After further research I’m gonna have to say your assessment on Hyd. Rollers is horse ****. Per a cam grinder that has been custom making cams and building his own engines for Probly longer than you’ve been turning wrenches. “The benefits of a solid roller over a hyd. Roller are negligible if the grind is correct. Plus checking lash on a solid is more frequent than a hyd. Roller. For a street motor a hyd. Roller makes perfect sense. Plus good bushed lifters for a solid roller are 1000.00 vs 500 for nice hyd. Roller lifters.”
You missed the point entirely regarding Hydraulic Rollers Vrs Solid STREET Rollers
specific to BB Mopars ?
Not surprising given your limited experience.
and NO....
your Cam Guy has NOT been Grinding Cams longer than I've been turning wrenches.... and I've Dyno'd More Hydraulic Roller BB Mopars than he's probably ground Cams for BB Mopars in his Life
It's the "condition" of the Lifter Bores in the 50 year old Blocks dummy !
Hydraulic Roller "Lifters" rely on a patent Oil Pressure supply to maintain "pump up" against ever higher V/Spring Pressures a Roller Profile requires....
That's why ALL Manufacturers (Ford/GM/and later Mopar) when they went over to Hydraulic Roller Cams
Modified the Lifter Bores in the Blocks making them LONGER/DEEPER to provide more "Seal" area integrity around the Lifter and reduce Lifter Bore leakage of Oil Pressure "out and around" the Lifter Vrs being directed into the Lifters to maintain pump up.
GO LOOK at the Lifter Bore LENGTH differences in "Roller" Blocks and NON-Roller Blocks in Fords & GM's etc ?
Will Hyd Rollers run fine in NON-Roller Ford & GM Blocks... YEP they do !.... but more because of the Oil Gallery positioning being far enough removed from the Top & Bottom of the Lifter Bores.
Now...
remember here....
1.) that BB Mopars were NEVER offered with a Hydraulic Roller Cam (Short Lifter Bores)
and
2.) Their HUGE Oil Gallery through the Lifter Bore is very close to the Bottom of the Lifter Bore.... which on most BB Mopars if you "inspect the bottom of the Lifter Bores directly below the Lifter Bore Oil Gallery you may
SEE the "problem" with patent Sealing of Hydraulic Roller Lifters in BB Mopars ? That being a 1/2 moon WEAR mark in that area of the Lifter Bore ?
GO INSPECT the sides of your Lifter Bores BELOW the Oil gallery in YOUR 440 BLOCK ?
How much distance is there between the top of the wear pattern from the Lifter going up & down 10 quadrillion times in the Lifter Bore to the Oil Gallery ?
Bottom line here.... I could give a f*ck if you want to repeat all the mistakes guys make trying to build Mopars listening to Chevrolet advice ?
Have at her there nimrod.... go blow up some more of ur junk ?
Too soon ya get old... too late ya get smart huh ?
