Lifters

**bigrondownhiller** · 05-11-2009, 02:56 PM

I have a lifter that I think is partially collapsed. What lifters have people used?

**67rsss** · 05-11-2009, 03:16 PM

We are using LS7 lifters.

If you buy new LS1 lifters, you get the new LS7 lifters. Same thing. Some people with extra cash are running the "caddy" lifters. They are pricey, but I have never heard any bad from them. The stock/LS7 lifters will be fine for most applications.

Do those fit the Lt1?

**67rsss** · 05-11-2009, 06:18 PM

I do not believe you can use the LS1 lifter in an LT1. Sorry I hadn't noted that you are running a 96, but your question is vague...

Yea, didnt see the LT1. Cant say, Because I dont know.

someone told me if you swap lifters you have to swap the cam because of wear pattern. any truth in this?

no i would say its the other way around. if you swap the cam, you should change the lifters

But let's remember, if your upgrading to LS7 lifters you want to order 7.350 pushrods because the LS7 lifter is a little longer than the stockers and you must compensate for the difference.....

But then on the flip side, aftermarket cams are smaller in diameter so it makes up for the longer lifter.

When I did my H/C/I Swap, I measured my pushrod length and it was dead on 7.400". I used a Torquer V.2 Cam and LS7 Lifters.

Oh, Ok. Interesting. I guess it all depends on what lifters, what cam, whether the heads are milled and most importantly measurements. Cool man, sorry to add more info on an older thread, I just looking through some. Merry Christmas to you and your family........

That's strange, me too. And I have .037" milled off my heads with ls7 lifters, Trickflow cam and 7.400 pushrods fit perfect with all rockers 1-11/4 turns to torque

I have the exact same set-up but with 64 CC heads and 7.400" worked for me also

Oh yeah...forgot to mention that my heads are milled to 60cc...guess that plays a part in it as well

I am building a 383 LT1 right now and I am using LE2 heads. The LS7 lifter is what Lloyd told me to use and seems to be the norm. If you change anything in your valve train you should always take the time to buy a $15 pushrod length checker and check them. $15 and an hour will save you the money in the long run. The only time it is safe to take the chance is if you have the exact specs for everything in your motor and you replace something with the exact same part you originally put in it and know exactly why it failed. A little extra time double checking will always be worth it.
