You are being waaaay too vague here. How many cc's are u running, what mods are already done/going to do in near future. What mm are the Full Specs?
All carbs are good carbs when tuned right and they are all junk when not tuned right. If you have somebody that can help you that is good w/Full Specs-stick with em, If you have somebody close that is good w/Blackjacks-run those. If you are good at getting carbs dialed in-run what U like! Not that it really matters, but I have had Full Specs, a Novi, and now have Blackjacks and the BJs are my favorite. (but I have a very good friend that helped me get them dialed in very quickly-like 5 minutes).

How much experience do you have tuning carbs? Do you have a friend close by that is good if you are inexperienced? Can u feel the diff between a lean hesitation and a rich bog?

I will be running 48mm dual Novi's on a 701 bored over 1mm. Here's my mods.
64x cases
61x cylinder
FFP mod chamber
ADA head 35cc domes
MSD enhancer
Riva waterbox
R&D intake manifold w/ spacer
V-force III reeds
K&N flame arrestors
Jet works flow valve
11-17 impros hooker impeller
PM me and I can give you my jetting for a baseline. These carbs are the F-bomb Novi's. Jetting by Tim judge.
I've also run dual 44mm Blackjacks on a similar 82mm ported waveblaster and they hit hard!

I agree.....I would not use anything over dual SBN 46's on a 701 motor. Anything under 800 cc I would not mess with the bigger carbs, especially straight bore race carbs. If your carbs are bigger than the motor requires it will be PIA to tune.....IF you ever get it tuned.
38's have allot of snap but just don't make the mid to top power. I found on my SS lamey the 48's make great mid to top and are nice down low.....but the 46's are cleaner and snappier. The Riva's and full specs made more power but were more difficult to tune. The dual 46's are so nice in comparison.
If I had to choose between full spec race bore carbs and the blackjacks, I would choose the blackjacks. I think they will be cleaner and have more snap down low because of that venturi in the throat of the carb.

Ditch the coffmans and get a b-pipe. A friend of mine did that swap and it made a really nice jump in power and response

We are not talking racing with a revved up motor awaiting a hole shot...

Neither are we. NO 38mm carbed 701 will hit, bottom to top, like a properly tuned NOVI. But, there in layes the problem...... properly tuned.
This site can be great for its informational value, but it can also be the mecca of misinformation, too. But, its cool, keeps the price of good carbs down.

As I stated earlier, I ran a single Novi 48 F bomb for 1 full year and loved it. Dam good carbs and was ridiculously easy to setup because I tried the single setup. Took about 5 minutes to get really dialed in. lol There is alot to be said for bolting on and running good! I must say tho-I would not trade my 2 BlackJack 46s for 10 Novis now and you can buy 2 BlackJacks for the price of one Novi or Full Spec. carb.
Final clarity here-they are all good when properly tuned!!!
