Hydraulic roller cam opinions

[flyinlow]

I was interested in a hydraulic roller cam for long term street use.

446/ 10.5 cr./eddy heads /rpm intake/headers / a518 trans/ 3.55 axle    Current cam  Lunati Voodoo 60303  1800-6200 rpm hyd. 

I want more lift , slightly lower rpm range ( OD trans with lock up now, alot of time at less than 2000 rpm ) , descent idle , better milage , low valve train maintenance and use any synthetic oil .

Possible?

Sure...anything is possible but the swap to roller is expensive. You also have the bronze gear and electric fuel pump to contend with. 

Roller's are not completely maintenance free....even hyd rollers.

Yea , looked like close to $1500 . 

Hyd.roller cams do not have a fuel pump eccentric?

I read some of the other posts talking about 3k mile lifter and spring life. I assumed this was for .700+ lifts and much higher rpms then I subject a street cars engine to.

Yes, the roller cams have an eccentric/lobe but the core is Billet and will wear the stock pushrod down in a few hundred miles...not good. 

A few vendors sell a brass tipped fuel pump pushrod but i haven't heard any long term reports. Most guys just go electric fuel pump with a roller cam. 

The 3k service interval applies to solid roller cams...the hyd roller sticks use less spring pressure so they're not hard on parts.
