I'm going to be doing a cam swap and wanted to know if anybody has some lifters for sale.

Thanx in advance

 

Talk to James @ Mopac. I got mine for less than $300 a year ago and since then, their prices have gone down because of the strong Canadian dollar.

I got mine for $315 with tax.

 

Dang one of thiese days I am gonna have to get some of those expensive as hell lifters!

Till then I will keep Spining my stock units to 7,000 RPM!

 

Way to compare Anti pump up lifters to regular bleed lifters. You can't run stockers at 0 lash without valvetrain noise & beating up your valvetrain, & if you run them to 7k rpm you will have the stockers bleeding so you'd see better lifter numbers at those rpm's with comp r's.

BTW, I'd rather get new lifters with a new cam anyways & why not go with Comp-r's since they are only about $10 more then regulars.

Matt.

 

geez Ellis, you'd think after buying those fancy shamcy heads and intake you'd have budgeted for some decent lifters j/k

Anyways...I'm guessing the advantage of these CC R lifters is that they try to mimic a solid lifter in its actions. Meaning they are less likely to bleed and transfer the energy from the cam faster than a regular design at higher RPM's. Am I right???

I'm also told that they are harder to adjust for the first time use...can anyone explain this?

I'd say buy these bling bling lifters...

SO Bunker you ready to run heads up?

All your fancy stuff against my rock bottom priced crap?

I have been running thiese lifters for 56K MILES.

I know you guys are all the experts but when you going to whoop my ***!

 

Ellis, thats most unprofessional, the point is your stock lifters will bleed off at high rpm..


Andy, you are correct but the part where they transfer the energy faster, what acctually happens when a lifter bleeds off is you loose lift & retard your valve train timing.

 

LMFAO! What is UNprofesional giving infomation other then what you are giving? I choose to prove a ponit. Wasting Money is un-needed. The truth is the stock lifter is fine for the limits of the Stock computer. The Comp unit merly uses up money that could be properly used in other places.

WHAT it comes down to is IF you choose the PROPER compontents your ENTIRE valve train will live longer

It is the package not one part. Telling some one That XX part will make there car rev to 7,000 and the other won't with out knowing what you are really talking about is a bad thing and I will call you on the carpet every time.


BTW It has been proven Lifter pump up is caused by not using enough spring pressure to control the valve train

 

Well at high RPM with big springs you'll start bleeding those things, its peice of mind to go with new lifters especially with a new cam in there. Springs over 420 in/pounds require a stiff lifter like the Comp R. BTW, for your cam you dont need much spring pressure I think they recommend about 110 on the seat which i think is pretty low, then agian it is a soft ramp cam. Plus with spring pressures that low they antiscipate valve float at 6800, to be on the safe side I'd run more spring pressure, thats when a good set of lifters comes in handy.
