7-pin would be full computer control; 1980 1/2 and newer until the distributorless ignition was introduced.
I suppose any computer-controlled 350 with a distributor would be a core; change the...

Excess restriction. Oil pressure crushes filter media.
First Guess: Filter plugged with thick Moly grease from camshaft break-in. Moly paste camshaft lube can plug an oil filter in 20-30...
It's called a "heat riser valve" or sometimes an Early Fuel Evaporation (EFE) valve.
Yes, they can stick (seize) shut (or open, or anywhere in-between).
No, they are not rocket science. If...
DO NOT under ANY circumstances spend money for a production-line rebuilt carburetor.
They are JUNK. Mis-matched castings, bastardized calibration. You will probably NEVER get it to work...
The straight-cut gears means it's not a TH 400, it's a TH 475.
Been using the straight-cut gears in motorhomes forever.
There are additional upgrades/calibration changes that the 475 has that...
No, you didn't fix it. 210 is still too hot for cruise and idle.
210 isn't hot enough to damage the engine, but at cruise and idle you should be very close to the thermostat rating. Work the...
Far as I know, the BBB starter is the same as the Chevy "small flywheel" starter.
You'd have a zillion choices of starter motor because of the huge OEM and aftermarket support for the Chevy.
The '72 probably has larger oil pump suction drillings. The early blocks were drilled with smaller-diameter tooling; and was upgraded in '71 or early '72--I forget which. You would want to re-drill...
Add enough material to allow spread-bore carb flanges; and double-drill the carb mounting pads. Even if you don't do the actual spread-bore machining, at least allow ME to carve the manifold for...
A GM distributor from a computer-controlled engine (typically '81 and newer) will have no vacuum advance; and no centrifugal advance.
The module will have 7 pins.
You need to examine your HEI...

A 700 shouldn't need an "electronic controller" although it will need a simple vacuum switch and some wiring to engage/disengage the torque converter clutch.
A newer 4L60E would need an electronic...
That's a terrific price if the controller is included. I might be interested in a trans and controller (probably don't need the bellhousing adapter--let me think about that, and I certainly don't...
Because the reluctor on the distributor shaft; and the pickup coil, are set up to fire SIX cylinders instead of eight?
Change the pickup coil and the distributor shaft/reluctor as appropriate for...
My preference is to route the pcv hose to the FRONT of the carb; the fumes then mix better with the incoming air/fuel that flows through the primary venturis. There is--usually--a port on the carb...
A plain ol' ordinary 1/4" female crimp-on blade terminal works fine, too. It doesn't look right, and it doesn't positively clip on to the side of the cap--but it fits.
That was EXACTLY my point. They DON'T crap out at 4,500 RPM. Old wives tale.
I'm sorry I didn't see this thread earlier.
Did your manual tell you that GM used those tremendous wide gaps to fire a very lean and EGR-polluted mixture? Or that a common problem with gaps that...
Sort of. It should be switched so it comes on with the ignition, it should run through an oil pressure switch so it is disabled when the key is on, but the engine isn't running.
DO NOT use the...
What is a rebuild book? Are you looking for just a book to help rebuild the engine, or the whole car?
If it's just the engine, I strongly recommend you buy Stephen Dove's book: Guide to Buick...
If grandma was very elderly and not expected to live too many more years, and she needed the engine rebuilt so she could still get to church and pick up groceries, you could get by without boring the...
Should be all kinds of stuff available. For stock replacements, try NAPA. Performance stuff will generally come from Buick-specific vendors like TA Performance

First guess would be Pontiac. They also used four bolts to hold the covers on.
