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. 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 $$$. "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. 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.

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 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.

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.

Just had my Indy heads machined for spring locators and when we checked the springs all were same as new. K-motion told me direct not to run the K-950s on the street, they will break. I have a set of 9385 Iskys I will try if the comps go down, Isky says they will hold up on the street also. I have 600 miles on Indy bronze dist gear and shaft. It shows slight amount of wear. Galen

I`m on the same set of Isky solid body drop in lifters and run their rollerized cam button touching a stock timing cover............a few thousand miles later all seems well and thats w/.680-.660 lift and 275-280 degs. dur @ .050.....mileage sucks but what a blast to drive. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

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

Additionally the natural back-n-forth will wear out that bronze dizzy drive a heck of a lot quicker.

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?

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. Quote: 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. Rich H. Esse Quam Videri

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
