I tried my new converter today. Unplugged the two step and stalled it up against the transbrake. Against the transbrake it stalled at 6000. What do you guys think?

The converter is a brand new BTE 9" soft hit. It's a 9" Steel Stator CCX 200+. The CCX stator is for a full .500 tree and softens the hit to the tires a little to help out on marginal tracks. Supposed to be .02-.03 slower 60 ft times, but then make it up on the top end. It's with a new BTE pro-brake glide in my Undercover dragster. I know glides are not the favorite here, but this is about the converter. The whole engine-trans combo is new to me. I was planning on keeping the rpms down to increase the longevity of my Scat cast steel crank. I was hoping to launch ~ 4000 and shift ~6400-6500. Is my converter too loose or does the engine make more power than I expected?

The engine is a 557 BBF. Alky with a single 4.10" Flying Toilet mechanical injection system on a Victor 460 intake. Cam is .770/.770 roller. (.740 after lash) 275/280 @ .050. 306/316 adv dur. 110 lobe center installed straight up. 12.2:1 compression, 4.440" bore X 4.500" stroke. Timing with a crank trigger locked at 36. Heads are Blue Thunder aluminum w raised BBC exhaust. Heads flow 380/265 cfm. 2 1/4" headers.

Should I try it as is? Raise my shift points? (makes me worry about the crank) Send it back to be tightened up? (they'll do it free) I told BTE when I ordered it that I wanted 52-5400. What should I be looking for to match the cam?

The salesman (??) talked to his shop guys and they wanted to give it more stall than 52-5400. But I stuck to my request and was assured it would be the rpm I requested. I figure this thing is a torque monster if it's taking a 9" converter to 6K.

BTW, if it matters the car will be used mainly for 1/8 brackets. It has 33" tires, 4.10 gear and should be ~ 1850 lbs with driver.

Thanks,
David Cole

Sounds too loose to me. With the shift points you want to use I would think something around 5000-5200 would be optimum, especially with the amount of torque that motor is making.

If it were mine, I would run it a couple of times first, then decide if I wanted it tightened up and how much.

Dave,

Scat cast steel crank?

I know it came with it, but it wouldn't have been your first choice, I bet.

You ever thought of running hi gear only? I would try it just for ****s and giggles, I'd be fun to let them go then blow by them at the stripe. That converter might do ok for that. Talk to "One Speed Ralph" on DRR about it.

The options for the BBF are very limited when it comes to cranks. There are no cheap forged cranks like you can get for the SBF. (Eagle and Scat).

Choices for a BBF stroker:
1. offset ground stock cast iron crank. $400
2. Scat cast steel. $500, in stock at many places.
3. Custom forged crank, $1900, 5-6 month wait time to get one.
4. Custom billet crank, $2400, 5-6 month wait.

Hadn't thought about th ehigh gear only deal. I've seen Ralph's posts. I night look into it.

Later,
David Cole

Dave,

I would if I had your "ride". Like a throttle stop and perfect traction every time. Bracket racing doesn't get much better than that.

Dave,
Try asking Kenny Ford @ PTC. He usually hits them pretty close.
