I am trying to finish up my engine build and have a question about pushrods. I had read in previous posts on the topic of pushrod size to get 3/8" diameter rods if you have the room for them. It looked like I did so earlier this year I ordered a set from Trend. I've got them all installed at this point but haven't run the engine yet. I was just looking through some paperwork I have on the rocker arms I bought (Comp) for some info on something else and I happened to see that it says to use 5/16" pushrods. Somehow I missed seeing this before. My question is, are the 3/8" going to be O.K. or am I either going to have to get 5/16" rods or perhaps change the adjusters on the rocker arms to accommodate the 3/8 rods? Or, will the existing adjusters work O.K. with the 3/8" rods?
