milled heads .30, What length pushrods
Im hoping someone has milled their heads and knows what the correct pushrod length is im needing, Dont really want to have to buy a length checker and all that....Any help is appreciated
Heads are milled .30 std. deck height. |
Wish I could help...I'm having my 317's milled .030 when I put my LQ9 together, and I bought a pushrod length checker, it was $13 at the time, I think that they're $18 now. If you're in Jersey I'll lend it to you :chug:
What lifters are you using, that makes a difference too...the new LS7 lifters have a taller cup then the original GENIII lifters... |
were on the same page.. here also...
im gonna be running ls7 lifters / guides.. and my 317's are also milled .30 prob still the same 7.4 |
LS7 lifters ported/milled 862's...i dont mind buying a checker just thought i might save some time if someone else already knew.
|
Isn't the ls7 lifters shorter then the ls1 style?? I think so.. I would run the 7.35's in there.. Or get a PR checker... It is good to be dead nuts on, but the hydraulic lifter will surely take up a few thousandths in..
|
Stock pushrods are 7.380". So if you chop .030" off the heads you would require 7.350" pushrods. Regarding the LS7 lifters, I have no experience with those, but I've read they like shorter pushrods than stock.

M_e_a_s_u_r_e!!!
|
The cup in the ls7 lifter is .060 taller then the older ls1 lifter.. :D Also with a .060 preload
|
So it looks like its best to measure, no big deal
