Just picked up this 409 marine engine today

[entourageguy]

This has been sitting in a boathouse in an old wooden boat for 30 years. The boat had pretty well rotted away and the guy I got it from had to hire a crane to reach down to the boathouse and lift it out. It's a 656 block with 333 heads a 3830831 intake for a 340 hp 409. It has a rochester carb with tag 7023183 which shows as a mercury marine. The dist is a 1110637 which is also marine. The block front pass side has TIII88R stamped on it. The dist has packard plug wires with date of 4-0-64 on them.

Way to go!
I think you should probably think about a new set of wires.

[Don Jacks]

Great going.................It's STROKER time!

 

[entourageguy]

don't know which way to go now. Leaning towards a mild build for the 409 and selling the 655 348 block and cranks.

 

[yellow wagon]

oh yea build the 409 for sure. Sell off the 348 parts

 

[entourageguy]

out with the old!
gotta love the sour cream containers.

 

[Don Jacks]

Brian,have you pulled a head to determine wheather it's a truck block or not?

 

[entourageguy]

I hope to pull a head this week.

 

[entourageguy]

Pulled one head and it has a notch in it. Also had copper head gaskets in it. The upper cylinders are a little on the rusty side.

 

[NASTY 409]

Do you have any pictures of the boat the 409 came out of? What year and make was it ? thanks Nasty

 

[entourageguy]

I'll have to talk to the guy I got it from and see if he has any pictures.

 

[entourageguy]

called the guy and no pictures. But he said it was a chriscraft that the engine came out of.

 

[entourageguy]

3839806 cam shaft I think original cap 571594 on the distributor.

Took the 333 heads in to get started on the build. They were a little rusty and pitted in the combustion area so we used another pair I had. Going with 1.7 rollers and screw in studs. The eliminators for the exhaust rotators do not drop over the valve stem tower and will have to be opened up. is this normal? Finished up stripping down the block and getting the pistons out. It's at the builders now. Just waiting to see what size the cylinders clean up at so I can order pistons. I've got my cam and springs from Aubrey.

Ronnie should know. maybe the valve stems get turned down for seal fitment?

 

[Ronnie Russell]

BBC rotator eliminators need the inside diamiter increased. Let your machine shop take care of it. Showcars should have made note of that to its customers.

 

[entourageguy]

should the spring be sitting to the outside of the raised edge on the eliminators?

 

[entourageguy]

Well have not posted much as I'm busy collecting parts. Pistons are on order thru Aubrey any day now. I've got my cam and con rods, roller rockers as well as new msd dist and other parts sitting on a shelf or at the rebuilders. 333 heads have been gone over with 2.065 intake and 1.725 ex valves. Block cleaned up well and is final bored 4.350". New edelbrock 2x4 intake ( sorry Aubrey) and a set of Dougs tri-y headers.
. I've installed a dual master and discs for the front. Broke down and am putting in a 600 power box as well.
