Is RM Builder a cam manufacturer or engine builder? He has had great posts, just curious.

very knowledeable cam builder , he did say awhile back he might staet building engines ?

I would say RMBuilder/Bob is more of a cam consultant with some of his own proprietory cam lobe designs. He takes all your engine specs...i.e. cubic inches, uspercharge or naturally aspirated, carb size, comp raito, heads and head flow, type of exhaust system you're using, application the boat/engine is being used for....blah, blah, blah....and he will have a cam cut and custom fit for your application.

Bob is very intelligent, knowledgable and proffesional guy. My engine builder Dave at WESCO uses Bob's cam designs. Offshore engines are the only thing Dave builds and so far he probably has about 40 various marine offshore engines out there with Bob's cam designs.

So hydraulic or solid? Which way are you leaning?
