This should be an easy one, though. Does anyone know who actually manufactured the Kenne-Bell P/N KB10003 "Hi-Rev Hydraulic Lifters"? There are no identifying marks on the box they're packaged in (other than the K-B label with the logo and part number), or on the lifters themselves. I haven't done it yet but, if it will help, I'll measure the length of the lifters, and the depth of the push rod cups. Let me know if you need the info. I plan on using them for with a Lunati 68002 Voodoo cam for the BBB street engine I'm finally getting around to finishing, and knowing the actual manufacturer of the lifter may make it easier to determine that they will be up to the task. Now, before anyone gets too excited about my cam selection, this is a milder grind than the P/N 68003 that has been referenced in a number of discussions in this forum. The engine's also equipped with Edelbrock heads (longer rocker arms). Anyway, back to my question: Who actually manufactured the hi-rev lifters for K-B? As always, thank you all for your assistance over the years.
It may be a long shot, but call Kenne Bell and ask if anybody knows. Tell them you realize they do mostly Ford stuff now, but you have a set of Buick Hi Rev lifters, and would like to know who manufactured the lifters for them. Hopefully one of the people there that were part of the "Buick era" will know.:idea2:
I'll bet it's Speed-Pro, Sealed-power, Federal-mogul (all the same co.) Does it have a snap-ring (circlip) at the top or just a retaiing wire holding the plunger in?
http://www.v8buick.com/attachment.php?attachmentid=224081&d=1333456087[/URL] Those are the retaining wire type. Not meant for super low (0.002 - 0.004") lash, but instead regular (0.030"-0.040") lash. If they are true "hi-rev", they will prob have a disc check valve inside. Easy enough to disassemble and check. Could be the old johnson type. http://www.jeepstrokers.com/forum/viewtopic.php?f=5&t=1262&p=13119 http://www.v8buick.com/showthread.php?246655-New-high-rev-hydraulic-lifter&p=2018577#post2018577 http://www.v8buick.com/attachment.php?attachmentid=224081&d=1333456087
Just my 2 cents, that is a mild street strip cam, 227-233 duration, .521 exhaust lift, it peeks at 5800. Stock hydro. lifters will rev to 6500 with no problems. Lunati also sells a performance lifter for the 455.
The 68002 voodoo a"fast profile" lobe & could be somewhat rpm limited ... I think a set of the Comp Pro Magnum lifters would be a wise choise , my camshaft is a "fast profile" type & before installing the Pro Magnum lifters it would only go to 5100 with power now it will turn 5800 pulls hard . It works for me & they don't make the noise of the Delphi lifters that were on that cam. ick
Yes, even though this grind isn't as aggressive as the 68003 cam that JW dealt with, plus my engine will only experience high RPM runs on the dyno after break-in, I would rather play it safer than "sorry-er". According to Desktop Dyno 5, this cam will produce tons of torque right off idle with my "exhaust limited" set-up (lightly ported Edelbrock heads, TA Shorty headers and street-type exhaust system) and TH200-4R lock-up converter. The engine will hardly ever see RPM greater than 5K but, just in case.....
One time i was told that the high rev description was just a sales gimmic. I would call JW and ask his opinion, i have never heard of any of his engines running a high rev lifters. Most people run the stock type, even TA dosn't sell a high rev lifter. I just dont want to see you waist time trying to look for something that isnt worth the effort. I sure mine are just stock they came with My 113A Postons cam, i run adjustable push rods, and dual springs, 11 to 1 compression, polished and peened stock rods. still running great 10 years later, i can shift at 6000+ all day long, it pulls hard to 6800. Just my 2 cents
Kelly , the "Hi Rev" lifter used higher bleed off rates than a stock lifter & they won't address the problem of rpm limited fast action cams these cams are NOT pumping the lifers up & holding the valves open @ high rpm. Pro Mag lifters keep the plunger in the best postion & that enables the lifter to function with the aggressave cams . The bottom line is it's a win-win no major noise issues & increased rpm range ..... all I will say is I KNOW THEY WORK & several have thousands of miles on them with no problems . I would not think twice .......... ick
My Question is, what lifters are people useing in there Buicks? What lifters do the Buick engine builders reccomend for these cams?
Well, as a result of reviewing ick's "lifter crash" posts: 1 - I will not attempt to use the K-B lifters with the Lunati 68002 cam. 2 - I'll use my K-B lifters with the TA 288-92H cam that I've decided to use instead of the Lunati. The lifter acceleration rates of TA street/strip cams (suitable for my combination) are less aggressive than that of the Lunati. I kind of hate to give up the low-RPM torque that the Lunati provides, but I have it on good authority that the TA will suit my overall needs quite well. After all, my convertible will not be spending any time on the drag strip (no cage), and I've long since outgrown street racing. So, looks like I'll soon be posting an ad to sell my NIB Lunati cam, along with a recommendation to pair it with Pro Magnum lifters, at a great price Actually, if I waited until yesterday to ask this question, I wouldn't have had to post it. How come? ick's post regarding the performance of his car after installing the Pro Magnum lifters clinched it for me. So, thank you ick.
Yep thats what it all boils down to ..... fast profile / you will need to match lifters & componets to allow the cam to preform to it's full potential keeping in mind that every set up may be differant . I think you will be very pleased with the T/A camshaft as for the torque ...it's a Buick I would not worry too much! I would like to thank (NO LIFT) and all the others that helped me to over come this problem , the bottom line is both of these cams will preform very well & in your case if you have the KB. lifters use them , as to the differance in preformance I would have to see a back to back test ,some people claim they have seen preformance gains but they have also said it took more than just the camshaft swap to obtain these gains. There are so many other areas to gain HP & Torque that maybe the cam should just be thought of a a tool to complement the cyl head air flow numbers .... much like JW had said in several posts that camshafts are over emphasized at times . Thanks Mark
Im concerned about your converter, are you running a stall at all? Usually you need at least 2000 stall with a cam that will have a rough idle, it might kick the converter when you are stopped and on the brakes. And as long as you have desent compression you will not lose low end torque. Compression is torque, usually when people run a a cam with lots of overlap without the commpression to back it up, it make for a engine that is a dog out of the hole and never really recovers at higher RPM. I have driven a few chevys that were set up like this, and they flet like you were pulling a trailer. Just my 2 cents
