Happens all the time.  All the time.
The only way to know for sure is in back to back testing.  They tend to feel
**quicker** since they use less throttle pedal movement to cruise at x
speed, and less movement for large hills, but at WOT suffers.

4*85=   340    340*.5=  680 HP

Gotta machine shop friend?.   Barry Grant sells Butterflies seperately, and
remachine a 350 TB to acccept em,  double check me but I'm sure they are the
same casting.
   If ya want a hand, remind me early next week, and I gotta do a junk yard
run, and I'll look in the "cores"

I bought a SBC TPI (all the mechanical stuff) for 250 plus shipping.  ECM
and harmess 50 each, I wouldn't go over 350ish.
