Pushrod recommendation?

[omillan99]

Hello everyone, I'm swapping in a 280h Comp Cam into my 400 SBC. I have 1.5 Crane Silver Roller Rocker arms and will be adding in new springs as well. Not sure if this matters but the motor is bored .030 over. How important would it be to get different sized pushrods? Does it make a world of difference?

diameter of the pushrods isn't a huge deal but having the right length of pushrods is. Of course, any aftermarket pushrod is going to be superior (in general) to stock push rods. But always determine the proper length before ordering or you'll probably be ordering twice.. I've always used comp for valvetrain components with good luck. This below thread has some good information from guys on here in respects to valvetrain issues and how to correct them. might be worth a read through.
