BenKey Posted July 5, 2005 Report Share Posted July 5, 2005 It seems I may be going to this type of rocker in the 1.7 ratio size and was wondering if any of you racers out there have ever used them? My builder swears by them, but I don't even know of anyone that has used them. Not that that says much. I currently have a set of Patriot shaft-mount adj rockers. My builder is not too happy with the quality of them. I would have had my motor back Saturday ready to drop in, had it not been for this. So, instead of going with what "looks" to be like low quality parts, I am changing to the Race Gold rockers. Would appreciate any feedback if anyone has any to offer.

TurbochargedBerserker Posted July 5, 2005 Report Share Posted July 5, 2005 That's what I ended up with Ben. They are solid in the quality department. Give Roger Vinci a call -- he did a lot of the research on them and actually wrote the install instructions for Crane. Link to comment Share on other sites More sharing options...

They seem awful proud of them damn things. Don't know the exact price yet, waiting on a call from Rob, but he said somewhere close to $800.

SuperSport Posted July 5, 2005 Report Share Posted July 5, 2005 I read this article about them and i think they sound pretty bad ass, if everything is true. http://chevyhiperformance.com/techarticles/14148_0506_crane/ Link to comment Share on other sites More sharing options...
BenKey Posted July 5, 2005 Author Report Share Posted July 5, 2005 Thanks for the link. Mine are the Gold Race, just not the ones that continuously change the ratio. Mine will stay at 1.7. Link to comment Share on other sites More sharing options...

Remember too that they come with pushrods. IMO, from looking at the Cranes, the stockers, the Patriots and set of Harlan Sharps, the Crane set looked like they had the most R&D and the best workmanship. I wish I could have compared with Comps as well, but couldn't find a local set. Link to comment Share on other sites More sharing options...
wkdivr Posted July 5, 2005 Report Share Posted July 5, 2005 I had the 1.8 Gold Race Roller Rockers with the new "Quick Lift Technology" installed at Vinci's when I was finishing up the Power Tour. They also installed new Crane springs. Made 20 hp on the dyno, but a big hit in the SOP meter. Lots more mid range pull. The guys at Vinci's are a top notch crew, too. If you're in the Orlando area, look en up. Link to comment Share on other sites More sharing options...
matt rem Posted July 5, 2005 Report Share Posted July 5, 2005 I had them in the oval track car for 2 years and never had a problem and that was at 7500 rpm. They are a nice piece,only reason I changed was that I got the stainless steel Comps for free. Link to comment Share on other sites More sharing options...
TBSS Posted July 5, 2005 Report Share Posted July 5, 2005 Hmm....might be worth looking into. Perhaps the 1.8's for me.... Link to comment Share on other sites More sharing options...
marc_w Posted July 6, 2005 Report Share Posted July 6, 2005 I've been running the 1.89 rockers since last August or September? I think VHP calls them the 'quick lift rockers'... while crane simply calls them "Gold Race"... but I'm not 100% certain on that. Mine are simply stamped as 1.8. If they come with the 7.250" pushrods, they're definitely the quick-lift technology... I like them a lot. Setup was confusing the first time around, having never done adjustable rockers before. I ended up putting on too much preload - DEFINITELY only set the bolts finger-tight when you are doing the step where you crank the motor over a few times. I was thinking they had to be light-wrench-tight to take out all of the slack in the valvetrain. I was chasing my tail, as the lifters would bleed down a hair after a short amount of time, they would feel loose again, and I was putting more and more preload on them. All you need is for them to be finger tight. Take a mental note of the side to side and SLIGHT up and down looseness of them. When you start the quarter-turn loading of preload, you will know it's time for another quarter turn when you feel the rockers, and find that they are relaxed and they have that same looseness as before... Power wise - I installed them on top of my old cam, the VHP 210/218 112 .530. I definitely picked up more midrange and top-end. It was a little hard to tell down low. I'm still running them now with my stock cam... but it's been too long to remember how it behaved by itself, and I have other mods installed too...

marc_w Posted July 6, 2005 Report Share Posted July 6, 2005 There are more or less three reasons... 1st would be that in the near future, I should be able to afford a second vehicle to mod to my hearts content. My truck here will be strictly a commuter and tow-vehicle... I wanted my stock powerband back for the exellent towing abilities *** 2nd - I hate to complain about gas when I buy an expensive gas-loving vehicle, but the 15mpg I've been getting lately is just a little too low for my liking. When I take it easy, I'm operating the cam/engine in an area of the powerband where it's kind of "not lit up". (mainly under 1,500-1,600rpm). I don't think the stick is efficient when it's not "on"... so I put the stock stick back in to regain my old mileage back. I was seeing 21mpg "indicated" on the DIC, during some controlled commutes to work, before I started swapping cams around. Average seemed to be in the mid 17's. 3rd - This last weekend was pretty much the last nail in the coffin when it comes to seriously modding daily-drivers. If I can't easily afford a second vehicle - the truck will be replaced with a "simpler" and older truck. I don't want to let it go with any major mods in it, or mods that I can sell for some decent cash. *** having said that, I'm sorely dissappointed with the stock cam since putting it back in. I underestimated the VHP stick. It was only softer than stock WAY down on the bottom of the RPM range, around 1,100rpm, or that spot between 35 and 40mph where the TCC locks up. It was at least comparable to stock from there up to 1,500rpm. Above that there is no comparison. Much more power. Link to comment Share on other sites More sharing options...
TBSS Posted July 6, 2005 Report Share Posted July 6, 2005 Thanks for the in-depth reply, that was helpful. That makes me feel much better about what I have been doing with my truck. I selected the cam I have for more than a few reasons.....one of the biggest ones being, if I sold the truck, I wanted to be able to sell it as a tow vehicle without going through the hassle of yanking the cam. It had to retain the stock powerband (i.e. 700-6000 RPM's), and the cam I have does that. I did plenty of research and talked with lots of people before I made any of my mod decisions. To this day I only regret one of the mods - the 4.10 gear swap. I got 2-4 mpg more with the 3.73's, and with the 3.73's there was much more gear available at speed (they're 'longer'). I was getting 19 MPG on the freeway and now I get 15-16 if I'm lucky. That few extra rpm's makes all the difference in the world. Sorry about the hijack Ben Link to comment Share on other sites More sharing options...
