general Ls6 lifter cup question Hello guys,
Im new to LS engine, but learning as i go, my plan's are to build a LS6 for my 67 camaro in the future as now im doing a frame off resto mod.. my question is this, I can buy a LS block from summit fully machined, but where do i find the lifter cups? Do i need to run lifter cups? sorry this may seem a no brainer for some, but im new to LS engine, but love the idea for a LS engine for my camaro..
thanks
Jon

All the vendors lined up on the right selling engine parts should have them about $20 a set. Consider them as gaskets if the heads come off change them.
Check them out there are some good prices on short blocks too.

That's what i'm doing too. After seeing what machine work will cost, it's just easier and almost cheaper to drive to summit to pick up a ready to go block. After i use the 5.3 block for mock-up/fitment, i can haul it to the scrap yard.

most defantly agree... summit blocks are $679 ready for assembly and fully machined included line hone on the mains... yes buying a junkyard block or complete motor for $250-$500 then having machine work done, another $600 well in it over a grand already... summit blocks way to go if you plan on a stroker build or replacing stock internals.. my plans are to build a 408 single or twin turbo.. been doing some research for a while... its more than just buying the parts and scewing them together..im a numbers guy so i like to get into fine detail on certain things..

What about the bearing clearances...are those not "fine details"?
Remember, you get what you pay for.
If you're planning on a big stroker build, with turbos and what not, I'm going to strongly suggest you not get a "ready to assemble" block and do things the right way.

With any engine assembly...the builder needs to check clearances. Block doesn't matter. Simple economics does apply here, with greater production comes decreased production cost. Summit can sell the blocks cheaper than the local machine shop is because it's done in mass production.

Verdad Gallardo Unfortunately, you don't understand. You don't just drop off your block and have it machined. All clearances need to be set during the machining process. You can't do that with the summit block. You just fork over the dough and hope everything falls into place. Because if it doesn't, you're off to the machine shop anyways.

I might use a summit block for a stock rebuild, but not for a performance application where one thousandth off could mean 25k down the drain.

what do you think that means when i say " its more than just screwing one together"?? i means you check everthing including bearing clearences and other details, yes it easy if you know what your doing.. if you have not clue how to assemble an engine then yes things may get scary for a first timer
The point of the summit block is to avoid a trip to the machine shop right?
Ok...
Now...you can check bearing clearances and the hundreds of other things on that block until you're blue in the face, but what makes you think they will all fall into place on the first shot?
A good machine shop will require all pistons, rings, bearings and other components before they will even begin machining a block, so tell me how summit does it without?

oh i understand what your getting, and yes one question i do have with the summit block is piston to wall clearence, they differ from hypers to forged, so haveing a cylinder already bored without pistons is questionable , just figureing that a block thats pretty much preprept may save a few bucks, but yeah it could cost you more if you had to take block to shop again.. not trying to argrue here, i just thought it maybe a more ecnomical way to go, but maybe not in the long run
I'm just trying to save you time, money and headaches. It could be cheaper, hell everything could go together perfect on the first shot, but what are the chances of that? Me, being a machinest and seeing how things being off by .001 or so can totally ruin an engine.
In my opinion, if they sold that block with the line hone already done to factory spec and maybe a .020 unfinished over bore and virgin deck (or just decked for flat) it might be a better choice.
Since it already has finished bores and decks, who knows how the piston to wall will come out, and who knows what the exact deck height is. And what is the ra of the deck? Different head gaskets require different roughness averages to seal properly.
There is just too many questionable variables for it to be appealing to start a high dollar, high performance build on.
Not trying to argue or be a dick, I just don't want someone to fall into what looks like a good deal, only to find out it has to under go everything a junk yard block would have to.
Or worse, buy into summit's sales pitch and just throw it together to have it grenade itself because piston to wall was too tight.

See, i there are posts all the time that state use a good machinist. I found one, somewhat local, that wanted $600 to bore from 5.3 to 5.7 with hot tank and new cam bearings, decking would be an additional $200. That seemed kinda high to me, thats why i was looking into a ready to go block. TSP has a 6.0 new block, but shipping would be high from Texas to Ohio. The Summit block seemed like a viable option for $675, plus i can drive 10 minutes to pick it up.
