Ethan, i love a good discussion  thats whats great about this forum, why do you think they would put the same jet and needles in those 2 engines , you can throw a 350 in the carb of a 454 , where is all the fuel coming from to feed the monster no pun intended , I'm just trying to figure out gm,s thinking.

 No, I completely understand your point of view. Maybe it was different in the 80s. What I mean is different size passage ways. I don't know, Jeff. Your guess is better than mine.

Cliff Ruggles:
The 17085212 and 17085213 carburetors are heavy duty 454 Motorhome units.  They were set up for 454 towing engines, and tuned completely differently than other q-jets from that period.  They also take special gaskets and rebuild parts, so you may find them working poorly unless the correct parts were installed during the rebuild........Cliff
