I agree that a properly prepped carb of any size will work, I ran a 1250 for years on mine. In order to get it consistant coming off of the stop though, we had to run skirts on the boosters in order to get a consistant signal through the carb. The 1050 seems to be a little better at having a consistant signal. I would probabley run a little more mph with a 1250, but for the most part, I am happy with the 1050

Chuck,
I have a Quick Fuels reworked 1050 for my super gas 565 from a few years ago. Since I installed an O2 sensor, I found a very lean idle condition and getting info from them on air bleed tuning is like pulling teeth. Did they provide you with any tunning advice?

Hi Guys, Thank you for the replies. What type of throttle stop do you guys run ?. Under carb or inline ?. The 1050 carbs that you run are they 2 circuit or 3 circuit ?. Have read a story that you need to richen up the intermediate circuit to run on the stop. Hmmm, 1182 hp with a 1050, thats is pretty stout !. Thanks again for the replies, 3 1/2 weeks till my car gets here cheers Patrick.

I run a 3 circuit 1050 (modified for increased cfm) with an inline stop.

Be Careful messing with Air Bleeds without proper advice- Call Marvin at Quick Fuels - Mine is a little on the fat side but my Motor likes it that way. Look at your Plugs- they tell all, it might be lean at idle and ok on the high speed side, Research and Read !

3 circuit with an under the carb stop.

Have you ever heard of Smith Brothers Chassis, they had a shop in the Massachusetts area. They built Pro Stock cars back in the .90's. I believe they sold out to some one but am unable to find out anything. The car i bought is a 1990 Beretta Pro Stock car built by Smith Bros. Thanks Patrick.

Patrick, have you been able to find any further info on Smith Brothers Chassis or build details of your car

regards

Hi Rod, No nothing a s yet. I thought Bob from Massachusetts may have heard of Smith Brothers Chassis as he comes from that area also. Or maybe anybody that remembers Pro Stock from the early .90's. I did speak to a guy at Lebanon Valley raceway and he remembered them , but did not know who took them over or bought them out.
Cheers Patrick. 2 1/2 weeks to go.

I did hear of Smith Brothers but that was quite a while ago. I do not know who, if anyone, had taken over.
