I've got Crowers if you get in a bind..

Solids will require periodic adjustment (especially initially); and would also require a cam replacement, as the lobe design is entirely different.
For the 25 times/year an individual may run down a 1/4 mile track I see NO reason to be concerned about changing to a different lifter design. In fact the low r.p.m. TQ loss in a D.D. wouldn't be the best move in a heavier truck, anyway.
Extended higher than normal r.p.m. operation (such as in a road racing application) complete with high spring pressures, may benefit the most from a change like this.
This conversation won't be entering into the benefits of "lofting" lifters, as I have my own take on that.. Use the correct cam grind to start with.
We are talking about a h.p. street engine...right??For a DD, the o.e.m. lifters are just fine..

I doubt you could pass a smog test with slow bleed lifters. That's one of the reasons they can pass the sniffer emission test with the current factory cam profile. The fast bleeds at low speed/Idle are doing what their designed to do bleed off some small amount of duration. At higher speeds their is not enough time for them to bleed. Oil viscosity will change the bleed rate also. The factory rocker arms are rollers.
Just my 2 cents,

Yes that's why they did it. My trucks wouldn't pass emissions anyways they both don't have cats, but we don't have emission tests here yet
thanks for the input guys:rock::rock::congrats::congrats::burnout::burnout:
forgot bout the lobe profiles being different between the solids & hyd.
if it would be a good set up for a regularly driven street engine, would not mind the valve settin every once in awhile.
we just have OBDII emissions testin here. so no codes, no prob.
its been mentioned on several occasions that our engines don't settle in till around 40,000 miles, not real sure what that means.
just turned the big 60 on mine & the engine seems alot quieter than when i got her. less noise on the top end, but seems like smoother/lopey idle

Yea I'm hoping for less noise and for it to preform alittle better overal..... that is until I save up the coin for my strikers
Harland Sharp rollers
The stock rockers are 1.5-1 . Are the Harlands 1.7-1 ? And would that help performance any by going to a 1.7 roller?

Hey Huck. I forgot to answer your last text.....I'm not much of a texting guy! But, the answer is: nothing special planned for winter.....yet!
O.e.m. rockers are also 1.7.
Strikers will be available again shortly (In answer to your email). They come with shaft-mounted custom roller rockers that work ONLY with the Strikers. I.O.W. the Harlands won't work with them.
Roller rockers are easier on valve guides because they reduce side-loading, reduce overall friction, etc; but any power increase would be slight. In back-to-back dyno testing, I've never seen ANY power increases... Are they better than a non-roller tip rocker? Sure if they are built properly to start with, full roller rockers are a better design overall.
The stock Gen III Viper engines use rollers rockers, just not in the tip.
If you buy aftermarket roller-rockers, make sure your builder checks their alignment because I think some of the manufacturers have been hiring the blind to check them before they're shipped.
Hardened pushrods (also come with Strikers) will offer a bit of a power gain as they resist flexing at higher r.p.m.
As is the case in most performance engines, "weak" pushrods are a cheap fail-safe for the factories when buzzing a stock high-performance engine to stratospheric levels.
P.S.
Is it snowing up there yet?

Nope !! No snow yet! Just below 0 temps and these trucks love cold air!!!:rock::rock::rock::rock::drool::drool::drool::drool: really hard to get any traction

Woke up to snow at work this morning.
Damn that white shiite!!!! gonna clean up the ole' Slithering Beast and put her away this weekend Next year could be interesting!
Next year could be interesting!Woke up to snow at work this morning.
I am jealous you get to sleep at work....
PS: It isn't even snowing where I am 200 km north of Ft Mac. :marchmellow:
Hey! Haven't heard from you for a while.
No snow here (yet) but they are forecasting a bad Winter...
Sleep?....Oh yeah, I remember that !!!
Damn, and I am 150km southeast for Ft. Mac. At least it has melted this morning.
Where abouts are you? I'm in LaCorey about 18km north of Bonnyville and we got about 1.5" of white misery here!! Almost all melted now!
