Default Re: Sbc pushrod question

I wouldn't think you would have any problem at all running a good quality 5/16 pushrods with that spring pressure. I ran them on my super stock engines for years with much higher pressure with no failures. Just got some 7/16 for the engine I am puting in my car. It will be interesting to see if there is any difference from the 3/8 that I have been running. I have mostly used comp pushrods in the past.
