Watched you go down the track yesterday....I was up with Wafflebatter (Doug with the roadster) 
Attendance was very low yestarday....Sorry I didn't see you their. Stop over next time...I was kinda still hurting from surgey earlier in the week, and was just off a little....Cut a .500 light in first time trial though, followed by a couple of .470's.
Only to break out in first round with a 6.15...on a 6.16 dial when it rain a pair of 6.17's in time trials. I would have hit the brakes, but I got stuck in the left and it has the big bump at the end. I have to clear that before hitting the brakes hard. Oh well... Nothing broke, so it was a good day.

Mine is an RB block. 1977 casting  It has a little more in it but I don't run the car on the ragged edge. I'd rather keep a little off the edge for reliability. It Is a stock block lol my roller is under .700 I also have a tall fill in it and its a 541 since I'm .055 over. No girdle, stock caps with ARP studs. It's 440 source crank and pistons, I went with aluminum rods. And had it balanced locally.

What do you keep your rpm,s limited and whats the comp? Nice numbers,
Launch at 2100 and shift at 6400...This would be an RB block and it would have a girdle....Current engine on pump gas is putting out right around 730...with the small carburator, and OOTB heads.

I built one 4.5" sroke 440 a few years back for a egular street car. t had homeportd RPM heads, team G intake and a Scotto Brown specced mech roller cam. Worked great and made hue torque, the stock suspension 3600+ lbs car with 3.23 gears, powerglide and 275 M/T ET radial streets run 10.4 in the 1/4. For making power at highter rpm levels bigger port heads are a must!

If your talking about using a 4.500 stroke crank in a stock 440 block and race it when do you expect that grenade to explode?  I wouldn't put that large of a load on the 440 main webs, even with a "girdle" and block filler   Remember the designed strength of the B and RB type blocks is in the oil pan rail supports and block skirt, the main webs are not intended or designed to hold much above 700 HP. Sticking a set of main studs and using the oil pan bolts to hold a girdle on the bottom is not my idea of a good design, more like a poor bandiad
Save your money and buy a good block to start with
Well , i do not run that stroker but I know of 2 that run very well deep into 9,30 with
410 geared cars , 3000# with pro comp full port max wedge heads,,
have been together for several years with just normal issues in refreshing after 2 years of campaining
How ever,,
I have seen those same cars run 9.40 with 500 stroked motors and stock out of
the box RPM heads
Finding the right combo , right mix of parts
Being able to tune a combo, tires gear converter
Is an age ole racers search as much as the fountain of

I wouldn't plan a 4.5 stroke in a 440 block for anything beyond about 600 hp, and then only if I had a very light rotating assembly and / or a center weighted crank to help relieve stress on the bottom end combined with small port heads....
At that point, why bother with the long stroke if you're not going after a big HP number? Get a Megablock or other aftermarket block, let it eat, and sleep soundly.
The reasons are budget, what's on hand and the torque range desired.

If you are over 700 hp now, then you won't build any less on the next one, right? I would sell the stock block and go with a better one. I know that is not cheap, but when you figure the cost of a broken engine, and most likely a lost weekend and down time, and it gets a lot cheaper! On top of that, you would have options of a bigger bore. That almost always helps hp. Also You could buy the after market block, have everything but the bore and hone done to leave options open, and it wouldn't take long to put another together.

The thing about a high HP stock block motor, is that you NEVER KNOW. You are using a 30-40 year old block that may be good or not, but was never intended to make more than about 600HP in any configuration. Its a crap shoot at best.
Just because so and so has a motor that has lasted fine is totally irrelevant. That's not your motor. Now, could you break a GOOD block........sure you could but the percentages go WAY down.
A high HP stock block may last 1000 runs, 100 runs or 10 runs........you just don't know. I have in the past had stock block motors that made over 1000hp on nitrous. Would I build that now??...............hell no, because I know it is a bomb waiting to go off and will most likely ruin everything when it does. I understand a budget, but what is cheaper, a block...........or a block, crank, rods, pistons, cam and potentially heads.
A girdle or any of that other crap you bolt on the bottom of one is NOT a fix, it is simply a weak bandaid for thinly cast main webs. It might help, but most likely not. So and so having a motor with a girdle that has lasted is not a sound argument, because you don't KNOW if it would be broken without it. I never ran one. I chose to run alum rods and alum caps to absorb some shock( which is what breaks blocks).
Bottom line...........stock block is a crap shoot. Proceed at your own risk
