This weekend, finally got the 500" "B" stroker engine running, but had a problem. The engine was hard to crank over, but finally got it started and running at about 1,000 - 2,000 rpm, after a few minutes the engine stopped dead, like something broke/seized  Let the engine cool a bit, and pulled a valve cover to view the rocker arms in case the cam broke. Went to bump the engine over and now it cranked much easier. All the rocker arms were operating too, so I think the problem may have been the transmission? Put the valve covers back on, and started the engine, which now fired up really easy because the starter cranked faster. Engine sounds ok, even though a bit rattley because the valve lash is on the large side. I tried putting the 727 in gear and nothing happened, so I guess the something in the trans broke?  I figure it is the pump or converter. I re-used my old converter and installed the new max-lug gears in the pump, but it may be that I did not get the converter installed correctly before bolting everything up? Anyhow, I will pull the trans this weekend and see what broke. Anyhow, I guess it is an excuse to get a higher stall converter  On a side note, the new 130 Amp Denso alternator seems to work great!

If I had to take a guees I'ld say the conv was not engaged fully on the pump tangs and then they broke.

Yeah, these things don't never happen in Nov. Always just before the season starts or just before a big race you had planed for months.
When you put the convertor in this time, when you think it can't go in any more, put in some more. Once you get it to go in some more, it needs to go in some more.
Once the engine and trans are bolted, you should be able to pull the TC towards the flex plate and it should spin freely before putting bolts in.
Good luck with it, Brian

Yep, Front pump. I messed up getting the converter aligned with the pump gear lugs I guess. The pump ground a nice notch in the stator support.
I just ordered up a whole new race pump, manual valve body and deep trans pan from Cope racing.
I am thinking of getting a new converter too, or at least have my current unit rebuilt. I just need to get this thing back together. Racing starts next month, and I will be out of town for two weeks for business.
glad you found the problem. we wanna see it run too! Should be interesting to see how the Vics compare to the BSs.

You could pull a tranny line to see if its pumping........
For future reference, instead of cracking a line to see if it's pumping fluid, just check the fluid level with the engine off, then start it and recheck.......If it's pumping, the fluid level will drop.....

Sometimes that converter drops into the pump real easy. Sometimes it doesn't want to align everything (converter stator, turbine, pump lugs, etc). Turn and retry, retry, retry, then it just drops in for no reason.
After making sure the converter is all the way into the trans, I put a wrench across it to hold it while I install the trans in the car. This stops the converter from falling out and losing alignment. As I recall, a 7/16" combination wrench with the box end bolted to the lower dust shield hole and the open end against the converter does the trick. After the trans is in the car, remove the wrench and install the converter to flex plate bolts.

 I learned a new trick today.  Now if I can only remember it when the time comes.  Hopefully in a couple of weeks!

max-lug pump gear the hard way  here is my story. When I got the max lug gears for the pump, they have no instructions and I installed the gear with the beveled and angled pump tangs towards the converter. This installation was wrong, and because of the bevel/angled tangs, the converter will sit further back, that is why I thought the converter was installed all the way. Anyhow, I got a new pump from Cope which comes with the max lug gears. Installed it and fought with trying to get the converter installed for several hours. I pulled the pump several times checking that the converter fit the input and stator splines, then the threads in the case started to pull, so I heli-coiled the holes for the pump housing. I finally pulled the max lug gear out of the pump and closely inspected it, and it has a really sharp machined lip on the inner front of the gear, that the converter must have been hitting. I took my dremel with a small grinding stone and put a slight chamfer around the machined lip, so the converter would not carch the sharp edge. Put the pump back together and the converter finally dropped fully into place  Anyhow, I hope to get the trans back into the car today, but need my sleep now..
