It states it's for a TH350/SBC combo in a G-body, but from my research, all of the G-bods would be the same, except the TH200-4R cars...or if ya use a longer TH400. For us with TH200/350s, it should be good to go. I don't think the engine (SBC, BBC, BBO, BBP, BBB, etc) makes a difference with the crossmember so long as you mount the engine properly...not back-setting it. A great deal at about $130!!
