Rocker ArmsHarland-Sharps on the street?
Came across a good deal on a set of Harland-Sharps, so I picked them-up. These be for use on my mostly street 471 stroker.
My first preference would have been a set of stainless steel Comp Cams Pro-Magnums. A good deal hasn't presented itself, so I nabbed the H-S's.
So, should I be concerned? Should I start looking for someone who wants to trade? Should I run them and forget about it?
I don't have an answer for you, but I had a set of H-S 1.6's on my Chally to start off with. My car is 100% street. I changed them because I thought they made too much valvetrain noise. I went to Comp Cams I think. But anyway, I'd be curious to hear about the longevity also.
been running harland sharp in my 440 for 3 years with no trouble. Not a daily driver though its a weekend car.
im interested in this too. my new motor will have some HS's on it, hopefully drop it in the car in the next couple weeks. im gonna run em and see what happens, lol. i dont think they'll be a problem, never heard anything bad about em, even on the street. then again, i havnt tried em yet. CHIP
I've heard nothing but good things other than the previously mentioned noise. Never heard of anyone running any real high mileage on them either.
Why don't you ask Harland Sharp?
i have them on my 440. i only pt about 1500 miles on them so far and i haven`t had problem. they are noisy though, the motor will be even noisier when i put the solid cam in too!!
I have customers who have been running the same Harland Sharp setups for years on the street with no problems. I have a set on our race car but it does not get a lot of miles on it though (1/4 at a time!). If you need anything or have further questions on the Harland Sharp products send me an email and I will try and help you out!
I have 7000 miles on a set just took them off and inspected them and they look like brand new
Sounds like I can run them with confidence.
DynoDave, yeah the noise lessened but because I went from 1.6's to 1.5's, I felt more comfortable with clearances and I went to a fat full turn on the preload. I had the H-S's at 1/2 per H-S recommendations. So in all fairness I can't say that it was the switch to steel from alum that did it. There is still some noise even after double checking the steel ones, but I'm thinking the alum heads maybe transmit more noise? This is my first alum headed engine, so I have no prior experience to compare with.
Found aluminum rollers even cheaper then the HS in the Jegs catalog. Proform if i recall. Under 3bills. Anyone have any info or feedback on em?
I would not even be concerned about running Harland Sharps on the street, they will out last std rockers on the street, just maintain the engine and lash them up regularly, and they will last you forever,
