Re: Upgrading a stock 400sb

You should use the springs recommended by Lunati. Their website doesn't seem very user friendly for fins=ding the recommended components. According to an old cataloge I have the correct springs should be #73943 and retainers #75704. The locks are #77003. You can also buy what they call a valvetrain kit, which includes everything but the cam. That is under #73943K1LUN. I would suggest contacting Lunati Tech dept to verify those numbers.

As for the pushrods. To be absolutely correct, the length should be checked once the cam, lifters, springs and retainers are installed.

Is there any reason to also replace the pushrods? My existing ones appear fine, although I haven't measured them yet. But new ones seem cheap.
