lifter , timing chain, oil pump hey guys it wont be long before i do the heads/cam swap in my car and i have a couple questions and was looking for input
i was going to replace the lifters, timing set, and oil pump while im there......
ive read alot of people use ls7 lifters, why????? why not use stock ls1 lifters.....please explain....... also what would u guys use?
next is the timing set........
ive heard alot of ls2 timing sets... same thing.... why is that better and is that what yall use?
last
which oil pump to use......
would a brand new stock ls1 pump not be sufficient...... do the ls1's need more oil pressure with a cam installed?
i was gonna get a texas speed head/cam package should i just get the ported ls6 pump they sell for 150????????
thanks guys

Since you are in there you might as well replace the lifters. LS7 lifters are a cheap replacement and have proven themselves in many different setups.
An LS2 chain is an excellent upgrade. It is cheap and stronger than the LS1 timing chain. You can tell the difference between the two if you hold them next to each other.
I personally bought a melling high volume oil pump. You can put in a different spring to bump the pressure up, but my pressure is fine currently anyway. Melling is a brand that has been around for years and has an excellent reputation.

We have the lifters as a set for $122
the LS2 chain for about 38
as for the oil pump, i would personally not go with a high volume pump. high pressure is ok. a stock LS6 pump (they are all the same now just like the LS7 lifters, but the name sticks) will work just fine. if you want something else then we have the ported LS6 pump for $150 or the melling high pressure 10295 for like $120

great price bump!
and do you have more details on the ls2 chain?does it include gears and sprockets?
n do you have a website?
also i got an impala with ls4 would this be an upgrade cause i think it already comes with a high volume oil pump from the factory due to the DOD, but as far as the lifter and chain go it should still be an upgrade?

the lifters work very well. also the ls2 chain is exactly that. just the chain. you can use your stock gears with it.

good info and i completly understand, but i mean not much oil stays into the oil pump anyways since there is not much room, and if anything more oil can be added to the oil pan to keep it at the optimum level right? after installing my high volume pump my guage is showing no less then 58 psi at hot idle. i dont know if that normal or not? its stock psi spring with a .100 shim. sorry for the thread hijack

well the volume is normally determined by the surface area of the rotors inside the pump. not pressure. it is not the amount of oil that stays in the pump, it is the amount of oil that is moved by the pump per revolution. i would not suggest more oil in the pan though either. its a bandaid to clear up a problem that can still be there.

you also need to know that the LS7 lifters are a different height than standard ones, research it and you will see, Be absolutely sure to measure your pushrod length. If dealing with TSP they are super guys and they can get you really close on the length, but to be absolutely sure you need to measure.

The lifter itself is the same height but the cup on where the PR sits is higher in the LS7 style lifter.

My question to you is why not? I have the Melling 10296 and cold I am pushing 55psi of oil. Better than an LS6 ported and better than the 10295. Ask any one who has invested the extra money in a 296 and they will tell you like I will tell you its a very good investment. I have been running the same pump through two H/C packages and I have had no issues at all on a stock cube LS1.

Well, faith well placed is one thing. Can you honestly say your engine needs the extra fluid flow from a high volume pump? Unless your builder uses the excuse "we build it on the loose side so use a high volume pump", which is a topic for another day, then there is no reason for it as far as i have seen. Esp the gm DOD pump.
