Drag Racing Tech - BBC Burkhart motor plate questions ??? Help

Ok i have what I believe is a set of burkhart plates ...I bought them off a guy on here ...I am mocking up my 555 t-400 ford 9 inch combo
The plates offset the engine to the right ..what rear trans crossmember/mount should I be using ...i have a manual trans crossmember with a 1" spacer then a poly mount ..which i read was the hot ticket ..when looking through the mains and empty trans the pinion is higher than the crank centerline !! is this normal ?? i can raise the rear of the trans or lower the front of the engine to bring it in line ...or is this normal ..
...maybe Burkhart can shed some light on this or others that have done the BBC conversion

Thanks Dave

I'll bump this back up. I'm curious too.

CHEVELLEDAVE, Chuck at Burkhart isn't the internet type! why dont you ring him directly for your answers 217 855 8660, im sure he would be glad to help.

thanks ...it appears that they may be madman plates...i milled about 3/8 of the the plates ...getting closer..still need about another 1/4 ...just whittling away a little at a time...will post pics when i get it done
