Hello guys... I have a gen 4 582ci blower engine that I have taken down for rebuild. Changing from flat tappet to full roller and need some direction on what works best.

I'd like to maintain some sort of idle for maneuvering around the docks if possible. Putting out 5lbs of boost. 10-71 blowers.

Mainly looking for the cam, hydro roller lifters, springs, retainers, etc... basically, the entire kit.

Thanks guys for the help!!

Q

i have a pair of 950hp blower motors with crane 139651 hyd roller cams,isky tool room springs and morrel hyd lifters,have 70+ hours on them with no problems,sounds and runs great,and idels around dock good.

i had a 509 with a blower i used cammotion they were able to choose the best cam for my engine .They also have other parts you need .I had scorpian rockers and had to buy larger valve covers from teague . they didn't work well and i got comp cam magnum rockers.Call them and they can come up with the right specs make sure you inform them its for a boat for the correct separation

I'll second the 651 cam as a good option

you can call any cam builder ie(crane, isky,comp cams ect. They will take youre specs down on your motor and will make a reccomendation on a cam or will custom gring you a cam.

cammotion....ask for skip

Give Bob Madara a call at Marine Kinetics. He is a great guy to work with. He will make sure you have the right combination for your application.

I also say give Bob at Marine kinetics 585-654-8583 a call IF you don't want to mess around and he will sell you everything as a package, my motor with his cam made 1115 hp, idles at 900 rpm's, hyd roller, Smitty
