Hi David.  You have to wonder if any two people have the same system :-)
If
your injectors fit the manifold, and not the TB, then you have something

completely different from what I have.  If that's the case, there's no
reason
to think the injectors will be the same.  I do know that there's a 50
lb/hr
(525 cc/min) Rochester injector sold for the TWM TB, that happens to be
high
impedance.  That's what I'm shooting for.

Cheers,
Rusty
 
Those are the Rochester injectors I have in my 3-barrel TWM throttle
body.  
Got 'em at "Smoky's"; the local speed shop for $84 each.
