 Topic: 400hp 301?
Posted: 04 Oct 2018 at 7:03am |
|
My question isn't on how to make power but at 400 or so horsepower what weak points are going to be an issue with a 301? The bottom end is my main concern but I'm sure other things should be taken into consideration.

Bending connecting rods would be your first concern.

Will the crank still be happy or is it time to get a custom crank made?

We still use a stock 200 crankshaft at 1200 HP. Didn't girdle the main caps until over 800 HP.

Just a side note after rods use a crank drive oil pump and weld the gear rot shaft it Will spin the drive gear on the oil pump shaft.

I knew the rods weren't that great wasn't sure about the crank. Will just the 7080 injector tips be enough or will they need to be reworked?

I believe Max Simpson used to sell hardened rods, but I thought I remembered reading that he wasn't doing it anymore. Anyone have any idea where to buy hardened rods?

7080 injectors (.0148" holes) won't get you the desired 400 HP. I'd guess at least 4 hole x .0200" or bigger. What injection pump are you thinking ???

Probably a Bosch p7100, it'll be pretty easy to get parts for and have more than enough fuel

If I was you and 400hp is all your after rethink that to an A pump not as much grinding and cutting to make it fit.

I'm a machinist so I'd probably make a new front plate if it came to it

Did the 2800 blocks have provisions for piston cooling jets or is that something that would have to be drilled

The maroon 7000 tractor engine in about 1977 had piston cooling, while the older ones didn't. Don't think I've ever seen a 2800/185/ F combine engine drilled for piston cooling, but there could have been. If they did do that, they just used upper main brgs that blocked it off unless the block became a turbocharged 2900 instead.
Not hard to do. I've done 3 or 4 over the years. Hole size is important.

Couldn't find 3/8 banjo torque specs in service manual for the injector lines, anybody have this off the top of their heads?

It's the German standard - goodentight !
I don't know how you would ever get a torque wrench on all of them.

I always Losses and tighten a few 5-6 times like your lapping a valve to seat the sealing washers

What about the nozzle nut on the injector, I'd say it's a bit more particular to a specific torque than a crush washer.

According to the book it’s 20-25ft.-lbs.
