Default Has anyone went from a sbc to a bbc and slowed down? I have!

I went from a 500 Horse SBC to a 700 Horse BBC and slowed from 5.8's to 5.9's.

I am wondering what experiences anyone has had with this, I think the converter is my problem. It was built for my 535 Horse 406. It stalled 5400 behind it. Now it stalls 6200 behind my 468.

I thought it would work, now I am thinking it is way too loose!...

Any thoughts or advice would be greatly appreciated...

My 468 is a 12:1 motor with a .722 Roller and World Merlin III 320cc heads that have 2.300 and 1.880 valves. It has a 1050 Dominator with 38 degrees of timing.

My car is about 1950 pounds with the bbc and me in it... It has 4.86 gears (set up for 1/8 Mile) It only sixty footed 1.30 with the BBC and it had a 1.23 with the 406.

Thanks,
Josh
