I always wondered this as well. Higher lifter loads but lesser lifter travel. Interesting to see where this goes. So for marine is it always better to run the 1.7 ratios? Or on a more mild cam where spring pressures aren't that high be able to use the shorter travel factory style dogbone gen 6 lifters. Say in a simple stock CR, stock bottom end 502? Wondering for my next boat.......wanting to keep fairly stock 502 mpi, add pro flo intakes, better cam, enginequest 320 heads. Plan is to procharged them eventually but would prob run for a season or two NA.

One of them was, so what is the point made? I am lost.

Wait? there is talk that we rigged the dyno or made up these numbers? .... who said that please PM to me...funnt how that can be said when the boat performs like a 600 hp boat, NOT a 700 hp boat.... good lord.

Really? No $hit Banned! for What? I don't recall them pointing any fingers, and there was good tech talk going on! I'm not up on all the "insider" crap and don't want to be! Why can't we agree to disagree and remain friends/colleagues, and enjoy the boats for what they are?

Just my opinion, The bigger ratio will act like a faster ramp, stock spring pressure may not control the acceleration and your lifters will be playing basketball with the cam. There is the possibility of the retainers hitting the valve guides, also a chance of coil bind. If the heads flow more with the higher lift you would gain some power.

It's funny the Bob lovers get all worked up if we mention Bobs name, well he is the person in my case that got me set up, so who else name would I say? Bob was designer, it failed at numbers, he should defend himself, he will not... so if guys don't wanna hear a name who cares, get over it, if I used Gellner for heads, cams, rockers, and stuff then his name would be mentioned... but I didn't There is NO AGENDA for me, I can care less what people think if they want to think that go ahead.

Basically it seems there are MANY shelf cams that will work great for any build, I could have picked Cigrockets build from 10 years ago and had a PROVEN combo with great dyno numbers and also a faster result in the boat, so yes to me there are shelf cams that just work.

I had a hunch, without any fact (when it was first posted), that your engine and Bob's cam was somehow going to be the root of the engines referenced. It was like watching a coming attraction to a movie where you think you saw it already because you can predict the ending.

It goes back to my post on how this whole thread is full of undertones, innuendo's which are later followed by direct comments related to Bob and his cams. It's getting old and seems to be a common thing and I don't agree with the tact. But that's just my opinion so it doesn't matter anyway.

I don't wish you any ill will, I don't even know you. Believe me, I've been screwed by plenty of people in the marine industry over the past 17 years that I've owned boats and worked on them for a living. I saw my father get screwed back in the 1980's as well with his boat... So, it's not a new thing... Best thing I can tell you is to educate yourself so that if/when things seem awry, you can see it coming. Also, don't have too many hands in the pot. You know what they say about opinion's and a$$holes. lol

I don't have anything else to add to this thread. It's a shame it went sideways but it was destined to go that way with the undertones.

you are making it more then it is, lets just say for one second you spent over 30 grand on engines, then find out they make the boat SLOWER then before, after Bob said 700 hp and will be WAY better then my old engines, then find out they are not, would you not try to get to the bottom of why not? Now I see that someone says the numbers are skewed? well the boat is SLOWER then it was with 598HP engines so how can that be true?

dude bottom line is Bob did not deliver, and if was anyone else it would be no big deal, god forbid Bob messed up... if you are so smart why don't you tell me why I don't see even close to 700 hp?

Take it to PM I will have it out with you, I don't feel like being banned because you think we are out to make Bob look bad...

If your intent is to PM me and "have it out with me" as you say, don't bother because I wont respond.
