I have a Holley carb on my Weiand stealth intake manifold (#8012) which is on a 429 bb in my truck. My question is, given the numbers Rb4011 and 3448 stamped on the intake part of the carb, and 12r-10552b molded onto the side of the carb, what model of carb is this??? I've looked all over the net and don't have a Holley manual to help.
Thanks for your time,

Look on the front/right side of the choke horn for a LIST#

 

R84011 and 3448. I posted RB4001 in my last post, but I meant R8.

 

Universal off road 750 cfm is what I have for that number R-84011AA

 

What's meant by off road? Like it's built to withstand more vibration and bouncing around?

 

My guess is center hung floats.

 

Sounds good to me
