dont know the specs on the supercharged 575 cam so I really cant say..
Just have read on here that the cam on them is on the small side.

Mine are:
gen6 roller
580/590 with 1.7rr
[email protected]
230int 236exh 114lsa

Regardless it doesnt really matter to me as it does what I want it to..
:)

Thank's everyone for your responses!

i must admit your cam is closer in duration than i thought, the 575SCI is - Crane 13h000060 240*/240* @ .050 .559/.559 lift
adv duration 300/300
grind # h-240/329-10 t1.2

don't get me wrong i'm not saying it won't work well with that cam because it will real well. the blower will like the 114 C/L, good luck with the build and if you dyno it be sure to post up the results!

Thanks, I dont know if I will dyno it out of the boat but
will probably use mph to gauge my increase, I do have a
wide band A/F already installed to help tune plus fuel pressure and
vacuum/boost gauges.
Right now my best was 69.8mph@5200 with a 4 blader ,boat weighs about 6000 fully fueled which it was for that test run but I have lots of slip in the midrange,(high x dim)
Im going to try a 5 blader plus the blower, hoping for some solid increases in cruise speed more than anything and 4-5mph on top end. I also just bought some 28" long K-planes for added stability.
Should be a fun summer next year..
