Title: Which carb to use?
Post by: Mark R on September 09, 2009, 05:39:31 PM

Hi, I have three carbs to choose from, a 7027202, 17058284, and a 17056208.
All are currently in stock condition, but I have Cliff's book but not sure which recipe to use ?   

 My engine is a sbc 355, 10:1, World S/R heads, 170cc runners, solid lifter cam 241* & 249*@ .050
 .520", .540" lift intake and exhaust, Victor jr + 1" open spacer, 34*- 36* of timing, 2800-3200 stall, headers, 3.73 rear. Summit 140gph fuel pump. 

The car weighs 3750 lbs. Mostly sees strip but is driven to the track and back.

Thanks

I would use the 17058284 carb.  Which one look's the best to you.

Is there any reason you suggest that carb? That one is in working order the others are apart I was just thinking that one might be a better canidate for the modifications found in Cliff's book.

I agree on the choice, use the later model carb, and/or the one in the best overall condition.  Forget the early 1967 unit, they are best for restorations, not for high performance work. 

When selecting a carburetor, keep in mind that any calibration can be installed into any casting (non computer controlled).  This helps in the selection process.  Choose the carburetor based on fuel inlet location, throttle linkage, type of choke, vacuum fittings, etc. 

Then completely/correctly rebuild the carb, and calibrate it exactly for the application.  We sell complete HP kits and tuning parts to help out....Cliff

Thanks Cliff, do you still sell the drill bits? 

I think for my first attempt I am going to try it out on the 76' unit.

Thanks

We aren't selling them at this time.  We had some in stock, but they simply didn't sell.  It's difficult to sell good American made bits when you can buy imported China bits for penny's on the dollar....Cliff

bits, you might look at small parts.com. I am not sure of the quality though.  I wish I could get som decent american ones like the cleveland twist drill bits. Low on the funds

Won,t like the answer but e-bay has em, my personal thoughts if your only drilling that size hole and you break em, you are doing something drastically wrong!!

My problem has been with the quality of pin vices, as I've already got sets of quality number drills.

The "General" #92 pin vice I bought holds the drills so far off-center as to be very frightening.  They won't answer my e-mails about it, either.  The collets look like they were cut by a blind man.  Thanks for reminding me, its time to jack them up again...

Bought another brand of pin vice, but haven't unwrapped it yet...

The pin vise I bought only has one collet I need to get one to fit the smaller bits 61-80.

I got lucky and found an old pin vice at a swap meet. It has 2 different size collets and is of extremley good quality. The guy was like "what are you gonna use that for" , "I build carbs" I said. He says " most people dont even know what that is, I'm just gonna give it to you"  Its neat, it has a knob on top that spins the bit seperate from the body.
