Also, do you know how i can find out what length pushrod i need?

Crane energizers are cheap if you are looking at new but you dont save much.

Push rod length you have to be careful with and I recommend you get lifters and rockers so that you can set it up and then get an adj pushrod or pushrod length checker to check lenth with or you can see if any friends are building motors and use a couple different lengths until one fits right that has the right geometry.

I like crane golds for the money and a 6.702 is a pretty good.......bet.....as to pushrod length but it does vary!!!

As far as lifters I just use stock replacements if you are using a standard hyd roller tappet cam.

Crane sells them for about 100 bucks as well.
