2 brand new holley 950 sc carbs. bolted to blower and never had gas through them... part # 0-80577s $900.00

I am still interested. Just want to confirm from Holley that the boost ref. PV's can be altered to that of a NA/vacuum. Has the linkage been cut for clearence?
Thanks,
John

they are the way they came from holley .. never cut..

One more question. Do they have the j-tubes or are they standard? Also just curious as to how you go about altering or blocking the boost ref? Do you know if they are referenced through the carb body or in the metering blks? If in the body could the holes be soldered? Otherwise in the metering blks. would they have to be replaced? Just want to be certain of what I would be up against. Good price though...
Thanks,
John
I guess I should have said like 5 Questions. LOL.......

I will check tomorrow. I know you can block the boost reference.. it only controls the power valve.. if its blocked they work normally..

I understand. If the PV didn't play a vital role in fuel delivery I would have no concerns. Regardless were on the same page.



I remember years ago it when we were doing just the opposite. Blower Carb - WHAT THE....... Make it work, "IMPROVIZE - OVERCOME - ADAPT"

do you still have them?

Yep

just my o2, a boost referance carb also has the holes drilled out behind the power valve...

can you email me pics? Where are you located? Phone #
