is it possible to use a hyd.roller cam/lifter set-up with the bridged rockers? this assumes correct length pushrods. Thanks!Bob

Dave, I think most of the newer engines have a non-adjustable valvetrain.The reason for this question was I did not want to go thru the exspense of re-doing a set of heads with studs and guide plates right away.The cam and lifters would be the most major $$$ spent on the rebuild,everything else would be a "parts store" rebuild.Was looking at the coating on cam and lifters...cam was shown at $125, and I'm thinking this is great!I don't hafta run expensive oil.Cough'gag...lifter coating is $395!!!thinkin' the roller set-up be the way to go.Now back to the limits-what is the lift limited to with the bridge rockers?Also,what kind of valve spring pressure before the start to gall or break?Thanks again!Bob

I first have to say I am far from an expert on this kind of stuff. When you asked the question I was thinking something a little more than stock up to something like the comp cam 280H but in a roller grind. I know the 280H cam (490 lift) will work in a 74 360 w/291c heads and not have coil spring bind, valve to piston hitting or retainer hitting the guides. I dont know about the rockers as I am running crane roller rockers so cant say if the slot would work with the 490 lift?
 
I see SK posted and I was going to say the same on the coatings, forget it use the money for roller rockers - and yes they make bolt on ones now so no need for machine work. I hear because they inter lock (I&E for each cly) with each other they can use the smaller bolts as it is shared between the 2 of them.

btw If you could not tell I use the 280H cam in my drag motor and use normal oil with the zinc addative
