I ran a 700 lift roller cam on the street for years. 245/590 Isky tool room springs. Zero problems. Lots of 15 to 20 miles type jogs all the time in it. And lots of passes at the track every season. Go for it

I would drive the hell out of it and check lash / change the oil every 500 miles. If the fuel/timing curve is correct and you have a coated gear the frequency of maintenance could be extended.
If you drive it hard check things over often. Much easier to catch a broken valve spring under the rocker cover than picking the pieces out of the oil pan lol.
Do you have a cam card? How far is the block bored?

I have done 6 drag weeks with solid roller lifters. Stay on top of your lash, make sure the springs match your combo, and keep your ears open it will tell you if it something isn't right.
I usually check them a few times on drag week, they get loud after hours on the highway, and in my head I always think one is really loose, and it never is lol. Hours on the highway @200* gets the oil and everything nice and hot so the lash gets wider than normal I am sure, it is usually all good the next morning when I check them.

15-20 miles ok. What about 75-100 miles. Just nervous If I were to buy it, I'll munch something rather quickly You can find all sorts of stories. I know plenty of guys who have tore up engines because a solid roller lifter came apart while they were driving down the freeway or around town. Then there are guys who drive them a lot without any trouble. As others have said, it is the details that matter. Good lubrication, proper clearances, picking the right lobe, matching the springs to the lobe, using high quality parts, etc.

All good advice - keep after the lash, any 1 valve that changes quickly may be something getting ready to die. Loose lash is what kills tappet rollers. If you don't know what quality rockers you have, get good ones.

It’s been years since I ran a solid roller on the street. But when I did the standard week end was over 200 miles. I didn’t own a trailer and the town I street raced in was 40 miles away. A lot of the time we would go on Friday and Saturday night. That was 160 miles to get there and get home, not counting cruising or racing once we got there. I put 1000’s of miles on that engine. Broke one tie bar in all those miles. It had one thing that I think is a very good idea. The engine had a rev kit. Basically an extra set of springs that kept the slack out of the lifters. This was in the 70’s so I would think lifters are much better now than then.

Whose rockers come in the -1 kit from Indy? That's what is on them. It depends on when those heads where sold by Indy, if they are black or deep purple extruded aluminum , no needle bearings on the shafts, their probably Doves

If it were mine i would find out exactly what every part of the valve train is. It is the whole combo that makes the difference . If the rockers are doves they have a reputation of limited strength. Probably OK for a flat tappet cam or mild solid roller that won't need a lot of spring. Once you know what is in the motor you can go to a knowledgeable engine builder and come up with a plan. IMHO pressure fed lifters are a very good idea. A cam with endurance type lobes or milder also. I keep a close eye on lash and am very carefull to check at as close to each 90 degree move, 90, 180 , 270. 0. Cams do flex under spring load and the bigger the springs the more important this becomes. If you see a valve get loose by more than .002 start looking for the problem. My last inspection #6 intake was .003 loose. I have Jesel paired rockers and the intake rocker felt fine till i tried to rotate it full circle on its' shaft. On further inspection the rocker shaft was galled and the roller bearing would have gone bad next, filling my motor with nasty crap. I once had the needles wind up in the oil pump , ruin all the bearings, scratch the cylinder walls, and broke the pump drive Shaft. So now i keep notes and if anything changes even a little like + .001 or close to .002 it gets rechecked again very soon. Any more movement and i know something is going away.

I will add that having pressurized oil to the bottom of the lifter greatly improves longevity.Also keep spring pressures pressures well under 700# over the nose and a non aggressive lobe. I sent mine back to be rebuilt with 5 years and about 7500 miles and they only wanted to rebuild 3 lifters,I told them to please do ALL of them at $12 each!!!
HEMI-ITIS has no cure. My condition is fully BLOWN!!

Useful rev kit springs are still available, but no specific attachment hardware (or even dimensions) to install. Typically, this levers against the underside of the head casting with seats for the springs following the tappet bore locations exactly. Somewhere there are SBC & BBC install pictures?

Aggressiveness of the lobe, quality of parts and RPM are going to determine maintenance schedule and longevity of parts.
Max effort? Fun cruising car? Cam can always be swapped to one that better suits your needs/goals.
.660/.640 is not that big and the springs seem fairly mild. Need to know lobe design.

If the results don't match the theory, change the theory.

I've driven my .680-.660 276-281 @ .050 ISKY solid roller up to 1 1/2 hours for a local movie shoot in L.A. County when I live in S.B. county and many miles since then and a few hundred passes as well. Gentle lobes and frequent lash checks/setting go a long way. Started at 210/530 pressures and stepped up to 245/600 7 years ago.......

Do you know what the duration is at .050 lobe lift and what lobe center the cam is ground on?

I have a set up for a BB Mopar where the spring for the rev kit seats into a retainer made into the push rod.

I'm guessing that those are .050" durations? They're very far apart.

You still know as much nothing now as you did before talking to him. If you want a good answer, you need the facts. Bust out the tools.

and that was the engine builder, not the owner of the engine. Would there be a cam # on the cam?

Are you saying neither the person who owns (owned?) the engine or the person who built the engine can tell you the specifics of the cam that's in it? Nobody's got a build sheet or a cam card for it? That's "questionable", at best.

I talked to the engine builder today............. Said it a solid set-up that would live on the street with proper maintenance. Said it was actually built to drive on street, with in reason. Sounds like you’re good to go. Let ‘er rip.

You need a good converter that is built to match your combo or it will be miserable to drive on the street. With too tight of a converter, you can have idle issues as in needing excessive idle speed to keep it from loading up and trying to die at a light without putting it in neutral all the time. A properly built converter will not have excessive "slip" in normal driving and will be perfectly streetable. When you jump in it, it will flash and get you into your powerband instantly. Lots of downsides to having too low of a stall, no advantages. Ask me how I know! Find out what you cam is and talk to a reputable converter builder about what you are trying to do and I doubt any of them would recommend a "tight" 10", that probably stalls around 2800. If that cam is a 280@50, I suspect a 3800 stall would be on the low side with a heavy car, but I am certainly no expert.

Ok, last question. If I buy this thing and put it in with a tight T/A converter in my heavy car (3.91's), and it is a 270 or 280@50 cam, is it gong to be soggy around town down low? I know there's a trade off to horsepower and puttzing around the street. I know the actual cam card would be an immense help, and I'm still trying to get it. Couple of things. 1) consider starting a new thread with all the info needed. A tight T/A converter doesn't mean much, and we don't know what your goals are for the car. 2) Regarding this thread, just put the right cam in it for your purpose. If we talk much longer about it you could have had it done already. Based on the limited discuss so far, this sounds like a candidate for something like a Comp -5 cam in the 250s on a 112 with Isky 9365 springs, if you keep it under 6500 and lugging around town is the main plan..
