solid roller cam comp cam 54-500-11 with hydo lifters? I read where "Coach" and "Pat G" ran a solid roller cam with hydro lifters and made more power. I would like to know if I could possibly run hydro lifters with a comp cam 54-500-11. 1800-6400 rpm, .646/.641 lift, 270/277 113 lsa @50 235/240? Feedback would be appreciated.

Hyd lifter 233/360. So these two lobes one with Hyd one with solid with .008 lash. They will have the same valve motion but different looking specs.

What's the typical "re-adjust interval" for solid roller lifters ?

We have made these SBC BBC engines. We made LT1 for TPIS years ago after running in a street engine for 20,000 miles the lash was find no adjustment needed. They work very well.

I have a buddy did a mild hyd. roller setup in a big block. He had a lifter failure and another set wasn't in the budget he found a smoking deal on a set of solid roller lifters and threw them sounded awesome and never had another failure.

solid roller cam comp cam 54-500-11 with hydo lifters? You can put Hyd lifter on a solid cam. All you will be doing is making your cam duration go up about 8 to 10 degrees along with the lift of .020 to .025. More with a normal solid lobe. So if your cam was to small like the example Hyd lifters could help. It could also kill the power. If you do put Hyd lifters on most solid lifter cams they will have very soft ramps they are not designed for Hyd lifters. I will give you an example. We make a line of Low Lash solid roller cams for all applications they run with .008 lash. The rev high and don’t beat up lifters and the valve train. On these lobe you can run solid or Hyd lifters. If I want the same lift and duration at the valve one with solid and one with Hyd. Here is how I need to make the lobe. Solid lifter lobe 240/366 with .008 lash at the valve.
Hyd lifter 233/360. So these two lobes one with Hyd one with solid with .008 lash. They will have the same valve motion but different looking specs.

You can put the Hyd lifters on your cam. It may help power it may not help. How much lash were you running subtract that and that's how much lift you will gain. It could idle bad if it has long lash ramps like some solid lifter lobes.

Interesting, Kip! I have what I think is an LGM G5X3 cam that I "cam doctored" myself and got these specs:
- IO @ 18.0 BTDC
- IC @ 35.0 ABDC
- ICL @ 98.5 ATDC
- EO @ 63.0 BBDC
- EC @ 2.0 ATDC
- ECL @ 59.5 ABDC

- Exh duration @ 0.050" = 245°
- Int lift = 0.600"
- Exh lift = 0.609"
- LSA - 109.5°
This will be a long one I will PM you.
