Hey Robert,
got some pix of that 304 that was in a flood. Actually doesn't look as bad as I thought it would at this point w/the exception of that 1 cylinder.



check them out.

From the way you decribed the flood 304 you are probably in good shape. I had to cancel going down to el cajon a couple of weeks ago due to family matters.

Anyhoo hope you can fix the link as we looooovvvve pictures.
 
Ok, got the pix up. I guess I didn't make them available to everyone, just me...

So the engine has been sitting for about 14 years. Went thru a flood 6 years ago and I never touched it.
The tranny was attached so I had to spin it over to unbolt the torque converter to put it on the stand.
I took the plugs out and spun it w/an 8" drive.

Out of the pan came maybe a gallon of crystal clear water then the sludge and vaseline-like stuff came out. Nice green coolant came out the pass. Side water jacket drain plug. There was a hard crust covering maybe 60% of the water jacket drain plug on the driver side. I poked it out w/my scratch awl.

The cylinders are smooth and look good, nothing has any rust on it except for that one cyclinder (#7).

The block is all scaly, rusty on the outside so I'd like to sand blast it.
I was going to remove the pistons, con-rods but leave the crank and cam in place when I do it.

So the eventual plan is to take it to a machine shop and bore it 0.060" over to match my pistons and use my other crank/con-rods.
I will need a new cam and bearings too.
I have the main bearings that came out my other motor w/maybe 50 miles on them.
I dropped #3 bearing while taking it out and it has a small dent in it. It is fuzzy but it is above my thumb on the outside edge. It is the 3rd from last picture on the link. It has the following markings on the back side:
2413 cp
f/m
u std
06 10
2253a

I'm hoping they are the same size as stock so I can re-use them or am I being stupid?

It also has 9 stand rockers where my redone heads have the 5-stand. Both rocker sets are stamped. Is it worth re-doing the 9-stand assemblies some day?
 
That block should clean up fine.
The bearing number you posted is standard. Don't know if that helps.

If you do plan on sand blasting it, loosely reassemble it or tape it up before you do. Even though you can clean it out the possibility of sand staying in a nook or cranny is real. Don't want that. I'd set the heads back on it and screw the pan etc on then blast away. .
 
Hi Robert,
did we get far enough to pick a camshaft?
I'm having the block picked up tomorrow to go to that diesel machine shop I told you about w/my 0.060" over pistons.
That same guy will help me out but we are doing the assembly in my shop in front of me.
My Scout has 3:73s and 33" mt/rs w/a 727. Gonna run the stock crappy 2210 carb. The current cam is a schneider 256-2h grind.
I'm gonna use it to commute and maybe pull a 20' boat twice a year about 25 miles each way on secondary roads.
When the truck was running good it always felt "squishy" off the line never crisp. I felt 400 horse power away from breaking the tires loose.
I'd like to have nice bottom end power. Should I do anything about a torque converter?
Any recommendations?
My lifters have maybe 50 miles on them from. Should I replace those w/the new cam?

I'm gonna start to make a wish list on Jeff's store for a cam, cam bearings and a gasket kit.

Id go with the smallest isky or comp that Jeff sells. The trick is to degree it and make sure it is advanced 4* from straight up.

As always a new cam = new lfters. Can they live? Yes but yes they can fail. Why risk it at this point?

Leave the tc stock. Nothing you can do will help do anything but make lots of heat
 
Hey Robert,
is this the one we are talking about?

Part #: isky-190125-26

performance camshaft. Great low end torque. Decent vacuum at idle. Iho north's personal favorite. Fits all 266,304, 345, and 392 v-8 engines.
Rpm range: 1800-5000
valve lift is calculated with zero lash and rocker ratio of 1.6
intake timing duration: 256 deg.
Open: 18 before tdc
close: 58 after bdc
cam lift: .281"
valve lift: .450"
exhaust timing duration: 262 deg.
Open: 61 before bdc
close: 21 after tdc
cam lift: .290"
valve lift: .465"
lobe center: 110 deg.
Overlap: 39 deg.
Cam advance: 0 deg.
The above timing is checked at .020 (open) lifter rise .020 (close)
the following timing is taken at .050" lifter rise and gives a more accurate determination of camshaft position.
Intake duration: 202 deg.
Open: -9 before tdc
close: 31 after bdc
exhaust duration: 208 deg.
Open: 34 before bdc
close: -6 after tdc
