Quick valve lash questions...

FWIW I used the Carter muscle car pump on my 360 and it stays below 5.

I used one of them for a 400 and that thing would put out over 10.
Yeah.. i'm using a $15 amazon special.. so i don't have high hopes for it to be correct :) I have my original bolt together carter from '62 but i don't think it would be a good idea to run. I always used to use carters but read that new ones are **** so didn't wanna spend premium on one
