RE: [BaadAssGremlins] Re: I just dont know anymore :( :( (Building my 401)

Well, a stone-stock 401 in a Javelin for 1972 was in the high-15s, 
so a rather stock 401 in a Gremster, provided you are controlling 
traction well enough, should easily get around the 14.0 mark.

The '72 Randall XR Gremmies, in 'base' form, meaning they yanked a 
304-2v and plopped a 401-4v in it, then slapped headers on it.... 
they ran 13.6s reliably while being as streetable as any other 
factory-401 car. Even the warranty was intact.

They detached the pipes from the headers on a later run and got a 
13.22 pass out of it.

The same car, running  a 291 duration, 477 lift cam, 750 carb, 
headers, and a 4.10 rear saw a best of 12.75. That's with a stock 
401 intake, stock heads/rods/pistons/crank, etc.

[Above info from Super Stock magazine, August 1972]

I say slap a Performer cam and intake on it with a 700cfm carb, a 
good flowing set of mufflers, a shift kit for the tranny, an Ignitor 
pointless ignition mod, flow the heads, angle the valves and add a 
3.54 twin grip gear set and you should be seeing the 12/13 barrier 
pretty quick. Some wide meats in the rear to aid launching would be 
good, too. And pump gas is just fine in it.

Oh...and for MONEY'S sake, do an oil system mod!! Davis can tell 
you all about those and their benefit. Don't leave home without it.


P.S.- here's something I didn't know...grab a set of 70 to Early-71 
304 heads. They have the early hi-comp 51cc design you desire and 
the dog leg ports. They have smaller valves but can be modded to 
accept the valves from your 58cc 401 heads by any good shop. Viola- 
you have hi-comp 401 heads for far less than anybody will ever sell 
them to you for. That should knock even more off your ET.

Happy hunting! :)

I see what your saying. But I started out with the assumption my 401 
was a 9.5 CR.

I bought parts accordingly and took advice without proper knowledge of 
what I really wanted.

My mistake and I am paying for it now by having to tear down my motor 
again.

So heres where Im at.  I want high 12's low 13's 

Can that be done by leaving the heads alone and knocking down the cam 
to the 214/224 grind adding the Performer intake and going with a 650 
or 600 carb? Maybe even a 50 or 75 shot?

Im listening, I really am.
