Hi guys, just bought this car for the motor a 13b streetport by Atkins,Holley carb,Racing Beat intake with an adapter between the intake and block. I just got the motor running and it sure sounds more than a sreetport (still don't know how to post videos ) so maybe by finding the carb size will give me an idea of the motor port or if you know other way let me know. Thanks in advance [URL=http://img129.imageshack.us/my.php?image=1000240wp5.jpg][/URL[URL=http://img404.imageshack.us/my.php?image=1000245tu8.jpg][/URL

 

maybe a 650 doublepumper, cant really tell, a lot of holley 4 bbl's look the same on the outside

 

If it really is a atkins rebuild there should be some numbers stamped into the rotor housings email them to dan he will e able to tell you all about the motor.

 

Yetterben is this what your talking about?

 

few more picture of setup

 

On the front of the air horn there are numbers for carb. If you look on Holley's site, those numbers will referance the carb info. http://www.holley.com/types/Double%20Pumpers.asp

 

Thanks, very good information guys.Tomorrow I'll check with Atkins and the Holley website to see what I got

 

Forgot to ask if this carb looks like a RB carburator? Or are this Holleys so much alike?

 

If memory serves, all double-pumpers had the chokes and choke tower removed. I imagine you'll find a 650 or 465-cfm Holley 4160 when it's all said and done.

 

yeah those are the numbers call atkins and run them buy dan he might still have them on file!

 

First thanks to all for the help, got the carb# matched to thishttp://www.holley.com/0-4777S.asp now as for the engine I email Atkins the #s to see what I got.

 

Thats a Beast of a carb! maybe you have a bridgie

 

I sure hope so

 

The fan is eating your fan shroud. It's probably finished by now.

 

Okay do us all a favor...no that is not a racingbeat holley carb...That carb is a double pumper carb anywhere inbetween 650-750...to put this issue to rest on the back side of the carb facing the driver side fender there is a list of serial numbers...post those number up here on the thread...and any one of us can look that number up on jegs, summit, or ebay...easy fix...

 

Teddy. I already found out that the carb is a 650 http://www.holley.com/0-4777C.asp .... now I'd like to know what motor I got .I called Atkins today and they said the #s are from 1999 and that they only keep records of 3 years. The previus owner told me that it was a 13B 6 port streetport but to me the way it sounds it could be more than a sreetport....now I need to figure out how to post a video

 

So, why not just freaking look? 4 bolts, 2 screws, 2 freeze plugs and some antifreeze will get you a good look at your intake ports. Slip a dental mirror into one and you can learn quite a bit. Have a look.

 

post the video on like image shack or photobucket.

just take it with a digital still camera. should do the trick. You say it "sounds like more than a SP".

How, like idle, or full out or what?

 

come on.......BRAP BRAP BRAP BRAP. Thats a fawking huge carb for a street port!!!!

 

nah a 650 on a street port is not that big bro...takes the right tuner who know what the hell there doing to make it run right is all

 

come on now man...i don't mean to knock but just take the carb and the intake mani off and doing your home work...wouldn't be to much harder from there to find out what you got...

+1 with you on this...

 

LOL, look at the plates on my carb....8000 cfm on a half bridge

 

duuuh, sticky key, "800" cfm

 

Intake coming off tomorrow for dental work Here is avideo of the exhaust and motor . http://img532.imageshack.us/my.php?image=1000265ga2.flv
