I pulled a running complete motor and tranny from a 77 MGB, and stored it away in my garage. I have a 72 that has a seized bottom end. I just finished pulling the carbs, exhaust manifold, distributor, and cylinder head off of it. Is there anything else I should pull from this engine before I junk the car? I have a 72 MGB former race car that I am slowly restoring and want the good motor for a spare if I ever need it. Just want to make sure I don't junk some hard to find piece. What are the major differences between the 72 and the 77 engines?

'72 might have the desirable flat crankshaft as I remember...also should have the desirable straight rods that have the pistons clipped on them not pressed.
I'd at least look at those & pull them.....& if you were closer, I'd come get them!

I'm with Tony.
Pull the block apart and see what "seized" means. It might be only a "slightly" bad rod bearing and if that is so you can strip a ton of stuff that might otherwise be irreplaceable or very pricey. Cams and followers are disposable, but those rods and crank and even the block have considerable value under some circumstances.
As for interchangeablility, you will have to do some research through the usual books by Burgess and Porter, but generally speaking almost everything is interchangeable, so don't trash anything until you are completely finished with your project, and even then make a lost and post it so others might find treasure in your trash.
"Junk the car"? What is there? Post some pictures and a list of stuff before you send it to the crusher. At least keep the chassis ID plates and any other car specific information that you can scrape off. Ask Tony of there is a value there. He'll 'splain it to you. ;-)

Car was nice enough to save, however, it has been off the road since 1980. No hope of getting a title for it here in Mass. It and two 77's came as part of a package deal I got when I purchased a TR8 coupe back in January. The PO had pretty much taken the two 77's apart to restore one out of the two. A neighbor saw the cars and said "hey' I got one of those in my garage. Do you want it?" That is how he picked up the 72. It sat outside for the last couple of years beside the two 77's. I ended up with three truckloads of MG's. The worst went to the scrapper the same day. The nicer of the 77's gave up the motor and tranny before leaving this world. For the last couple of months, I have tried in vane to sell the 72 as a complete car for $400. No interest from anybody local. For the last month or so people have been coming by and plucking pieces off of the car. I got my $400 and them some. It still has a complete set of wire wheels, as well as other nice pieces. Spring is here. I'm tired of looking at it, and I still have a covered shelter with alot more MG parts than I will ever need. It wouldn't be so bad if the MGB was the only hobby car I have, but it's not. It must fall in line with several TR8s, TR7 parts cars, a complete 72 MGB parts car with title, a BMW 2002 race car, and a TVR 280i rolling chassis and body. Any body want any TVR body panels? I just want the chassis for a platform for a fiberglass 356 body. That is the next project when I finish the current TR8 in the shop.

You ought to be able to get a small fortune for the TVR stuff. They are in great demand and bring lots of bucks. Be patient.

90% of the time, when a engine is seized up from sitting, it's the pistons stuck in the bores, which if you are boring the cylinders is no big deal. I disassemble about 10-12 of these engines a year and see it quite often. Even if it's a spun bearing, normally a rod, everything is still fixable, I got a engine last year from a customer for rebuild, he had spun a rod bearing, I ended up having to replace the crankshaft and one rod, but it's back on the road, and that is a rarity with stuck engine, mostly it's just stuck pistons from sitting.
I'm in Carver. There are several heads to choose from here. I have one on a shelf, one on the complete engine on the floor of my garage, one in the trunk of the car with the seized motor, and one on a parts car out back. Come and get one. Send me a PM with your email and I'll send you info on how to get here. Some guy was suppose to come by today and buy the wire wheels I have. Since it's almost lunch time and I have not heard from him, I guess he's not coming.
