I could have done a search, but many of you guys know this in your sleep. I am planning on getting a 351 maybe this weekend but didn't think of one thing. The 351 had an automatic, my 302 has a manual. Flywheel - is this externally balanced for the engine ? Will the flywheel from the 302 fit the 351 ? If I do this, do I need to get it balanced for this engine ?

What other major issues might I run into during this swap ?

My host truck is a 92 vintage 4 wd and speed density.

Do have a set of GT40 p heads and plan to do a cam, long tubes and duals.

I know I have some reading and research, and will likely go with Conanski's cam suggestion.

 

Yes.
Yes.. but it's the wrong balance so don't use it, you need a 28oz version. The 5.0 used a 50oz imbalance.

 

Ok so I need a 28oz version flywheel, just bolt it on, or does a balancing procedure need to happen with the actual engine I am using ?

 

28oz flywheel and bolt it on and you are good to go.
