7.5" pushrod in a stock motor Tried a search and only found info on shorter than stock pushrods. One drunken night i ordered some new pushords since my stock ones were fine 
. But it wasnt till they got here i realized that they were 7.5" and not 7.4". I was just gonna resell them and get some 7.4" but a buddie says that the 7.5" will work fine, it will just give it a little more preload and quiet it down a bit. Its a stock motor for now, but possibly a cam going in depending on how this speeding ticket goes 
. Question is am i right for not wanting to put the longer pushrods in or is he for saying it will be fine?

Too long for stock cam and rockers. Those would be good with an aftermarket cam and some Yella Terra Ultralight rockers (with the .050" shim installed).
