I know this mannnnn! 
The guy has to buy a new TB. instead of paying 340 for a new GM one, cant find a used corvette one right here right now, so might get a 90mm. He doesnt have intake money right now so hed only lose money on the spacer now.. and can bolt it to a90 when he does his planned h/c later

Hmm, that's a problem then. I've never seen a 90mm to 78mm reducing spacer.
He can slap on an LS2 manifold, that has a 90mm 4-bolt opening, and will work with all LS1/2/6 cathedral port heads. It will have similar power to an LS6, and he can just swap it out for a FAST later on.

I've never seen a reducer spacer either. Might be better to just wait and put on a 90 when he gets a different intake. Save his $$$ and do it right the first time.
