I carefully profiled a stock '66 401 cam. These are the results:
Duration at 0.002" lifter rise:
309 deg Intake/ 298 deg Exhaust
Duration at 0.006" lifter rise:
271 deg Intake/ 266 deg...
Bob, I had these notes on file:
shop manual calls for the following:
Rear Carb -
Carb number: 3646S
Primary Jet: 120-256 0.092"
Secondary Jet: 120-222 0.070"
Metering Rod:...
Tough question to answer. I don't believe there have been many dyno tests done on different cam designs, so it's difficult to say what works and what doesn't. Tom T has done some testing, but those...
I wonder how well that 349 would run without the extensive head work?
The porting would be most beneficial at high rpms.
Peak hp was 370 at 5900 rpm, but it still made over 300 hp at 4400 rpm.
The LeSabre uses the 8.2 inch rear, same size as the Skylarks.
The other big cars like the Wildcat, Electra, and Riv use a different rear.

I have Moog #6197 on the rear of my 66 GS. That spring is listed as a HD replacement. Measuring from the center of the wheel cap to the fender lip, it is between 12 and 12.5 inches. That works great...
That would be Jim, aka 'Monzaz' on the boards. Good guy, knows the Buick rears very well.

Yes, he can hook you up with a carrier, gears and install kit for...
The dash pad is held in by screws at the upper lip of the chrome dash that screw into the bottom of the pad. Those are easy to find, bet you got them already.
There are also two pins at the very...
Marty's EELCO intake should be avail any time now. It's a square-bore, so an Edelbrock for a Q-jet would be a welcome addition. :thumbsup:
Good advise from Mottrodder!
Egge machine is the only current manufacturer of cast replacement pistons. Forged pistons are avail elsewhere (Ross, Diamond, JE), but are much more expensive.
Egge...
Piston Domes, measured:
Stock '64 401:
4 pistons measured:
46.1 cc

A new single 4bbl intake from EELCO is due out next month!!:hurray::bana::laugh_4:
POR-15 offers the Buick Green engine paint as well.
Accelerated Motion offers a 'turbo' cam for the Nailhead:

It has 0.466" lift, 216 degree duration, and 114 degree lobe separation.
Another option would be...
Cool!... finally some hot aftermarket parts for our Nails!!:hurray:
I'd like to see the dyno results!

They offer fuse block repair kits (look in the 'repair components section).
MAYBE they'll have something for you.

Create a nailhead aluminum manifold that would in it's design allow for bungs to install electronic fuel injection for each intake runner/[quote]
Good point. The old...
I've also seen ported vacuum on the 2x4 carb, 66 4 speed carbs, and 66 Calif emission carbs. The difference is in the carb itself.
Might be safe to say manifold vacuum was used on most 64-up...
They recommended 0.100- 0.120" back in the day.
But they had to consider timing chain wear and carbon buildup after 80,000 miles.
I honestly don't know what can be considered 'safe'. I've heard...
Stock Carter AFB was 625 cfm. Most guys recommend at least 750 cfm.
Found some great camshaft info on the CompCams site. They have a 'Master Lobe Catalog' that lists specs for the lobes used on...
The 79-up heads have a taller intake port for improved flow. Your 78 intake would bolt up, but there would be a port mis-match.
There's a guy on the Turbobuick site, dr_frankinstein, that may have...
Some rough calculations put a stock cam with 9.75 static CR near 8.5 DCR.
To maintain that same 8.5 DCR....
Poston NH400 cam would need static CR at 10.0
Erik's Comp cam would need static CR at...
I'll put it a slightly different way, and say the higher stall IGNORES the soft low speed performance of a big cam. At 3000 rpm stall speed, you just bypass the low rpms.:bgrin:
I've done lots of cam comparisons using the Dyno 2003 software.
There's a free download here...scroll down to the 'Software' section:
