Help me decide which carb to rebuild

(1/2) > >>

Mudsport96:
So I currently have a Edelbrock 1901 on my very mild 355 right now, and it drives very well except at the top of the rpm range under heavy acceleration. I have my heart set on not digging into it if i don't have too because it no questions asked will fire up every time. Maybe after i rebuild another and don't screw up ill do it.

Anyway, on to the carbs i have acquired.

Had two given to me recently, a 17080205 which seems to be an early 80s truck unit and a 17057229 which i could not find any info on but found a ****7228 which the jets and rods match size wise.

ALL THE APT SCREWS are loose, got very lucky didn't have to heat them or anything
 
Now the numbers:

17057229

DCRs .050
Idle Tubes .030
Upper IAB .070
Lower IAB .063
MAB .050
Idle Bypass .125
Pri. Rods 39B
Jets 64
Secondary Tube Rest. .032
Secondary Rods DG
Hanger J
Fuel Seat .130
Shafts needs bushed

Carb 17080205 Has been Remanned but everything SEEMS to measure OK EXCEPT the Idle Bypass and the primary plates look staked to get them below the transition slots..(i have extras on other carbs)


DCRs .063
Idle Tubes .035
Upper Idle Air Bleed .070
Lower IAB .077
MAB .085
Idle Bypass .039 (Has tin plugs that have been drilled can remove easily)
Sec. Tube Rest. .033
Jets 72
Rods 51M
Hanger H
Sec Rods DR
All the electric choke stuff, choke pull off and linkage is gone as well but no play in throttle shafts

And my 7041200 unit
Dont have all the measurements for this one

Idle tubes .039
DCR .053
Upper MAB .118
Lower MAB .085
Upper IAB .070
Lower IAB .063
Idle Bypass .098

And shafts need bushed

Any unit better than the other for building

Thanks in Advance

Andy


ps engine specs

350 .030 over, comp 268he cam 218@.050 I/E, .488 lift with 1.6 rockers, factory iron intake 346250, 441 heads, about 8.5:1, and hedman block huggers through 2.25 duals. Stock 900 rpm converter and 3.73 gear.

Frank400:
One  thing I can tell you is that the 7041200 is from an LS-5 1971 Chevelle and is worth good money.

Mudsport96:
The 7041200 actually came off of a 1971 Caprice with the 365 horse 454. I know because I actually took it off that car in 1997 and put an Edelbrock 1910 on it.
However, I have seen things slip by quality control before and maybe it got stuffed in that car because they were a carb short or something.

Cliff Ruggles:
The first decision to make is whether to have a divorced choke set-up or electric?.....Cliff

Mudsport96:
Well the current 1901 runs the divorced and it works good, idles for a minute or two and by the time I hit the first stop light she's off choke. So I could use that on the two others if I went that route, but the 17080205 is an electric choke but missing literally everything on the passenger side of the carb... Choke, pull off all the linkages. As much as the car is actually driven electric isn't that important, and it won't be driven if its below 45-50 degrees anyway. So probably will stick with the divorced choke.
