The people I know with aggressive solid rollers seem to adjust theirs regularly. Like every few passes and sometimes every one if it seems to be off a little, but they have a few more cubes, run race fuel and make over 1200hp at over 9000 rpm.
I am not an expert, but I would expect you might get away with doing it every 500 hundred miles, that is if you plan to make 900hp NA on pump gas. I would imagine to get 900 hp on a low enough compression for pump gas will need a fair amount of rpm to do it, which means a very stable valve train.
You are the engine builder I guess you can correct me if what I have seen is incorrect, but I would think a lot of people would be running solid if it needed little maintenance. Including me.

one thing that most people forget is that pretty much every import made had a solid valvetrain.
somewhere along the line came this huge wives tail that solid valvetrains need adjusted at every stoplight.

here is my take. If you have to adjust the valves something is wearing out. In a roller engine you should have no wear after the valves are seated in. My 2500 hp 9000 rpm race engine got the valves adjusted once a year. If you have to adjust the valves-there is a problem and it needs to be fixxed.

Just one small correction.
Stage 7 made 671/632 and it was an ERL Superdeck 468ci built by HKE.
Unless he had a different dyno sheet than the one I have. Still amazing numbers on pump gas.
I happen to have the top end off that motor. His updated one will be even crazier.

Your right about the number & the block but still nasty N/A numbers.
I can't wait to see his new update
Care to share some info/graph fro your setup
Define "well built".....what cam, heads, intake?
I assume N/A?
Street?
Strip?
Pump?
E85?
What's it going in? Fbody, you're going to run into intake challenges. Vette....a different set of issues.
The heart of my 460 are the heads. I (we) think the intake will certainly let them do what they're supposed to do.

How many passes would you make with your Solid Roller 2500hp engine before adjusting valve lash? Is there a way to equate that to street driving? Idling, sitting in traffic, street miles, etc?
I've been wanting to run solid roller on one of my street cars for a long time, but I've always gone hydraulic roller for fear of what Rampant described.
I'm liking what you are saying.

I used to run solid roller cams in my street cars 15 years ago as there was no hyd roller stuff that would handle 650 lift at the time. Anyway I would check the valves every 10,000 miles or so. usually didn't need adjusted. Materials have gotten alot better since then, so there should be even less wear.

Thanks....getting a little anxious myself.
Shawn and company down there have had their share of challenges (and patience) with this build, but I have no doubt when it hits the dyno, not too many stones will be left unturned. Def gonna make some noise

I have nothing compared to the mentioned motors but here is a link to how it sits now. I am working with Kooks right now to see if there is a way to have thier 2" mate up to thier catted true duals, hoping that will free up a few hp. I live in Canada and they are really strict on the emissions. I do have a status that allows 1981 levels, but must have all the original equipment installed. Though I did find a loop hole on the EGR. If I use 3 way cats I can delete it as long as it meets the 81 levels.

My old man keeps telling me I would need to check the lash every 500 miles. I usually just laugh. Should only be a problem if the geometry is fudged up

Very nice setup

Back in the 50's and 60's up till 1972 when GM was using solid flat tappets in the Corvettes, they used stamped steel rockers with just an out of round locking nut that was and still is notorious for backing off regularly.
As I'm sure you know, todays shaft systems share nothing in common with this yet people still talk about it without knowing where the "wives tail" came from. Reminds me of the 3/4 race cam crap. Most people have no idea that was a real cam from Isky.

Thanks for sharing, and sorry to the OP for the highjack!
BTW, I've seen 502's make less than 700 hp, you would be getting it done to make 800 hp on pump gas with a hyd roller cam and would require something like a Mast intake or a Holley LS3 intake with dual TB's and some large heads flowing over 400.
