Best tri deuce set up for nailhead.

I checked the archives to some degree but just wondering what is the best carb/mainfold combo for a 401 Nailhead.
Second question, Is the distributor on the Buick unique to the nailhead or what other GM or aftermarket dist will work?
Thanks guys.

nailhead distributor is unto itself. I have the MSD in my 57, but you can have gmc bubba redo the stock one.

as for 3 deuces, never thought to run one on a big nailhead....

 

Yep, dist is unique to the nailhead.
I set up a 425 with an Offy manifold and three RetroTek 97 style Fuel Injectors. Look like 97's but don't leak and actually perform. Works real well.

 

In my opinion, the best multi carb manifold for a 401 is the factory 2X4 set up. They start, idles, have good throttle response, and go like a raped ape. I ran three twos on a smaller nailhead, but those manifolds wont feed a 401. I ran a 364 with a 327 truck carb in the center and two 283 carbs on the ends. If you really need three twos, look for a center carb from a 421 Poncho or a 394 Olds.

 

3 Rochesters on an offy It's a stock 64 401 works great. Slowly collecting carbs for the 6 deuce 425 project....

 

3 ROD 2G's ontop of an Offy on a 64 Widcat 401

 

how do the 401's respond to 3 small carbs?

 

I've seen them do ok with 2gc's, 94's or 97's would be silly. Nailheads like a lot of carb.

 

Thanks for the input gang. I was thinking 2-4's origionally but the 3-2s look cool.
I'll go with the power.

 

How do 6 97's perform on a 401?

 

Distr. on Buick is unique like guys just wrote. Nailhead has shorter distributor than sbc, so it will not fit. Anyhow, I've read article/post here at HAMB that someone combined sbc magneto and nailhead's stock distributor. It was quite simple work made on a lathe.

 

How CFM's of air do 3 Rochestors have or how many CFM's does one have any one know.

250-270 cfm each.

 

I'd like to put three twos on my 55 nailhead, but its a baby nailhead a 264 and I don't think they make that intake.

 

I have an Offy intake with 3 rochesters ,all set up with linkage and all. Never ran it on my car. Thinking about selling it to fund another project. I paid $1,000 for it.

 

264/322 manifolds are out there, more manufacturers actually made 3x2 for those engines than did for the 401/425's.
