Re: Can I use big block stands with a 406 in my '68?
The only advice I can offer, there are other experts here, Eric is one of them, the trans xmember for a BBC has a five-sided hole for bolt access where the SBC is a four-sided. If you have a SBC trans xmember and BBC engine mounts, yes, it will be a little hard getting the bolts in the trans mount. And, the xmember can be installed on the subframe backwards making trans install more difficult - OE shifter holes, the holes on the edges, go towards the drvr side.
Years ago, I helped a friend install a 396 into a SBC equipped '67 Camaro. Transfusion went well from what I remember. So, with this line of thought, a SBC into a BBC should be relative easy, but not needing four crowbars and a ratchet strap.
One thing is the isolator width, the engine block mount, has to match the frame stand/mount.I would believe it would be ideal if you installed the BBC insolators onto the block and go from there.
Standard OE design oil pan should not hit the frame, IMHO, it should clear.Let us know what you find.
