600lb springs, comp lifters should be ok. Crane lifters are no longer around, so Crower lifters are the best lifters under $1000. I have not had any problems using Milodon bronze gears. I drive 7000+ miles a year and haven't had one go bad, yet As for a cam button, I have only used gear drives with roller cams on Mopars, but make sure you get a strong cover like Indy, AndyF, etc to handle the button. I don't know about the springs. someone else will have to help you with that.

I use comp 829's in all my street cars.They see maybe 3,500 miles a year.I have a set in my wagon now that has 6,500 miles on them no problems.I have a ton of spring on the car too.Idle time is what kills the springs.
I have seen no difference in the dist gears.All seem to be good.
I have only bushed one block in my life.It was a Hemi that I had a ton of money in.I think it is a waste.I've done maybe 30 that ain't bushed NEVER a problem.
Just use the cheap nylon button.

FWIW,
When I was trying to decide on springs for my roller, (which I dont know if I'll ever use, due to not having good rockers) I searched around and was told Isky springs seem to last longer than Comps. Dwayne also said he likes Iskys over Comps. I found a set of dyno time only Isky Tool Room springs on the bag. They pressured OK and are on the heads at the moment. Dont know if that really helps you.
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

my one suggestion would be, have the springs checked to make sure they are what they say they should be. someone here i know checked comp springs and they were all over the place, called comp and while on the phone they were spitting out numbers all over the place too, he actually asked "are you checking springs with the same part number" so like everything else, check it before you use it
i'm a believer in big pressures too like the others said

Ive researched the "bushing the block" deal for the last couple months...
99% say not necessary ( CHECK YOUR GEOMETRY) , and that includes a couple big engine places.
and... Thumper has been running that thing for a long time on the street-- theres some honest , real world info there

How much is a "ton"? 200/600 or 300/800? How much valve lift are you running? When you say "idle time", do you mean time the engine runs at idle, or as in sitting idle for 3 months in the garage?

Are Comp 943 springs durable enough for street use? Not like a "daily driver", but running up say 2000 miles a year on the street/strip.
Never used them. K-1100 springs seem to hold up pretty well fwiw.

Have those of you running roller cams seen any real wear and / or quality differences in the various brands of bronze distributor gears? There seems to be a pretty wide range of prices and I'm not sure what you get for the extra $$$.
I've only used the MP gear, and am on my second one since circa 2002.
Quote:
"Affordable" lifters of choice? Are the Comp 829 solid-body lifters still a good option, or are their other brands NOT costing twice as much that are worth considering? This could be in either an unbushed block OR a block that's been bushed but doesn't have any oil feed holes in the lifter bore bushings.
If you want to spend less than $1000 on lifters, choices are pretty limited. Nothing wrong with 829s or the discontinued Cranes. I've had my 829s rebuilt one time since circa 2002 fwiw. Some here have had good luck with Herbert stuff, never tried it. I have an extra brand new set of Cranes if you want to try them.

What's the simplest & most cost-effective method for setting the cam's end play? I see different types of cam buttons offered, but don't know which ones are more likely to have durability issues in this sort of application.
With a stock timing cover....weld a piece of plate steel (or even a big washer) to it in front of the cam , and set it up (grind it to the proper thickness) so that it interferes with the back of the water pump, and there's your cam stop. The nylon cam button has the best chance of not putting any extra metal in the oil. I have the Diamond/Mancini button in mine, and it did wear a bit into the timing cover over the first couple years because the cover didn't squarely hit the button. Good thing I keep clean oil in it....lesson learned..next time I'm using nylon.

Holy Cow...3500 miles 6000 miles...!!! That's an awful lot of STREET miles..!! my guys have the springs out of there cars in a 1000 miles.But they REALLY use every bit of rpm there cams make and all the time too. You guys driving on the hi way with all these miles racked up. I put spray bars in any engine that I build that is going to see 3000 rpm for sustained periods. Every set of comp roller lifters I've seen have been DEAD after 2 summers of street use with 275/600..Dirty oil with a bit of valve float I'm sure had plenty to do with it. The oil in these 700 hp roller street engines is pretty much used up around 250 miles around here. How hard are you guys driving these engines... My guys stuff sees their red line 30-40 times a night when they drive them. I don't think in all the time I've been building these roller engines have I EVER seen a set of rings go 6000 miles up here let alone a set of valve springs last that long

Like 250/700.Lift is in the 650 + 1.6 rockers.I mean idle time at a stop light with the oil hot as hell and idle at 1,000 RPMs.Kills the springs.
