What do ya do with a big ol Nailhead?

401 nailheads - 4.1875" bore x 3.64" stroke

Scuse my ignorance but that's considered a long stroke? Yer standard Shivvy 350's aint much shorter than that. And the 383's they make outta em are longer stroke.

Where's the limit of going from "short" to "long" stroke?

Dynaflow's ****!! Or actually, they blow fluid out the rear seals that don't seal worth a **** anyway.

 

Damn you guys get all worked up over nailheads. I finally got some responses to a post and it turns into a cat fight, I hope all you guys can come to the drags and settle this **** with a bump-n-hug. Thanks for the advice and the link to the tech article. I see NW speed equipment has me covered, as long as I can get a second morgatge! I think I'll just keep it stock till I get used to it, but it will need a rebuild soon seeing that I'm going to drive the **** out of it. I'll find the weak spot, I always do! How are all those multi-carb intakes for drivability?

Valentine your about a week to late, just picked up the expensive ****! I'm sure I'll need some more sooner or latter, nice to know that ben is still alive and not incarcerated. Looks like you almost got a driver, and your an OSR hero too, man I got to get you to sign your book!

as far as most of the Nailhead guys are concerned he's the top dog...

 

The runners on the Offenhauser dual quad intakes are not well suited for progressive operation. Might be ok for a mild engine...check them out before you buy. Good luck, Frank

the 322's had a long stroke, i ***umed 401's were similar, my bad.

 

what needs to be done to a sp ****** to convert it to a regular 400.

 

Why would you want to? The Switch Pitch rocks. It gives yout he best of both worlds...


Also Tom Telesco is just about finished with roller rockers for the Nailhead as well.

 

Another thing if you're into Nailheads you may want to join the yahoo group NailHeadBuick There are quite a few very knowledgeable guys over there that can be of help...

 

heck this reminds me that i think i have an real good condition 401 nailhead with offy valve covers and a finned valley cover somewhere in my garage, now where did i put it. and what will i put it into
heck i have 8 engines standing around in the garage to put in my cars ,

I wouldn't say hero. Maybe a hero in training. I am still in the plowboy training program. I plan on hitting it hard this weekend if you want to help with the floor pan. I am sure I will need an extra pair of hands.

 

Matt, Heath will be hopefully be getting kicked into high gear on the "Hero in Training" program this weekend. Look for supertopsecret (tm) things to be revealed soon.

Of course the Champaign county demolition derby is taking place this weekend so certain events in the beer tent will take priority. Besides, it is too hot to do anything in the daytime anyway. 97 degrees with 75% humidity.

 

If I can remember correctly you just need to change the front pump and converter.

 

and when you do send them to me...

 

I plan on trying to keep it the way it is. My issue is I bought a non running motor and ******. If for some reason the torque converter or anything else is toast I was wondering what was interchangeable.

Also who works on these ******s...
