I had a shop install tsp cam and tune my stock lsa engine swap, It seems to be more noisy valve train then it was before especially at 2k to 2500 rpm's. I am upgrading to che trunnions
and noticed the pushrods they installed are 7.375, double checked and got about 3/4 turn after zero lash and thought maybe it should have a bit longer pushrods installed, I installed 1 7.400 and have around 1 full turn after zero lash which I think would be within spec and possibly quiet it up some.
My main question is if I go with the 7.400 pushrods will that effect my current tune? will it need to be retuned?
