brad penn is good til 280*. my 360 block is short filled and I see 250* often. no oil cooler.
Not to resurrect an old thread, but Dave, what do you call a short fill on your block?
I went to go pour fill in my block today, was going to do to the bottom the freeze plugs, till I got there, popped out the freeze plugs and realized there really is no material to fill below them.
It's looking like im going to be doing to the bottom of the water pump bolt holes just below the water pump ports...probably going to end up with an oil temp gauge too now (another damn gauge to worry about).

If you have any concrete left over after you are finished I could use some. I have a low spot in my yard that I would like to fill in. 
LOL...I have a whole bag, so I should have some I can send your way..I hear it works good to filling in break throughs in the victor manifold ports

My Stock Block 70 360 Build was sonic checked,1/2 filled before machining with torque plates on and filled one side at a time allowing time to cure, turned the block to allow level filling. my builder/ machinist also installed pro-gram steel 2 bolt caps, he didn't like the lack of material in the area where the outer cap bolts would be drilled, and said girdles are a band aid.
Its a 59 deg W9 build, only bored .030" over with 4.125" stroke.
After all the work done to this block I should have bought an 48 Deg R3.
What are you calling a half fill?
I always assumed a half fill was up to the bottom of the core plugs, as that is what most chevy and ford guys call it...but on the small blocks, there really is nothing to fill under the freeze plugs...Are you going halfway between the bottom and the water pump ports? or right up to the bottom of the ports?
This is really costing me nothing...my brother already has the concrete, and my block was already machined last year...just a matter of me pouring it

It's interesting to note that the cooling system also acts as a hydraulic pressure vessel and also acts to a large degree as a fluid dampener around the cylinder walls. A lot of people tend to overlook how effective a properly functioning cooling system is/can be. Hard block diminishes this ability to some extent but conversely reinforces the mass around the crankshaft webbing.
on the street there tends to be a lot of wasted momentum in terms of what percentage of developed power actually is applied to load and gets to the ground. the more well-scienced your car hooks the more Percentage of power (load) you subject the block to.
If you hard block it I would run an oil cooler just as added protection against getting stuck in traffic in the middle of summer which is about the most taxing heat/thermal expansion a street motor is going to see. Not so much what heat it generates drag racing at WOT (because there is a long anticipated cool down period) but more a possible inability to dissipate heat under extreme and prolonged conditions.
Hey Wize, thanks for the info! I am seriously considering adding a cooler and remote filter as well....oh and an oil temp gauge....they aren't kidding when they say speed costs money...I liked the 12 second 87 octane days my car saw LOL

The half fill on my block was up to the top of the core plugs.
but it is not a street motor, so no cooling issues. unless you count backing it out of the trailer for a local cruse night.
honestly if its already machined and a street engine I wouldn't bother.
Its street strip, should be making a little over 500 on the motor, and close 700 on spray...if im going to run on borrowed time, I want to maximize that time lol

My 408 is studded, and has a Hughes girdle, I liked the fact that the girdle ties everything as 1 piece, I dont like the fact that the splade 4 bolt caps cut into a already thin webbing unless your running an R block. Matt I personally think that the hard block isnt worth the time for you at this level. Your gonna be time/money ahead if you just spend the time to studd and gordle/4 bolt the bottom end, and the bores on that block should be plenty stout for that power level. Mine is a 77 360 thats .030 over, forged guts, and studs where needed. I know a few guys like hard block, I personally dont care for it from the standpoint of heat transfer into the cylinders, and what the water is accually there for.  Who knows though, Im by no means anything close to what Mr P, Brian, or other builders on here know so I may have just waisted a page here.....

friend of mine has a similar engine to mine same engine builder but in a 3200 pound Cuda, Indy Heads with an early factory 360 block, no fill, but good caps and ARP studs he has run hundreds of passes in the 9.50s and sprayed it to run low 9s if he took some weight out of it and or sprayed another 100 HP it would go 8.90s
Damn that is getting it done! Especially for a stock block setup...what made him not fill it, yet you did yours, and from the same builder

Hey man, opinions are like a-holes, everyone has one, including on this topic... I always appreciate insight and experience from others when trying to make a decision 
It seems everyone I talk to has a different opinion on this (what a surprise LOL), so im going to have decide what I feel most comfortable with and go from there.
I just don't want to have this motor apart again because I break something when spraying it...I need something to stay together for atleast a couple of seasons instead of this every year something new crap lol
