my set up with added Hyd flat tappet / RPM range: 2300-6500 / Adv duration: 284 int 296 exh / Dur at .050: 240 int 246 exh / Lift: .507 int .510 exh / Lobe separation angle: 110 /. . will this cam work well with my cumbo? what kind power will i make? what will it run?

 

I don't think you have the cylinder heads or compression to use that GIGANTIC cam, and the single plane.
I don't think you'll go faster

 

I think u need to build the motor to run those parts you mentioned they all interact with each other to make a balanced part otherwise you end up with a dud or worse something that doesn't run at all.

 

ok i change the cam im asking about. its at top. will that one comp cam say it will so what do yall think?

 

That one would probably work ok. You have AL heads? You've just barely got enough compression for that with AL heads.
I'd use a solid cam though, once you get into the higher RPM, solids work a lot better. A solid flat tappet is comparable in price also.

 

i want a soild lift cam but i wanted a cam that with spring and all. but please help on this. what all do i need to change spring in my heads? how hard is it to do? i have done it before but i dont know about install height? my heads are al heads
