power package

It's a good package. You will still need pushrods, rocker arms and carburetor.

You say you don't know too much about working on cars. Is the plan to do it to an engine currently in the car?

Get yourself a few small bock Mopar engine build books and go for it. Take your time and triple check everything. Is there a friend that could help you? FABO members could help but sometimes it is challenging trying to help over the web.

The other option is purchasing a Blueprint crate engine that's you could drop right in. You get a great warranty!
