No, not a chevy cam a Small Base Circle, aka SBC.

regardless of cost, a new set of lifters is the right way.

If it was a custom cam shouldn't shawn have told him witch ones to use in the first place or sold it as a kit ? Or was this a case of already having something and using it ?

[dumpycapri85]

Does anyone know at what lift point you have to move to a small base came ? At some point the lift gets high enough to need it correct .

Personally, I don't subscribe to the notion that the cam guy is responsible for everything in relation to the valve train - usually that falls on the engine builder or installer (with the exception of maybe spring pressure recommendations etc). Since his grinder, or who he works for doesn't manufacture lifters - I'd say the kit option isn't going to happen. My guess is he just ordered "solid roller lifters" for a SBF like everyone else does. Also, I don't think it's a lift point that you have to use the different lifters - it's more of how much the base circle was reduced. Unless it's a stroker motor, I'm not sure why there was a RBC cam used in the first place - I'm sure there's some sort of reason.

And, OP, don't take it the wrong way - but if you're inexperienced enough to not problem solve enough with the clues given, you really should have someone else do the work for you, who knows what to look for.

A seasoned tech/installer may NOT have seen THIS problem, but most likely would have gone through the steps to find the problem...They'd also most likely have known is a SBC cam in the first place. (It's VERY obvious to the naked eye). Now, would they have known the lifters were wrong? probably not....


assuming an accurate description of the work done - I don't agree with grinding ANYTHING on the lifter for ANY reason. If the oil is not making it to the top of the lifter because the oil band is not meeting the oiling hole - then you will have future problems because this means that the oil band is dropping out of the bottom of the lifter bore and bleeding pressure off. This WILL burn up the rod bearings in short order after a few WOT passes... go ahead and ask "fast408" about that one, curteosy of Sunset Race Engines.

i do take most of the blame for not knowing as this was my first build ever im learning as i go, its not just me building the car its me, my cousin and father (they having alot more knowledge than me), so what lifters do you recommend for me to use with a small base circle cam?? http://www.summitracing.com/search/P...?Ns=Rank%7cAsc

[dumpycapri85]

I was under the impression that sometimes a grinder will make a cam with so much lift it would not clear the cam bearings on installation unless it was a SBC . I also know that they sometimes do regrinds of other cams to make them larger and you end up with a SBC .

Those are all great lifters, but if it were me - I'd call the manufacturer and make sure they work with small base circle cams. Sometimes, that's not listed in the footnotes.
My personal preference is to use Lunati or possibly Crower - they both come with high regards from Hans. I bought Comp lifters for mine a long time ago, before I knew of thier shortcomings - but allegedly the needle bearings give up and they spread the trunion open, allowing the body to contact the cam lobes... and scrap your cam. I've heard one season, a half season, a few hundred passes etc.. There's a reason you see them at all the swap meets, all the big boys are scared of them and toss them after X amount of usage. I'll be changing mine sooner or later.

That's possible, and something I don't know for sure either way.

yeah these are Lunati's but ill call them and ask them for some that are for SBC's

Damn, that sucks - they are NICE lifters too.


For the records, I'm not giving you a hard time - I just want to see you get this thing done right.

Be sure to check any new lifters you get side by side with the old ones, you should see a definite height difference in the oil band from one lifter to the other.

yeah i know your not giving me a hard time, well i called Lunati and asked them what lifters would work on a SBC cam and the funny thing is that those are the lifters i have.

whoa...

I'd REALLY hate to think that grinding on them is mandatory - did you tell them your problem?

Why does this motor have a reduced base circle anyways? Did Shaun say?
