Is roller tipped rockers worth the money? Do they improve performance?

No performance gains.

You will not net any performance gains..save your money.

And the 'full' roller rockers improve performance?

What is the build of the engine in question?

Well now you guys say it....after I bought and put some on. ;) Oh well...they look cool if nothing else. Wouldn't they extendend the life of the valvetrain by making it smoother though?

All that roller tip "hype" is crap..you will never see any difference in ET or MPH using them..I will say this though,they are cheap,and sometimes they are almost as much as a set of stamped rockers so I guess if you measure dollar spent vs. what you get,they aren't bad if you need rockers.If you all ready have the stockers,save your money.

I do figure CC's inexpensive cast magnum roller tipped rockers are closer to being what they say they are ratio-wise vs the cheaper stamped stock type ones, that's all.

The lost wax casting process is a very accurate way of making something, imho..

Plus, the CC Magnum cast roller tip rockers are much stiffer than the flexible stamped stockers. (reference Vizard's books).

The magnum rockers are the only roller tip rockers that are worthwhile, IMO.

The ratios are much more accurate than the factory rockers.

Thanks for the great replies. I failed to talk about the motor I'm building. It's a 67-327, steel crank, flat top pistons, crane h-302/480 lift 1.5 arm ratio cam, performer carb, performer intake. It's for my 65 Chevelle w/ th350 stock peg leg. My machine shop says that the roller tips are better because of the high lift cam. He said it will reduce ware and tare. He said that Crane has a pretty good one. Actually, I returened it to the speed shop and got ARP bolt sets on sale (swapped). Now I'm wondering if I should get em back?

Clayboy,you don't need to get 'em back,trust me.My 4000 lb. 454 powered sled does just fine with stock rockers..ET in signature :D

I know you already have a cam BUT please CONSIDER no more then a 268 to 274 advertised duration hy- cam for the little motor b/c IMHO, that's all the little motor really NEEDS to run like Jack the Bear!!!

AND you really need a solid cam to rpm her above 7,000rpm which it will do fine with no more then a good set of cheap Z- springs, (-142's), if the solid cam isn't hairier then a good old stock, 30-30 Big Duntov, or Fuelie cam...

The little motor I gave my nephew was a .040" over stock, 327 with about 10 to 1 CR. and no more then a Crane/Cam Dynamics, what I call a "Little Fireball" cam, (216 or 218 at .050" duration), a set of cheap 1.625" four tube, long headers and a cast-iron 300hp/327 AFB intake with a cheap aluminum adapter to mount a 600cfm, Holley 1850 vacuum secondary carb. ran GREAT!!

My car is a Camaro '67 SS/RS, M-20 and 3.31's!!

You get her wound up AND hold on!!

Been there, done that!!!..

PS., My nephew still has the Crane/Cam Dynamics cam, too stuck somewhere all greased up but no matching lifters...

Benefits of stock rocker:
-Cheap

Benefits of roller tipped rocker:
-Less valve guide wear
-Less wear on rocker
-Less wear on valve tip
-More accurate ratios
-Less flex with high spring forces

Your engine may be "fine" with a stock rocker, but that doesn't mean it wont do better with a aftermarket type!

After giving this matter some time to stew, I believe you guys are absoluely right! Hell in 1967 GM used pressed in studs and stamped rockers for the most high performance engines. Guys like you are still kicking butt on the 1/4 mile with old school stuff thats proven. When a po' boy modo bitch slaps a big buck modo, thats really exciting to me. graemlins/hurray.gif

Your engine may be "fine" with a stock rocker, but that doesn't mean it wont do better with a aftermarket type! IMHO,any of these aftermarket companies that produce these roller tip rockers are probably hoping that no one is checking their manufacturing tolerances..so all this less wear on this,less wear than that,etc. is all moot unless any given set of stock/stamped rockers can be compared to a roller tipped/or full roller set.If you think about it,all rockers are aftermarket,stamped steel or otherwise..and again,do you know what their QC specs are on ratio accuracy,etc. ?

i remember the 67 impala my dad owned had the 327 4-barrel option and i was absolutely impressed with that motor!he would wind'er out until you thought she would blow but she just kept winding higher and higher!he eventually sold that car for peanuts..man,i wish i had that motor!what a peach! :D

You've never lived until you ride shotgun in a '58 Vette Convert with no more then a '64, 375hp/327 F.I. motor, four speed and 3.08's AND a good old Isky Z-30 cam still climbing at 7,200 rpm and between 160 and 170mph!!

And I had to shift for my long gone crippled Buddy that night!!!

YES, you can hold a short stroke SB, (265, 283, 302, 307 and 327), down until you get worried and then push on down some more!!!

My old junk 301 would go above 7,000rpm AND just talk to me!!!
