Well I have not been able to reach Bob. However I did talk to Joe Coretti who said do not go over 650 on the Lift with HYD rollor lifters. He said my duration should be about 245 -255 @ .50 and 650 with LS @ 114 and 1.7 Rockers.
What do you think?

That is the reason for the 1.8 ratio rockers, it keeps the cam lobe lift and the ramp speed down (good for hydraulic rollers) but puts the lift into the valve for extra air flow. I agree do not exceed .650 lift with hydraulic roller lifters.

I am running a Hyrdaulic now. .647/.647 and 252/262 @50. I dont know what my LSA is. I would say that what you have there is a good choice, but if you have dry exhaust i would throw some more duration in there.

Rudy fixed me up after loosing a brand new engine with only 19 hours that was built in Waukegan, IL. I picked the original builder because they offered a 2 year warranty but after having to pay $8K for a rebuild they have not stood behind their work. Why even offer a warranty? There may be more info forthcoming on this situation.

Rudy's engine is top notch! He educated me too.

what are the CI's on your motor? Are you fuel injected or Carb? How is your Idle? Thanks

I just got off the phone with Bob. WOW what an education and a great guy to talk to. Bob asked questions that no one else had asked. Everything from how I plan on using my boat to what exhaust, Head type- flow and EFI I was using. I underestimated how the cam really works. If I had not already ordered my motors Bob would have receive my purchase order after all that. Building a low maintenance and dependable motor was always my number one goal. I think Bob filled in all the missing pieces. Thanks Bob

I idle at 850rpm out of gear, 500rpm in gear. It doesnt surge, has never stalled, just lopes along. I am running 10:1 compression and pretty conservative timing at 33º total.
