Forum member bjankuski recently pulled an 11.9xx @ 111 mph with a 355 ci.

Forum member "Ralph" has a stock bottom end and think his bet et is a 11.6xx

These are the only 2 that come to mind off hand.

Check out Beach Bums "proven setups" page. Lots of info on his site.

:cheers:

SR/219/190s/PT converter and almost any gear will work. I've gone a best of 11.62 and a best mph of 117.6 in -800ft DA. I now run a little heavier for consistency and she'dl usually go 11.8s in 1000ft DAs, that is until i had the converter loosened...big mistake. Need to have that undone over the winter.

Ralph, how loose did you go with the converter? What did you have previously?

The converter was their std 2800 stall unit. And it probably flashed to 2900-3000. It was plenty tight on the street, so i figured i'd have it loosened a bit since my torque peak should be around 4000 rpms. I didn't want to lose any mph and they assured me they could loosen it about 200-300 without hurting the efficiency. WRONG!!!!

It doesn't feel any looser to me and the car 60s about the same, but it's hurt after that. I estimate i lost almost a tenth and 2-3 mph in the 1/4 with all increments suffering after the 60 foot mark. I assume it's the converter since its the only thing i've changed since last year. I've gone over everything else i can think of. Going to have Protorque undo the change after the season.

Maybe i'm trying to squeeze too much outa this setup. For the last 3 years, everything i've tried hurt me considerably and i had to undo it.
