Projects Lets play what motor is in my wife's 51 Mercury?

Bought this car for my wife last year .Guy I bought it from didn't know what was in it but he said it would blow the tires off years ago.Time to start working on it just wanted to find out what I had.Thanks for any help.

 

G.M.,maybe a buick?...Do i win?

 

Oldsmobile

 

Oldsmobile.....

 

Probably a 455. Very popular and available. Lots of torque..

 

my guess is 455 Olds, I have an old magazine with an article on the swap

 

Definately Oldsmobile!

 

i think Olds...

 

Would be great to have that article uploaded to some sort of webpage...

 

Not sure if Olds is the same, but Pontiac puts the cubic inch of the motor cast into the block under the heads...

 

Yep looks a lot like the 350 Olds in my buddies 71 Cutlass

 

Yep, HEI... Qjet.... Olds 455
Pic of one on Clist.......

My good friend called said he would bet money on 455 Olds .

 

I say Olds 425.

 

Wait, I missed the smog attachments, probably an Olds 455.

 

Looks like olds to me! What's with that giant spring? Hope it wasn't used for the return spring on the carb,LOL!!!!

 

Is there any way that this might be a 307 Olds? I really hope for your sake it isn't but... it looks like one to me. Hmmmm

 

Hood spring .And lots of rat shit.

 

Thanks for all the input .Now I have to decide 500 Cadillac or this nasty thing ?I am almost positive its a 455 would it be a rocket motor?

 

IM gonna say Olds... I was first.....

 

Im going to agranst the grain here and say its an olds 403/455

 

Thinkin its outta a Prius?

 

Let me be the last to say OLDSMOBILE

The Olds 455. A killer tourqe engine. I like the Prius tho.

 

Hey,

The EGR valve and anti-dieseling solenoid say mid 70s smogger motor

 

That is a feedback quadrajet, in front of the throttle linkage there is a plug for the TPS and on top on the right front there is a plug for the mixture control solenoid. This system requires an ECM to control the mixture and timing. The mixture solenoid duty cycles the primary metering rods to control A/F ratio. The intake also has teh additional temp sensor for this system. If the carb is origional to the engine, think early to mid 80's 307. The distributor is from an earlier engine (vac advance can).

The intake manifold on a 455 is freakishly wide, that does not look like one.

 

I say Olds 307 as well. I'll bet the aluminum looking corrosion on the intake runners in the pics is because it has a factory aluminum intake. If that engine is healthy it would run pretty good with a non feedback Qjet and early HEI. I ran an '83 with the same intake in a '66 something rather. Ran strong and never missed a beat.

 

If it has number cast on the heads (over the exhaust), its a small block Olds.
If it has a letter, its a big block, i.e. 400,425,455.
