You wouldn't run a stud girdle with shaft rockers,

Yes after some research I see that as well Thanks for the information. It looks like a rocker girdle adds some more headache to a valve lash...... Starting to think about a Hydraulic setup, after diving into some solid roller searches it seams like a very labor intensive and expensive choice to run the solids. Changing lifters every 30-50 hours!!!

i did mine at the beginning of the season,,and even then i never had to adjust mine,,roller lifters are easy on solid cams,,it thewy were flat tappet then their would be a little ware..Btw 50 hrs only if your at high rpm for that long,,i have gone 120ish then just went and refreshed everything....you can make it easier if you got rid of the stud girtles and those style rockers and went to a T&D or jessel style shaft rocker..

Okay so the cam card reads .714 gross intake lift .690 gross exhaust lift valve lash .20 lash adjustment both sides, intake 260 @ .50 duration and exhaust @ 268 .50 duration. Could a similar setup be done with a hydraulic over the solids. Again motor is limited to 6k.

I've ran the same Isky solid lifters since '06. I just sent them back to Isky last month to get them rebuilt $20/ea or $320/set.
And I'm putting those solid lifters on my new hydraulic roller cams this season. Don't be scared of them, check the lash this summer and enjoy the boat.

Thanks Jason, I think I will take that advice

20 hours is a good interval & should just be a quick check to verify & If your re-setting Lash better dig a lil deeper cause you have other problems going on

good advice,mercury uses solids in a lot of their high hp engines.
