any difference between sbc/bbc crossmembers?I have current a 327 that will be out for a 505 bbc, the sbc has a th350, the 505 will have a th400, any difference??

 

No. but you have a little play with the bolts for adjustment

 

yes the bb sits 1 inch over to the passenger side of the car and the bb crossmembers for turbo 400`s was also 1 inch over, you could possibly use the sb one and drill holes for the new position but factory bb 67-69 camaros had a different crossmember for the 400 turbos.

 

here is a link to a thread discussing the issue and has pics of the different crossmembers.

Thanks man, I got a hook up on a brand new bbc member factory from gm for 35.00

 

The heater core and cover are different too.
