How much camshaft can the factory hyd roller lifters and spider support? The engine in question will be a mild build shooting for around .560 lift.
Thanks

Mine has .550 lift with stock lifters...just gotta make sure you set up the springs correctly on the head side.

550
is this a magnum or LA HR build?
on an LA I recommend Iron rockers but have run stock
I recommend oil through the pushrods to oil the stock rocker cups and pushrod ends to hold off pushing the pushrod through the rocker
