Stall too loose??

Fired up my 515 a-headed motor, did a stall check on the transbrake.........7200...

This is an Ultimate Converter that was built for a little larger CI BBF a-headed motor, but, exact same weight car, same trans, same gear same everything.....except the motor. It stalled 6600 in this other car, which ran 8.40's at 161...........what does this mean when it goes to 7200 in mine??? Am I making this much more power?
Could be the SV -1 carb, which is absolutely nasty on the response / idle quality......

Guess we will find out tomorrow.....

Its a 9"...

I'd send it back to ucc and get it restalled. I'm ditching my 8" and going with a 9", mine figured out at 28% slippage at the bash on the first full pass.

might try some different fluid to see if it will tighten up a little too.

28% is leaving a lot on the table Dave! Just think what it will do with a good working converter!

yep been on the phone with Lenny..... Just need to save up the $$$ cause the good stuff ain't cheap!

Just picked up some JD hyguard, will try this first to get a baseline on what needs to be done.

28% out the back door is insane, dfree.....I just can't see this one being loose in the top, but we will see....

7,200.....it's gonna break something or flip over backwards.

If it doesn't blow the tires off, it's going to leave HARD!

with that much power you will not see any or very minimal difference with the JD oil. just send it back and get it done right. that seems like an awfully small converter for that combo. the smallest we've ever ran was a 9.5"

Well, I'm still reeling from the worst shakedown of a complete new chassis, and drivetrain combo ever.....

Never made a full pass.........4 rocker bolts pulled clean out of the head, and to top it off, destroyed a brand new slick coming out of the burnout box, caught the front of the wheel well, and turned the fender lip, ripping it right out, and slicing the tire clean thru all the way around.......

The only thing I can think of, is im glad all this happened when it did, and its funny, the car stayed up till I rolled to the beams, and when I stopped, it tilted back/to the right.........must of been the anti roll bar keeping the car up......

Oh well, at least all the cards are on the table now.......hope to have some decent results shortly....
