ok so i got installed a g5x3 114 cam on my camaro 2002, which has the 243's heads, those heads were milled 10mm, thats what i was told by my uncle who went and got the job done with a friend of his.

now i want to replace lifters and pushrods, im going to get the LS7 lifters, but i wasnt sure how to know what pushrod size to get, any help would be greatly appreciated.

thx

.07 milled off equals 1 cc

Stock 243 are around 64-65 cc's.

So 10mm doesnt sound right?

The heads should have had Their CC measured first, then a test mill of .07 to make sure it's cutting correctly. then finish it to the desired thickness...

anyway pushrods are the last thing you should buy, get your lifters, then get a pushrod checker (20$ off one of the vendors to the right )

then you'll know exactly with no guessing.

10 mm is too much bro ,, you dont think he meant .010 thous of an inch..

10mm is .393 thous of an inch thts too dam much,,

c5z16z

you mean .007 is about 1 cc not .070 thous
,,

and yes wht he said get your pushrods last take in consideration the gasket and how much more you will be milling and get the pushrod checker

yea maybe it was .01 haha, cuz i do remember he said it wasnt that much, cuz doing more would have resulted in more changes.

i will ask tomorrow to make sure, but lets say it was .01 what would be a good pushrod size, using ls7 lifters, im not sure but a friend of mine said that the ls7 lifter are slightly longer?

IMO,

I would get the Comp Cams pushrod length checker. That's the one I have and from what I read its easier to use than some of the other ones.
