pulling the motor in the AM.

I am going to check the bottom end and RR the freeze plugs....it will give me a chance to see what's in the motor.
Hopefully nothing is hurt and I can clean it up repaint it as well as put a
new timing cover on it ( the current one leaks a little)

The pump is going to ship to Central Texas Jet-boat for a rebuild.

here's where the questions start.

I have identified most of the internals

it's a 4 bolt with a steel crank, 3521 (that from what I have read online is a good one). slightly domed .30 over pistons / 990 heads and a 3885069 GM intake manifold dated 11-2-65; 
Carb is a 3310-1 - 780 Holly 
 I'll have cam specs in a day or two ..

I am looking for direction on the intake.

I was thinking about selling the current intake and replacing it with something  newer...... I see a lot of mention of Vic Jr's......

opinions?

I ask only since this
manifold is almost 50 years old, and newer ones must have better flow characteristics right?

I like the weiand stealth as well.
A really good performing dual plane.

The bearings looked good, as does everything else.
I've never built an engine, but I'm stoked about doing it.
I now know what I have so far as the components. I'm hoping to sell the intake I have and get a  Wieand Stealth intake and a different cam.

The one I just pulled is a Clay Smith unit; I called them to find out the specs and the girl that answered the phone had me talk to a guy named George....we talked about jetboats ( he said he has one) and what I wanted for my boat, he was very cool and we spoke for about 30 -40 minutes. he told me he used to "race a little" both cars and jetboats and had to stop after he had a bad wreck.....he gave me a recommendation for a little hotter cam and told me to call him back after I had the heads tested and checked the springs.

I didn't realize until after I had hung up and went online and did some reading about Clay Smith cams that it was the owner George Striegal I had spoken to!
 I was surprised at the time he spent with me, he acted like we were old friends.   very cool..... very classy.

 I'm taking the heads and block tomorrow for hot tank, magnaflux, and pressure test.....New freeze plugs etc.

Also to pressure test the heads, check the springs as well. I'll be able to have a fresh motor and after I get the pump back I'm hoping to get it up and running before the end is the season.

I want to thank everyone here for the suggestions and help that has been given. I've learned a lot and appreciate it. Perhaps next year a trip out west will be in order.

George will do you right, he specd out my valve train and cam and it's running pretty good

I'm leaning toward that same intake....
