Question holley 8546 carb ?

I have a holley 8546 on my blazer and was wondering what size it is and if it is too much carb for a mostly stock 350 (edelbrock intake and dual exhaust)

BTW I can't get pix to post WHY?

It has a "L" in front of the #, what does that mean? In one place it said "LAST 8546".


Does this mean it's a stock carb?

Most Holley's will list part #'s this way..

List(or L) - *****

Example would be the universal 600. List - 1850

I cant remember if OEM holley's listed the #'s like that though.

I would say that going by the numbers, the carb you have would have been from the 67-72 era. I'm not 100% sure on this though... just going by the holley site.

If someone has the numbers, could you tell me what a 7855 is? It is a 4175 type, but i bought it used and I would like to know more about it.

Here's a good listing of most Holley applications and where they came from.
