Can I get that with Grich's autograph on the write up?

ANY opinions you want to share on the cam/event timing/lsa and/OR bottom end clearances/dimensions are valued input... I learn by watching/listening...

To be honest this cam would not work well for most engines. The exhaust is smaller than the intake duration and the LCA is not as tight as you would think. If I remember correctly it is on a 108 and I think we put the intake at 108 or so. We tried advancing it on the dyno, and it did not like it. Also, this is a hydraulic roller with a non aggressive profile. We talked about going solid roller and going crazy with the profile, but we did not want to have to set valves all the time on this thing and so we went conservative. The cam would have been a little more standard if the idiot porting the heads knew what he was doing. I just smoothed some things out and tried to keep things nice and even. I gave the flow numbers to the cam guy (Chris) and this is what he sent me. The strut angle is somewhere between 7.5* and 8* and the back of the strut is a little further back from where the last boat was based off of what we learned on it. We did not do anything super crazy with the rudder either on this one. I can't remember if the front of the turn fins were 94 or 95 inches, but they are around there. We were conservative with the rocker and I think the plates are right about 7" right now. Engine placement is close to 34 or 35 inches and I think the v-drive is around 97 inches. If you need more info than that I guess I will have to look at notes instead of going off the top of my head. LOL

It is funny, I did not know about this post or the link Buzzz put up until today. I forgot I was even a member over here. Learn something new all the time.
