a bit better by going up 1-2 jet sizes in the secondarys
